PART 1. SYSTEM OVERVIEW

1.1 SIZE AND CONFIGURATIONThe PROSTAR DCS COMPACT is an expandable digital hybrid key telephone systemthat begins with four C.O. line ports and eight keyset ports and expands to ten C.O. lineports and 22 stations (see Figure 1–1). In addition, up to ten keyset daughterboards maybe added to the system to provide the maximum configuration of ten C.O. line ports and32 stations.

Two types of telephones can be connected to the system: proprietary digital stations called“keysets” that connect to DLI (Digital Line Interface) ports and standard telephone sets,generally called “single line telephones” that connect to SLI (Single Line Interface) ports.

The above chart describes configurations using the basic Key Service Unit and 2 x 4expansion cards. However, by using the DCS COMPACT’s unique keyset daughterboards(KDBs), which are installed in the base of a digital keyset, the capacity of the system canbe increased by one station per KDb. Installing a KDb-DLI adds another digital port whilea KDb-SLI adds a single line port. Mix and match these two types of KDb for up to a totalof ten KDBs in the system. Using this method allows the DCS COMPACT to expand to amaximum of 30 stations. Adding the optional 2 SLI card to the Key Service Unit providesa further two SLI ports. The combination of the basic 4 x 8 Key Service Unit plus three 2 x4 expansion cards plus ten KDBs plus a 2 SLI card provides a maximum configuration often C.O. lines and 32 stations plus miscellaneous circuits.

1.2

CONFIGURATION NOTES

1. Only one 2 SLI card can be installed in the system.

2. Only one MISC card can be installed in the system.

3. Only three 2 x 4 cards can be installed in the system.

4. Only ten KDbs can be installed in the system.

��

1.2 TECHNOLOGYSWITCHINGSystem switching is accomplished by means of a custom IC “engine” that provides 256switchable digital channels. Each of the 256 digital channels is automatically assigned tocarry voice or data as required by system operation in a PCM format. In addition to the 256channels mentioned above, the system also utilizes Digital Signal Processors or DSPs.Each DSP may be configured by the switching control program as a DTMF sender, aDTMF receiver or a C.O. tone detector on a per-call basis. The engine chip contains fourDSP channels and an additional four DSPs are added when a MISC card is installed. Thismeans that the system contains a total of eight DSP channels when fully expanded. TheDSP channels are fully shared throughout the system as a common resource.

MEMORY

The system operates using stored program control. This program is stored in either twoEPROM chips (1024 Kbytes of memory) or four EPROM chips (2048 Kbytes of memory)depending on the feature package. All specific customer data is stored in non-volatilerandom access memory (NV-RAM) located on the removable RAM pack. It is protected bya Ni-Cd (NICAD) battery providing up to 30 days of memory protection.

MICROPROCESSORSThe DCS COMPACT uses distributed processing. The system’s primary processor is a 16bit Motorola® MC68000 operating at a clock speed of 8 MHz. The secondary level ofprocessing is done in the keysets. The digital keyset uses a Hitachi H8 processor for datacommunication within the DCS COMPACT.

1.3 PROGRAMMINGThe DCS COMPACT comes with default data. This data provides for operation withinseconds after applying power. All trunks and stations are assigned according to the de-fault numbering plan. This numbering plan is flexible and may be changed if so desired.The technician customizes this default data to meet the end user’s requirements.

The system can be programmed from any display keyset without interrupting normal sys-tem operation. There are three levels of programming: TECHNICIAN, CUSTOMER andSTATION. The technician level has access to all programs and can allow the customeraccess to system programs as needed. Technician and customer access are controlledby different security passcodes.

The DCS COMPACT also allows the use of a proprietary computer program calledCPCMMC. This permits a technician to program the system using a personal computer.CPCMMC can be used on-site to modify the customer database or to download (save) theentire customer database to a file. This file can then be saved as a backup and uploadedwhen required to restore the database.

Through the use of modems, CPCMMC can access a DCS COMPACT system remotely(off-site) to make database changes or perform uploads or downloads of the customerdatabase as if the technician were on-site.

4.1 SYSTEM FEATURE DESCRIPTIONS

ACCOUNT CODE ENTRY

Station users may enter an account code (maximum 12 digits) before hanging up froma call. This account code will appear in the SMDR printout for that call record. Keysetusers may enter this code using an account (ACCT) key without interrupting a conver-sation. Single line set users must temporarily interrupt the call by hook-flashing anddialing the feature access code. Account codes can be up to 12 digits long. Characterscan include the digits 0–9.

FORCED

When forced, they are always verified from a system list of 250 entries. Account codesare always printed on the SMDR report. Account codes can be up to 12 digits long.They can contain the digits 0–9.

VOLUNTARY

Users may elect to enter an account code for any call. Characters can include thedigits 0–9, star (�) and #.

ALL CALL VOICE PAGE

Users can page all the internal and all the external paging zones at the same time bydialing the All Page code. Keysets may be restricted from making or receiving pages insystem programming. A maximum of 30 keysets can be programmed to receive pageannouncements.

ATTENTION TONE

To get your attention, a brief tone precedes all page announcements or intercom voicecalls. There are separate programmable duration timers for page and voice announcetones.

AUTHORIZATION CODES

Authorization codes are used to give permission to make a call. These four digit autho-rization codes can be either forced or voluntary. When used, authorization codes willautomatically change the dialing station’s class of service to the level assigned to theauthorization code. Authorization codes may or may not be programmed to print onSMDR.

FORCED

When a station is programmed for forced authorization the user must always enter thiscode before dialing is allowed. The dialed authorization code is verified from a systemlist of 100 entries.

4.1.2

��

4.1.3

VOLUNTARY

Any station user can always enter an authorization code before he/she begins dialing.The dialed authorization code is verified from a system list of 100 entries.

AUTOMATIC HOLD

While a keyset user is engaged on an outside (C.O.) call, pressing another trunk key,route key or CALL button automatically places the call on hold when this feature isenabled. Pressing TRANSFER, CONFERENCE, PAGE or a DSS key will always auto-matically place a C.O. call on hold. Intercom calls can only be automatically held bypressing the TRANSFER or CONFERENCE keys. Each keyset user can enable ordisable automatic hold.

BACKGROUND MUSIC

Keyset users may choose to hear music through their keyset speakers when optionalexternal sources are installed. Each user may adjust this level by the use of a volumecontrol program at the selected keyset.

CALLER ID

This feature requires that optional software and hardware be installed in the DCSCOMPACT KSU. In addition, the Caller ID service must be provided by your localtelephone company. The availability of the calling party name or number depends onthe type of CID service offered by your local telephone company. The Caller ID featureis dependent on having an LCD keyset to show the name or number in the top line ofthe display.

NOTE: Requires optional hardware and/or software. Ask your dealer for details.

NAME/NUMBER DISPLAY

Each LCD keyset user can decide if he/she wants to see the CID name or CID numberin the display. Regardless of which one is selected to be seen first, the N/N key ispressed to view the other piece of CID information.

NEXT CALL

In the event that you have a call waiting or a camped-on call at your keyset, you canpress the NEXT key to display the Caller ID information associated with this next call inqueue at your station. Either the CID name or CID number will show in the displaydepending on your N/N selection.

SAVE CID NUMBER

At any time during an incoming call that provides CID information, you may press theSAVE key. This saves the CID number in the Save Number feature. Pressing theSAVE number redial key will dial the CID number. The system must be using LCR todial the saved number.

��

STORE CID NUMBER

At any time during an incoming call that provides CID information, you may press theSTORE key. This saves the CID number as a speed dial number in your personalspeed dial list. The system must be using LCR to dial the stored number.

INQUIRE PARK/HOLD

Having been informed that an incoming call is on hold or has been parked, you mayview the Caller ID information before you retrieve the call. This will influence how youchoose to handle the call.

CID REVIEW LIST

This feature allows display keyset users to review CID information for calls sent to theirstations. This list can be from ten to fifty calls in a first-in, first-out basis. The list in-cludes calls that you answered and calls that rang your station but that you did notanswer. When reviewing this list, you can press one button to dial the person back.The system must be using LCR to dial the stored number.

INVESTIGATE

This feature allows selected stations with a special class of service to investigate anycall in progress. If CID information is available for an incoming call, you will know towhom this station is speaking. On outgoing calls, you can see who was called. Afterinvestigating, you may barge-in on the conversation, disconnect the call or hang-up.

WARNING: Barge-in without tone may violate state or federal laws concerning the right toprivacy. STA is in no way responsible for the misuse of this feature.

ABANDON CALL LIST (50)

The system has a system-wide abandon call list that stores CID information for the last50 calls that rang but were not answered. The list is accessed using the system admin-istrator passcode. When reviewing this list, you are provided options to CLEAR theentry or DIAL the number. You can use the NND key to toggle between the CID name,CID number and the date and time the call came in. The system must be using LCR todial numbers from the abandon call list.

CID ON SMDR

The Station Message Detail Records report can be set to include CID name and num-ber for incoming calls. This format expands the print out to 113 characters. You mustuse a wide carriage printer or an 80 column printer set to the condensed print option.

NUMBER TO NAME TRANSLATION (250)

The system provides a translation table for 250 entries. When the CID number isreceived, the table is searched. When a match is found, the system will display thecorresponding name. This will allow users in areas that do not support deluxe Caller IDto provide names for regular callers.

4.1.4

��

CALL FORWARDING

This feature allows the user to redirect (forward) incoming calls. The calls can beredirected to the attendant, a hunt group, voice mail, external number or another sta-tion user. If the destination station is in DND, the calling party will receive DND/REOR-DER tone. Calls cannot be forwarded to a door phone.

FORWARD ALL CALLS

A maximum of 30 keysets can be programmed to receive page announcements. Thistype of forwarding is not affected by the condition of the station. All calls are immedi-ately redirected to the designated destination. If it is desired, the destination stationmay redirect the call back to the forwarded station by using the transfer feature. Theforwarded station user can continue to originate calls as usual. DSS keys for stationsthat are forwarded all will flash slow red.

FORWARD BUSY

This feature forwards all calls only when the station set is busy. The station user canoriginate calls as usual.

FORWARD NO ANSWER

This feature forwards calls that are not answered within a preprogrammed time. Thestation user can originate calls as usual and receive calls if present. The timer is pro-grammable on a per-station basis to allow for differences in individual work habits.

FORWARD DND

This feature works with the Do Not Disturb feature. This allows calls directed to a sta-tion in Do Not Disturb or One Time Do Not Disturb to forward immediately to anotherdestination.

FORWARD BUSY/NO ANSWER

This feature allows the station user to use both of these types of forwarding simulta-neously, provided the destinations have already been entered in the usual manner.

FORWARD FOLLOW ME

This feature allows the station user to forward all calls from another station to the user’sstation or change the forward destination to the extension you are at now.

FORWARD EXTERNAL

This feature forwards C.O. calls to an external number via a central office trunk if al-lowed by class of service. These C.O. calls will only forward after the programmableexternal call forward delay timer expires.

4.1.5

��

FORWARD TO VOICE MAIL

Each station may be programmed to allow or deny the ability to forward intercom callsto voice mail. When denied this can save valuable message time in the voice mailsystem.

CALL HOLD (EXCLUSIVE)Outside calls can be placed on exclusive hold at any keyset by pressing the HOLD keytwice during a call. Calls placed on exclusive hold can only be retrieved at the keysetthat placed the call on hold. Intercom calls are always placed on exclusive hold.

CALL HOLD (SYSTEM)Outside calls can be placed on system hold at any station. Users may dial the accesscode or press the HOLD button. Calls on system hold may be retrieved at any station.

CALL HOLD (REMOTE)Outside calls can be placed on hold at a remote station. This feature allows calls to beanswered at one keyset and placed on hold at another station. This allows time for theuser to proceed to that station or allows the party that the call was intended for to havethat call placed at their station. The call or trunk button will flash at the remote holdstation.

CALL PARK AND PAGE

Each C.O. line has its own park zone. This simple method eliminates confusion andensures that a park zone is always available. Pressing the PAGE key parks the callautomatically. There are no extra buttons to press and there is no lost time looking fora free zone.

CALL PICKUPWith directed call pickup, users can answer calls ringing at any station by dialing acode plus that station’s extension number. Calls can be picked up from a station groupin a similar manner. The group pickup feature allows users to answer any call ringingwithin a pickup group. There are 20 pickup groups available. A station cannot be inmore than one pickup group. To employ this feature, users either dial the access codeor press the assigned feature button followed by the pickup group number.

CALL WAITING/CAMP-ONBusy stations are notified that a call is waiting (camped-on) when they receive a tone.The tone will be repeated at a programmable interval. Keysets receive an off-hook ringsignal through the speaker and single line stations receive a tone in the handset. Thevolume of the camp-on tone can be set by the station user. Camped-on calls will followForward No Answer if a Forward No Answer destination has been set.

4.1.6

��

CENTREX/PBX USECENTREX and PBX lines can be installed in lieu of central office trunks. CENTREXand PBX feature access codes including the command for hook-flash (FLASH) can bestored under one touch buttons. Toll restriction programming can ignore PBX orCENTREX access codes so toll calls can be controlled when using these services.

CHAIN DIALINGStation users may manually dial additional digits following a speed dial call or chaintogether as many speed dial numbers as are required.

CLASS OF SERVICEThe system allows a maximum of 30 station classes of service. Each class of servicecan be customized in memory to allow or deny access to features and to define astation’s dialing class. Each station can be assigned different classes of service forday and night operation.

COMMON BELL CONTROLEach KSU provides a dry contact pair to control a customer-provided common bell orcommon audible device. These contacts must be programmed as members of a sta-tion group and may provide steady or interrupted closure.

COMPUTER TELEPHONY INTEGRATION (CTI)Computer Telephone Integration (CTI) allows integration between the Prostar DCSCOMPACT and a personal computer system (PC). Caller ID service is required onTAPI inbound call applications that use the CID information to display computer recordsin conjunction with the presentation of the call to the station on the DCS COMPACTRelease 2 system. TAPI is described below.

TAPIJointly developed by Intel and Microsoft, TAPI (Telephony Applications ProgrammingInterface) delivers telephony features to the Windows desktop. TAPI is an open appli-cation interface (OAI) protocol that supports First Party Call Control. A DCS ComputerTelephony Module (CTM) is required to connect any keyset to a personal computerrunning Windows 3.1 or Windows 95. The number of CTMs that can be installed on asystem is only limited to the number of keyphones. The features and funcionality of theDCS keyset are not changed.

CONFERENCE

Any combination of up to five parties (stations or outside lines) can be joined togetherin an add-on conference. A station user may set up a conference with two or moreoutside lines and then exit the conference leaving the outside lines connected in anunsupervised (trunk to trunk) conference. The system allows five simultaneous con-ferences.

DATA SECURITY

Single line extensions used with modems and facsimile machines can be programmedso that they will not receive any system-generated tones that would disrupt data trans-missions. In addition, these devices will receive DCS COMPACT C.O. ringing patterninstead of intercom ring pattern. Devices connected to a 2 SLI card or a 2 x 4 SLI cardwill receive a disconnect signal upon termination.

DATABASE PRINTOUT

A copy of the customer database can be obtained using CPCMMC. This information canbe directed to an image file for later printing or to the PC screen and may be done eitheron-site or remotely. A complete database or specific data blocks may be obtained.

DIAL BY NAME

SYSTEM SPEED DIAL LISTEach system speed dial number can have an associated directory name. A speed dialnumber can be selected by scrolling alphabetically through the directory name list.This on-line “directory” allows the user to look up and dial numbers in seconds.

PERSONAL SPEED DIAL LISTEach personal speed dial number can have an associated directory name. A speeddial number can be selected by scrolling alphabetically through the directory name list.This on-line “directory” allows the user to look up and dial numbers in seconds.

STATION DIRECTORY LISTEach station can have an associated directory name. A station can be selected byscrolling alphabetically through the directory name list. This on-line “directory” allowsthe user to look up and dial other users in seconds.

DIRECT IN LINES

Outside lines may be programmed to bypass the operator(s) and ring directly at anystation or group of stations.

DIRECT INWARD SYSTEM ACCESS (DISA)

Users can call in on specific DISA lines at any time, input a security code and receivesystem dial tone. Users can now place internal calls or if permitted, calls using C.O.lines. The caller must have a tone dial phone and know his/her DISA security code.DISA lines can be used as both-way lines or incoming only. The C.O. lines used forDISA must have disconnect supervision.

DIRECT TRUNK SELECTION

Each station can be allowed or restricted access to a trunk or trunk group by access codewhen LCR is activated. When restricted, the user must use a trunk key or route key.

4.1.8

��

DISA SECURITY

Telephone fraud and long distance theft continue to increase; therefore, we have intro-duced a DISA security system. If an incorrect DISA passcode is entered repeatedly(as is the case with “hackers”), the DISA system can be automatically disabled tempo-rarily. Both the number of incorrect passcode attempts and the time that DISA is dis-abled are programmable. In addition, all failed attempts to access DISA will print onSMDR (if provided) with a “DE” DISA error flag.

WARNING: As it is impossible to prevent unauthorized access to your telephone sys-tem by hackers, we suggest that you do not turn the DISA feature on unless you intendto use it. If you do use this feature, it is good practice to frequnetly change passcodesand periodically review your telephone records for unauthorized use.

DISTINCTIVE RINGING

Users will know the type of call they receive by the type of ring that they hear. Outsidecalls have a single ring repeated while internal calls have a double ring repeated.

DIRECT INWARD DIALING (DID)

The DCS COMPACT can use local telephone company-provided DID service via anE & M trunk. When programmed, anyone dialing a user’s personal number rings di-rectly to that user’s office. DID calls to a busy station have the option to return busysignal to the C.O. or return ringback to the C.O. When ringback is selected, the calledstation receives off-hook ring. Multiple DID numbers can ring the same extension orstation group and display keysets show a DID directory name when ringing if a namehas been programmed. DID calls can be assigned both a day and night ring destina-tion. This allows routing of DID calls that have one destination during the system Daymode to be routed to a different destination during the system Night mode. DID callsthat are directed to ring a voice mail machine can be identified by a special digit (seeVoice Mail Integration). As it is possible to program E&M trunks to follow the DIDtranslation tables, the system can use both way DID type service.

DNIS (DIALED NUMBER IDENTIFICATION SERVICE)

DNIS is an incoming service provided by the telephone service provider that translatesthe 10 or 11 digit numbers dialed into 3 or 4 digits, then sends them into the DCSCOMPACT. The DCS COMPACT is considered enhanced because it provides sepa-rate day and night destinations with name display allowing greater call coverage. TheDCS COMPACT supports DNIS on E&M tie line service.

DOOR LOCK RELEASE (PROGRAMMABLE)

After answering a call from the door phone, users can dial a code to activate a contactclosure. This can be used to operate a customer-provided electric door lock releasemechanism. The contact closure timer is programmable from 100–2500 ms.

4.1.9

DOOR PHONES

The door phone interface module (DPIM) provides for connection of a door phone to aDLI port. Pressing the button on the door phone will give a distinctive ring (three shortrings repeated) at the assigned station or station group. If not answered within a pro-grammable time, the system will release the door phone and stop ringing. Stationsmay call the door phone directly and monitor the surrounding areas.

DOOR PHONE NIGHT RING

The night ring destination of door phone calls may be different than during the day. Forexample, large factories may want these calls directed to a security desk after hours.

E & M TIE LINES

Your office can be connected to another office with a tie line. Use this to make calls tostations in the other system. If programming allows, you can access lines in the othersystem to make outside calls. Tie line calls can be put on hold, transferred andconferenced in the same way as are other outside calls. Users accessing the tie linefrom the other system can get a line in your system and make outgoing calls. Thesecalls can be controlled by assigning a dialing class to the tie line. Your local telephonecompany may use E & M tie lines to provide DID service. See DID.

EXECUTIVE BARGE-IN (OVERRIDE)

The feature allows specially programmed stations with a barge-in key to override theautomatic privacy of another station. Programming will allow barge-in with or without awarning tone. Stations may also be programmed as “secure” so that they cannot bebarged-in on.

WITHOUT WARNING TONEWhen the barge-in without tone option is set, the barging-in keyset has its microphonemuted and the barged-in on station will not receive an override display. This feature willnot work from single line sets.

WARNING: Barge-in without tone may violate state or federal laws concerning the right toprivacy. Samsung Telecommunications America is in no way responsible for the misuse ofthis feature.

EXECUTIVE/SECRETARY POOLING

Each keyset may be defined as a BOSS or a SECY in system programming. EachBOSS can have up to four SECYs and each SECY can have up to four BOSSes.These arrangements are known as executive/secretary pools. There can be multiplepools in a system. When a BOSS is in DND, all calls to the BOSS will ring the firstSECY assigned to that BOSS; if that SECY is busy, the call will hunt to the next avail-able SECY assigned to that BOSS. If the SECY must communicate with the BOSSwhile he/she is in DND, pressing the corresponding BOSS button on the SECY’s keyset

4.1.10

��

will result in an Auto Answer intercom call being made to the BOSS (providing theBOSS is free). A station can be the BOSS of only one SECY pool.

EXTERNAL MUSIC INTERFACES

The system provides an interface for connecting a customer-provided external musicsource and the addition of a MISC card provides a second interface. These interfacescan be used for background music, station music on hold or trunk music on hold.

EXTERNAL PAGE INTERFACE

The system provides one external page audio output. The addition of a MISC card willprovide up to four external zone control relays. Multiple relays may be assigned to apage zone.

FLASH KEY OPERATION

While a user is on an outside line, pressing the FLASH key will flash the central officeor PBX. This is used for custom calling features on C.O. lines or in conjunction withCENTREX/PBX operation. System programming allows individual flash times for C.O.and PBX lines. When C.O. or PBX flash is not required, setting the timers for twoseconds will release the existing call and return dial tone to make a new call.

FLEXIBLE NUMBERING

System programming allows stations to have two, three or four digit extension num-bers beginning with the digit 2 or 3. Default extension numbers begin with 201. Stationhunt group access codes can be two or three digits beginning with the digit 5. Thesecan be changed but doing so will affect other feature access codes. All user guides arewritten using the default numbering plan.

FLEXIBLE RINGING

Outside lines can be programmed to ring at any station or station group. Each line canbe assigned a day ring destination and a night ring destination.

HOT LINE

Stations can be programmed to call a pre-defined station or station group as soon asthe handset is lifted. A programmable hot line delay timer (1–250 seconds) can beprogrammed.

IN GROUP/OUT OF GROUP

Individuals assigned to a station hunt group may temporarily remove their telephonesfrom the group by pressing the In/Out of Group button providing that there is someonestill in the group. Stations out of a group will not receive calls to that group but willcontinue to receive calls to their individual extension numbers. When desired, the usermay put him/herself back into the group by pressing the button again. Users who do

4.1.11

��

not have this button may dial the access code and the group desired. A station user isallowed to be in several groups, providing a key and the extender of that group areassigned for each group on the user’s phone.

INCOMING CALL DISTRIBUTIONIncoming calls can be assigned to ring a distributed station hunt group. This will allowall members of the group to share the call load.

INCOMING/OUTGOING SERVICEOutside lines are available for incoming or outgoing service. Programming allows anyoutside line to be used for incoming calls only, outgoing calls only or both-way service.

INDIVIDUAL LINE CONTROLEach station in the system can be individually programmed to allow or deny dialing outas well as allow or deny answering for each outside line.

LEAST COST ROUTINGLeast Cost Routing (LCR) is the ability to automatically select the appropriate trunkgroup for the number dialed by any station. LCR can become quite complicated tounderstand and program but does allow highly complex dialing decisions. The DCSCOMPACT’s LCR package includes the following features:

� Option to use or not use LCR� Programmable LCR access code� Digit analysis table—ten digits each with 500 entries� Routing by time of day� Routing according to individual station class� Modify digits table—100 entries� Flexible trunk group advance timer� Option to use or not use trunk group advance warning tones

LIVE SYSTEM PROGRAMMING

The system can be programmed from any display keyset without interrupting normalsystem operation. There are three levels of programming: TECHNICIAN, CUSTOMERand STATION. The technician level has access to all programs and can allow thecustomer access to system programs as needed. Technician and customer accessare controlled by different security passcodes.

MEET ME PAGE AND ANSWER

After a user makes a Meet Me Page, the user may remain off-hook to allow the pagedparty to meet the user for a private conversation.

4.1.12

��

MEMORY PROTECTION

In the event that power is lost to the system, all customer data contained in the RAMpack is retained by the use of a Ni-Cd (or NICAD) battery for approximately thirty days.In addition, the CPCMMC computer program may be used to produce a backup copyof the customer data.

MESSAGE WAITING INDICATIONS

When calling a station and receiving a busy signal or no answer condition, the callercan leave an indication that a message is waiting. The message button will light red atthe messaged keyset. A single line phone will receive a distinctive message waitingdial tone. Five message waiting indications can be left at any station.

MICROPHONE ON/OFF PER STATION

The microphone can be disabled at any keyset. When a microphone is disabled, thekeyset cannot use the speakerphone although on-hook dialing and group listening arestill possible.

MUSIC ON HOLD—FLEXIBLE

When external music sources are connected, each C.O. line may be programmed toreceive one of the two external sources, internally-generated tones or no music whenit is placed on hold. If there are no sources installed, each line may receive either a 50ms tone or no music. The system-generated tone is a beep every 3.5 seconds.

NIGHT SERVICE

The DCS COMPACT provides separate ringing locations for all trunks in both the DAYand the NIGHT modes.

NIGHT SERVICE (AUTOMATIC)

Automatic night service allows the system to automatically go in and out of night ser-vice according to the system clock. There are separate time options available for eachday of the week. This feature can be overridden by a manual night service key.

OFF PREMISES EXTENSIONS (OPX)

A single line (tip and ring) extension from a 2 SLI card may be connected to telephonecompany-provided OPX circuits to remote locations.

OPERATOR GROUP

Any number of stations can be assigned to the operator group for answering incomingcalls. Calls to this group can be set for distributed, sequential or unconditional ringing.Operators can use the In/Out of Group feature to meet flexible operator requirements.

4.1.13

��

OVERFLOW

When calls ringing a station group go unanswered, they can overflow to another des-tination after a pre-programmed period of time. Each station group has its own timer.The overflow destination can be a station or station group.

PAGING

System software allows the use of four internal and four external paging zones. Stationscan page any individual zone, all internal zones, all external zones or all zones simulta-neously. Using system programming, each station may be allowed or denied the ability tomake or receive page announcements to any zone or combination of zones.

POWER FAILURE TRANSFER

Each system is equipped with two power fail relays. If power fails, these relays can beused to re-route the first two C.O. lines on the card to single line telephones. Whenpower is restored to the system, the lines and stations return to normal operation andcalls in progress will be disconnected.

PRIMELINE SELECTION

Any station can be programmed to select a specific line, line group, telephone number,station or station group.

PRIVATE LINES

For private line use, stations can be prevented from dialing and/or answering any line.

PROGRAMMABLE LINE PRIVACY

Each outside line can be programmed to ignore the automatic line privacy. This allowsup to four other parties to join your conversation by simply pressing the line button.This is similar to 1A2 key telephone operation.

PROGRAMMABLE TIMERS

There are over 35 programmable system timers to allow each installation to be cus-tomized to best fit the end user’s application.

RECALLS

Calls put on hold, transferred or camped-on to any station will recall to the originatingstation if not answered within a programmable period of time. A recall that goes unan-swered for the attendant recall timer will recall to the system operator group. Hold,transfer, camp-on and attendant recalls have individual programmable timers. Callsrecalling to buttons with tri-colored LEDs will flash amber.

4.1.14

��

REMOTE PROGRAMMING

Remote programming allows the technician to access the system database from aremote location for the purpose of making changes to the customer data. Customer-provided modems and a PC using an optional software package will be needed toimplement this feature. A PC can also be connected directly to a MISC card for on-siteprogramming.

RING OVER PAGEAny outside line can be programmed to ring over a customer-provided paging system.Outside lines, door phones and station groups may ring over page in the DAY or NIGHTmode.

SINGLE LINE CONNECTIONSSingle line ports allow for connection of a variety of single line telephones plus fac-simile machines, answering machines, loud bells, computer modems, cordless phonesand credit card machines. When connecting customer-provided equipment to theseextensions, compatibility should be checked out before purchase to ensure correctoperation.

SPEED DIAL NUMBERS (1500)A library of up to 1500 speed dial numbers may be allocated as needed. RAM Pack 1provides 500 speed dial numbers. RAM Pack 2 and Caller ID/CTI software provide1500 speed dial numbers. The system list can have up to 500 numbers and eachstation can have up to 50 numbers. Speed dial numbers are assigned in blocks of ten.Each speed number may contain up to 18 digits.

STATION HUNT GROUPS (30)System programming allows for up to 30 station hunt groups. One of three ring pat-terns are available for each group: SEQUENTIAL, DISTRIBUTED and UNCONDI-TIONAL. Each group may contain a maximum of 30 stations and a station may be inmore than one group. The default directory numbers to call these groups are 501–529.Group 500 is reserved for the operator group and is called by dialing “0.” Each stationgroup has its own recall timer for calls transferred to that group.

STATION HUNT GROUPS (UCD)The UCD group option allows callers in queue at a UCD group to be temporarily diverted toa customer-provided announcement device and then placed back in the queue. A wrap-uptimer allows agents to complete paperwork before receiving the next UCD call.

STATION MESSAGE DETAIL RECORDING (SMDR)The system provides, via an optional MISC card, records of calls made, received andtransferred. Connecting a customer-provided printer or call accounting system will al-low for collection of these records. Each call record provides details of station number,

4.1.15

��

outside line number, start date, start time, duration of call, digits dialed (maximum 18)and an account code if entered. The system may print a header followed by 50 callrecords per page or send continuous records with no header for use with a call ac-counting machine. See the sample printouts.

The SMDR format contains many options that allow it to be customized to a company’sindividual needs. Options to print include incoming calls, outgoing calls, in and out ofgroup status, change in DND status and authorization codes.

TOLL RESTRICTIONThere are 500 allow and 500 deny entries of eleven digits each. Each of these entriescan apply to dialing classes B, C, D, E, F and G. Expensive 976, 1-900, 411 andoperator-assisted calls, as well as specific area and office codes, can be allowed ordenied on a per-class basis. Class A stations have no dialing restrictions and Class Hstations cannot make outside calls.

Any outside line may be programmed to follow station toll restriction or follow the tollrestriction class assigned to it. Each station and trunk can have a day dialing class anda night dialing class.

TOLL RESTRICTION OVERRIDEProgram options allow for system speed dial numbers to follow or bypass a station’stoll restriction class. In addition, users may make calls from a toll restricted station byusing the toll restriction override code.

TONE OR PULSE DIALINGOutside lines can be programmed for either tone or pulse dialing to meet local tele-phone company requirements.

TRANSFERSystem operation permits station users to transfer calls to other stations in the system.Transfers can be screened, unscreened or camped-on to a busy station.

TRUNK GROUPS (11)Outside lines can be grouped for easy access by dialing a code or pressing a button.There are eleven trunk groups available. Access codes are 9 and 80–89.

UNIVERSAL ANSWERStations may dial the Universal Answer (UA) code or press the UA key to answer anyoutside lines programmed to ring the UA device. The UA device can be a station,group of stations, common bell or ring over page.

VOICE MAIL INTEGRATIONThis feature uses DTMF tones (inband signaling) to communicate with any compatiblevoice mail system. Stations can call forward to a voice mail system. When answered,the system will send DTMF tones routing the caller directly to the forwarded stationuser’s mailbox. Keyset users can press one button to retrieve messages from thevoice mail system.

Some additional options of this feature concern overflow and message retrieval. Be-cause of the complex nature of this feature, check the DCS COMPACT TechnicalManual for more details.NOTE: Although most voice mail systems will work on the DCS COMPACT, the sys-tem data has default values set to work with the Starmail Voice Processing System.

WALKING CLASS OF SERVICE

This feature allows users to make calls or use features from a station that is restricted.Either use the WCOS feature code or the authorization code feature. Both methodswill change the class of service to correspond with the passcode or authorization codethat is dialed. After the call is completed, this station returns to its programmed class ofservice.

AUTOMATIC HOLD

Station users can enable or disable automatic hold at their keysets. While engaged onan outside (C.O.) call, pressing another trunk key, route key or CALL button automati-cally puts the call on hold when this feature is enabled. Pressing TRANSFER, CON-FERENCE, PAGE or a DSS key will always automatically place a C.O. call on hold.This type of automatic hold is not a user-selectable option.

AUTOMATIC PRIVACY

All conversations on outside lines and intercom calls are automatically private. Theprivacy feature can be turned off on a per-C.O. line basis.

BACKGROUND MUSIC

When customer-provided music sources are connected, each keyset user may listento background music. The HOLD button turns BGM on or off and the volume is con-trolled by the volume control keys. One source is located in the KSU. A second sourceis located on the optional MISC card.

BUSY STATION CALLBACK

When reaching a busy station, callers may request a callback by pressing one buttonor dialing a code. The system rings the caller back when that station becomes idle (asystem-wide maximum of 100 callbacks are allowed at one time including busy stationand busy trunk).

BUSY STATION INDICATIONS (BLF)

DSS/BLF keys may be assigned to any keyset or add-on module. These buttons willbe off when the station is idle, light red when that station is in use and flash distinctivelywhen that station is in DND mode.

CALL FORWARDING

Station users can forward internal and outside calls to other destinations immediately(Forward All), when busy (Forward Busy) or if not answered in a programmable num-ber of seconds (Forward No Answer). These forward destinations can all be different.Once a destination has been programmed, it can be turned on and off with a program-mable key. Forward All Calls takes priority over Busy and No Answer conditions. Inaddition to the three usual methods of forwarding described above, a fourth optioncalled Follow Me is available. This option allows station users to set a Forward Allcondition from their station to another station while at the remote station.

Keyset users can also be given an External Call Forward button to forward their calls toan external phone number. Each outside line may be programmed to either follow orignore station call forwarding. A per-station option allows internal calls to either for-ward or not forward to voice mail. Single line telephone users must have the systemadministrator program this feature for them.

CALL PICKUPWith directed call pickup, a user can answer new calls ringing at any station by dialinga code plus that extension number. The group pickup feature allows you to answer anycall ringing within a pickup group. Pickup keys may be customized with extenders toallow pickup from a specific station or pickup group. The DCS COMPACT has 20programmable pickup groups.

DIAL BY NAMEEach system and personal speed dial number can have an associated directory name.A speed dial number can be selected by scrolling alphabetically through the directoryname list. This on-line “directory” allows the user to look up and dial numbers inseconds.

DIRECT STATION SELECTION (DSS)Programmable keys can be assigned as DSS keys and associated with extension num-bers. Users press these keys to ring or transfer C.O. calls to the assigned stations.

DO NOT DISTURB (PROGRAMMABLE)The Do Not Disturb (DND) feature is used to stop all calls to a station. System pro-gramming can allow or deny use of the DND feature for each station. Parties calling astation in DND will receive reorder tone. When in the DND mode, calls may be for-warded to another destination. See Forward DND option. There is also a program-mable option to allow a C.O. line to override DND at its ring destination if that destina-tion is a single station.

DOOR LOCK RELEASEStations programmed to receive calls from a door phone can dial a code to activate acontact closure for control of a customer-provided electronic door lock.

EXCLUSIVE HOLDPressing the HOLD button twice will hold a call exclusively at that station so no otherstation can pick up that call. Intercom calls are automatically placed on exclusive hold.

GROUP LISTENINGA keyset assigned this feature button may turn on the speaker while using the hand-set. This allows a group of people to listen to the distant party over the speaker withoutturning on the microphone.

HEADSET OPERATIONEvery keyset can be programmed to allow for the use of a headset. In the headsetmode, the hookswitch is disabled and the ANS/RLS key is used to answer and releasecalls. Keyset users may turn headset operation ON/OFF by keyset programming ormore easily by pressing the headset ON/OFF key. The headset key lights steady redwhen the keyset is in headset mode.

MESSAGE WAITING LIGHT/INDICATION

When a message indication is left at a keyset, the MESSAGE button will slowly flashred. Single line telephone users will receive a distinctive dial tone to notify them that amessage is waiting. Message waiting indications can be left for any station.

MUTE MICROPHONE/HANDSET

Any keyset can mute the handset transmitter by pressing a MUTE key. In addition,keysets can also mute the keyset microphone while in speakerphone mode.

OFF-HOOK RINGING

When a keyset is in use, the system will provide an off-hook ring signal to indicate thatanother call is waiting. The ring signal is a single repeated ring. The interval is con-trolled by a system-wide timer. Single line stations will receive a tone burst through thehandset receiver instead of a ring.

OFF-HOOK VOICE ANNOUNCE

STANDARD

Keysets may receive a voice announcement while on another call. The calling stationmust have an OHVA key. When transferring a call to a busy keyset or while listening tobusy signal, the station user can press the OHVA key to make an OHVA call to thebusy keyset. If the called keyset is in the DND mode, it cannot receive OHVA calls.

EXECUTIVE

without interrupting the call in progress. Only keysets with an off-hook voice announcebutton (OHVA) can off-hook voice announce to keysets with AOMs.

ONE TIME DO NOT DISTURBThe Do Not Disturb (One Time) feature is used to stop all calls to a station when theuser is on an outside line and does not want to be disturbed for the duration of the call.Upon completion of the call, DND is canceled and the station is returned to normalservice. This feature requires a programmed button.

ONE TOUCH DIALING KEYS

Frequently used speed numbers can be assigned to one touch dialing keys for fastaccurate dialing.

ON-HOOK DIALINGAny keyset can originate calls without lifting the handset. When the called party an-swers, speak into the microphone or lift the handset for more privacy.

PROGRAMMABLE KEYSThe LCD 24B and STD 24B keysets have 24 programmable keys and the LCD 12Band Basic 12B keysets have 12. Each key can be programmed for over 25 differentuses, personalizing each phone. Examples of keys include: individual outside line,individual station, group of lines, group of stations and one touch speed dial buttons.Using these keys eliminates dialing access codes.

The following keys have extenders that identify what station, group or number thatfeature key applies to: SPEED DIAL KEY, PAGE, DSS, DIRECTED PICKUP, GROUPPICKUP, DOOR PHONE, BOSS, PROGRAMMED MESSAGE and FWD.

PROGRAMMED STATION MESSAGESAny station may select one of twenty messages to be displayed at a calling party’skeyset. Ten messages are factory-programmed and the remaining ten can be custom-ized by the system administrator (16 characters maximum).

NOTE: The calling party must have a display keyset to view these messages.

PROTECTION FROM BARGE-INEach station can be programmed as secure or not secure. Secure stations cannot bebarged-in on. A non-secure station talking to a secure station cannot be barged-in on.
