The RACOM 2816P Dialed Number Recorder evolved from the Racom 2800and 2805 Dialed Digit Printers. The RACOM 2816P is a one lineportable version of the RACOM 2816 Multi-line Dialed Digit Printer.The 2816P contains the latest state-of-the-art microprocessorcircuitry with plug-in circuit boards.

The RACOM 2816P Dialed Number Recorder can easily be connected tomost telephone lines by its modular connector to provide a printedrecord of the following:

1. Each telephone number dialed (up to 32 digits).

2. The date and time of the call.

3. The elapsed time of the call.

4. Whether the call was made from a rotary dial or a touchtone telephone.

5. How long an incoming call rang and if it was answered.

6. The origination date and time of the incoming calls.

7. The elapsed time of the incoming calls.

8. Control and status of a cassette recorder.

9. The number that is calling when Caller Number Deliver isprovided on the telephone line.

The 2816P has connections for two cassette recorders and aheadphone. It can be connected directly across the telephone lineor it may be used with a remote loop extender, such as the RacomModel LP2816.

The information can also be displayed on the RACOM 2816Ps LCDdisplay.

The 2816P has an optional RS232 data output which can hold up to 750calls waiting to be sent out through the RS232 data output.

Once connected properly to a telephone line, the RACOM 2816P isfully automatic and requires a minimum amount of attention. Theonly normal operating maintenance required is changing the paper andinked ribbon.

RECORDING AND AUDIO MONITORING

The Racom 2816P has connectors for two cassette recorders and aaudio monitor jack. Audio is on the miniature connecters (1/8 inchdiameter). The subminiature connecters (Marked motor) connect tothe remote jack on the recorders and they enable the recorder'smotor to run under control of the 2816P. The 2816's printoutindicates what calls (or parts of calls) are recorded. The recorderand audio circuits are toggled on and off automatically withtelephone usage or they may be controlled manually from thekeyboard.To turn the audio and recorder on and off, put the LCD in the linedisplay mode by pressing the "1" key. The recorder and the audiomonitor may now be toggled with the "B" key. When it is toggled an"R" or an "0" will appear on the LCD. "R" indicates that the unitwill record and "0" indicates that the recorder is off.

When the line being monitored is in use (active), toggling therecorder will cause a printout to occur. The right side of thepaper shows two letters (R or 0), the first letter (to the left)shows recorder status before the change and the second letter(closest to the edge) shows the new status.When the telephone is hung up, only one letter is printed. Thisshows the record's status at the end of the call.When the telephone is on-hook the recorder is always off. However,what the recorder does when the telephone goes off-hook may bechanged with the "B" key and is controlled by a variable called"Rec". See the software set section for more information on this.

LOOP EXTENDER RECEIVER

f c r ^ I

The Racom 2816P has a receiver for a remote loop extender. Thisallows the 2816P to receive signals from a remote dual tone loopextender or slave, such as the RACOM Model LP2816. The tonefrequencies are 852 Hz and 1633 Hz. The receiver is enabled whenthe mode switch is in the REMOTE position.

The 2816 may be ordered with other tone frequencies or for signaltone operation.

An optional 48 Volt power supply (Option F) can be used to power theremote loop extender. The power supply and the remote receiver isenabled when the mode switch is in the REM0TE/48V position.

SECTION TWO

This section deals with the RACOM 2816 from a more technicalviewpoint than section one. Internal adjustments or modificationsshould be made only by technically qualified personnel.

CONFIGURATION

Before the RACOM 2816 is shipped, we carefully check out allfunctions. We configure the unit so it will work on most phonelines without reconfiguration. The RACOM 2816 is very versatile andit has many uses. This section deals with the configuration andsetup of the RACOM 2816 to make it do particular things. The RACOM2816 is configured in two ways. The first being with internalswitches and the second being with the setup of software parameters.

INTERNAL SWITCHES AND CONTROLS

ACCESS TO INTERNAL SWITCHES AND CONTROLS

The internal switches and controls discussed in this section arelocated behind the front panel. Access to these internal switchesand controls can be gained by opening the small flap underneath thecase.

Most switches have two positions - A or B. The switch is open inPosition B and closed in Position A. A switch is in Position B whenthe rocker is flush with the front edge of the switch. Switcheswith toggle levers are in Position B when the toggle lever is towardthe front.

Position A is when the flat or toggle lever is toward the rear ofthe switch.

DOUBLE OR SINGLE SPACE

The RACOM 2816 can either double space or single space between calltransactions. Double spacing provides a clear separation betweencalls for transcribing.

Section 7 of switch SW103 controls this feature.

SW103 Section 7 Pos. A - Single space

Pos. B - Double space

- 11 -

TOUCH TONE AND DIAL PULSE EXCLUSION

All units are equipped with a feature that will shut down either thetouch tone or rotary dial pulse decoders after the first digit of anumber is decoded. If the digit is a touch tone digit, the rotarydial pulse decoder will be shut down. If the digit is pulsed, thenthe touch tone decoder will be shut down. This feature helps reducefalsing. SW103, Section 6 controls this feature.SW103 Section 6 Pos. A - No exclusion

Pos. B - Exclusion feature is enabled asdescribed above.

PRINT LAST ROTARY DIALED DIGIT

Normally, a rotary dialed digit is entered into the RACOM 2816smemory after a valid amount of inter-digit time has elapsed. Insome specialized applications, line current is reversed or removedbefore the inter-digit time has elapsed. So that the last digit isnot lost in these applications, place SW103, Section 2 in PositionA. Doing this will also result in the RACOM 2816s registering touchtone or rotary dialed digits that are received before line activetime has been exceeded.

SW103 Section 2 Pos. A - Print first/last rotary dialeddigit if it was not finished.

Pos. B - Normal

TOUCH TONE ACCEPTANCE OR DROPOUT TIME

Touch tone acceptance is the time in which touch tone digits areaccepted by the printer. The acceptance time begins when the lineactive LED lights and resets each time a touch tone digit isentered. After the acceptance time is exceeded, no more touch tonedigits will be accepted until after the system has been restored toan "on-hook" condition. This feature is designed to prevent"falsing" caused by frequencies contained in speech.The length of time is set by setting the variable "T Tone" to thedesired time. Set "T Tone" to 255 for infinite touch tone acceptancetime.

ROTARY DIAL PULSES TIMEOUT

Thirty seconds after a call has been started, the rotary dial pulsew decoder for a line will be shut down. This is called rotary dialpulse timeout and it is controlled by the variable "Pulse". Toilluminate rotary dial pulse timeout, set the variable "Pulse" to255.

The RACOM 2816 has a D. C. line voltage detector circuit in it.This circuit detects if the phone is on or off the hook and decodesrotary dial pulses. The telephone line voltage which causes theRACOM 2816 to recognize an off or on hook condition is called thethreshold voltage.The threshold voltage is set by Pot R463 and monitored by them "Pulse" LED. There is one R463 per line as there is one "Pulse" LEDper line. Once the R463 and the "Pulse" LED for a particular linehave been located, they may be adjusted as follows:With normal bridging mode operation, this LED is illuminated whenL the line voltage is low and off when the line voltage is high.

m R463 should be adjusted so that this LED is illuminated when thephone is off the hook and off when the phone is on the hook.

p When the phone generates rotary dial pulse, this indicator should[ flash in sequence with the dial pulses. If it does not, then touchup the adjustment of R463.

Note: Some exchanges may generate pulses on the line before or afterrotary dial sequences. These will usually make this indicatorLED flash. If this happens, R463 and dial pulse rate switchmay be used to make the printer reject these pulses.

For each line in a RACOM 2816, there is a Dial Pulse Rate Switch.This switch selects the maximum dial pulse rate to be decoded by theRACOM 2816. This is Section 1 of Switch 401 on the line board.With the switch in position A, the maximum dial rate is 13 P.P.S.With the switch in position B, the maximum dial rate is 21 P.P.S.

INPUT INVERT SWITCH

For each line in a RACOM 2816, there is a switch that inverts thesignal from the threshold detector. For normal operation, , theswitch for a particular line should be in position B. Put the switchin position A to invert the input. This switch is Section1 4 ofSwitch 401 on the line board.

D. C. INPUT CONFIGURATION

i^S

Usually, the Racom Model RACOM 2816 Multiline Dialed Digit Printeris operating in a bridging mode. This means that the RACOM 2816s ^high impedance inputs are connected across the telephone line.The RACOM 2816 has separate A.C. and D.C. bridging inputs for each mline. Normally, for each line, these A.C. and D.C. inputs will beconnected across the phone line for that line.

For bridging operation, these internal switches should be set as Hf o l l o w s o n t h e a p p r o p r i a t e l i n e b o a r d s : J

SOFTWARE SETUP

pP

PP|

ifS|

Many of the operating parameters for the RACOM 2816 are contained inthe software. These parameters or variables are factory preset andstored in a memory chip called an EPROM. However, some parametersmay be changed to suit user requirements. These parameters are userprogrammable and are stored in a non-volatile memory chip called aNOVRAM. The working memory of the RACOM 2816 is in the CPU chip^Upon power up or reset and approximately every two hours, the CPUselects the operational parameters from either the EPROM or theNOVRAM, depending on Switch 103 Section One (See MicroprocessorBoard section).

To make the parameter changes, the user must enter the softwaresetup mode. The software setup mode is entered by hitting the F keyand then the D key on the keyboard. Now the display will give achoice of several options. Please enter the digit shown for theoption you want. These options are as follows:
