This TD-based system will offer a smooth upgrade path for 2-cabinet TD1232 users as well as a starter system for the medium-sized businesses or high-end residential users

6

KX-TD500Digital Super Hybrid

The system will provide the TD dealers with a larger system size, but offer a similar programming and user interface as currently offered by the TD308/816/1232.

The major differences between the existing TD line of systems and the KX-TD500 includes a new Windows-based programming tool, and the universal slot design.

7

KX-TD500 System Outline

The KX-TD500 consists of a basic shelf and up to two expansion shelves.

The systems features a universal slot design enabling station, CO, and other function cards to be installed into free slots in the cabinets.

8

Basic ShelfKX-TD500

The Basic Shelf is the initial building-block of the KX-TD500 system allowing a single-cabinet system to be configured with up to a maximum of 192 ports.

The Basic Shelf then provides the foundation on which the system can be expanded by use of expansion shelves to configure a system up a maximum of 512 ports.

9

Basic ShelfKX-TD500

The Basic Shelf houses the system’s common control cards including the Central Processing Unit (CPU) card and the Time Switch (TSW) card.

Only the TSW card is included with the Basic Shelf which includes the DOHCA and TSW-CONF cards

The CPU card is available separately.

10

KX-TD500 Hardware Addresses

The KX-TD500, like most other universal free slot designed PBX’s, utilize a numbering system to identify ports, cards, and shelf locations.

This is necessary when programming and maintaining the system

68


Generally hardware address will be either 3 digit or 5 digit numbers.

Example: 10205 The first digit (1) indicates the shelf. In

this example the 1 indicates the Basic Shelf. The first expansion shelf would be identified with a 2 and the second expansion shelf identified with a 3

69


Example: 10205 The next two digits (02) indicate the slot

number. In this example the card is located in the Basic Shelf in slot 2. In the Basic Shelf, valid entries would be 01-12. In the Expansion Shelves, valid entries would be 01-14

70


Example: 10205 The next two digits (05) indicate the

port number. Port number identifiers will vary based on the card type. Some will have up to 16 ports, others 8 or less.

For example, a DLC is a 16 port card and would have valid entries of 01-16.

71


Example: 10205 A DHLC is slightly different. The first 8

port identifiers (01-08) are used to identify the 8 proprietary ports on this card. The second 8 port identifiers (09-16) are used to identify the XDP ports. For example, port identifier 09 is used to program the XDP single line extension for port 01.

72


A card with twenty-four port identifiers (01-24) is the T1 card

Cards with sixteen port identifiers (01-16) include: DLC, DHLC and ESLC

Cards with eight port identifiers (01-08) include: HLC, PLC, SLC, SLC-M, LCOT, GCOT & ELCOT

73


Cards with four port identifiers (01-04) include: OPX, DID, DISA, AGC & DPH

Cards that have no port identifier include: RMT and ERMT

74

Port Status

Ports and cards can be in various states of service

Operational devices are usually In-Service or the abbreviation “INS”

Disabled devices are usually Out-of-Service or the abbreviation “OUS”

Another state is Fault. This can be caused by several things including configuration problems as well as hardware failure

75

Port Status

The final state of service is called Busy-out. This occurs on CO ports that have been placed in the Busy-out state by a system administrator.

Generally the “INS” and “OUS” states are most common. Changing from one to another is accomplished by using different screens from within the KX-TD500 Maintenance Console programming tool

76

Port StatusWithin the Maintenance Console

programming tool, the state of service can be identified and changed by clicking on the “Status” button. The text on the “Status” button indicates the current state, and the state can be toggled from one state, for example OUS, to the alternative state, in this case INS, by clicking on the “Status” button and then selecting OK.

What is T1?

T1 is the telephone companies infrastructure (copper wire, transmission equipment,…) that provides a high speed digital telephone circuit between two points.

T1 circuits operate at a rate of 1.544 Mbps or at what is referred to as DS1

A DS1 is comprised of 24 64 Kbps* channels (DS0) plus framing overhead

* Certain line code and frame selections can reduce the available bandwidth from 64 to 56 Kbps

83

T1 Channel Service Unit

A T1 Channel Service Unit (CSU) is required for each T1 line that is to be connected to the KX-TD500

For a basic TD500 T1 installation, only a CSU is required.

CSU’s come in a variety of configurations based on the application and prices will vary.

84

86

What is D4/SF and ESF?

Superframe (SF) or D4, and Extended Superframe (ESF) are the two frame formats used in North America.

Frame formats are used for frame synchronization and also for line management tasks

The KX-TD500 supports either frame formats

87

D4/SF

D4 or Superframe was introduced in 1974. The D4 was derived from the first Telco channel bank which utilized this type of frame formatting.

D4/SF framing consists of a superframe made up of twelve individual frames

The twelve framing bits within the superframe follow a pattern of 100011011100

89

D4/SF

D4 or SF framing uses an in-band call control method called “bit robbing” which robs the least significant bit from each of the 24 channels within the 6th and 12th frame.

This call control information is used for dialing and other line maintenance functions.

This frame format restricts the channel bandwidth to 56 Kbps rather than 64 Kbps and is used most often in voice applications.

90

Extended Superframe (ESF)

Extended Superframe is the preferred method of framing since it utilizes a larger number of frames (24 frames) and requires fewer framing bits to maintain synchronization

Framing bits for frames 4, 8, 12, 16, 20, are set to the pattern of 001011 that the far end equipment synchronizes on.

91


Since fewer frames require framing bits, the excess framing bits for the other frames can be used for other functions such as Cyclic Redundancy Checks and for an Embedded Operations Channel

The Embedded Operation Channel is an Out-of-Band call control method used for signaling, dialing, diagnostics as well as other functions.

Only 15 of the 24 frames are shown

93


ESF should be used whenever possible since it has a more sophisticated diagnostic and maintenance capability and allows for a 64 Kbps channel bandwidth.

94

What is AMI and B8ZS?

Alternate Mark Inversion and Binary 8 Zero Substitution are the two Line Coding formats used in North America for T1 lines

The purpose of Line Coding is to maintains synchronization by ensuring that no more than 7 consecutive “0’s” are transmitted within a DS0.

95

Unipolar Signaling Used internally within most DTE equipment such as the KX-TD500 and computers

Bipolar Alternate Mark Inversion T1 lines utilize this type of signaling format

AMI Line Coding

AMI get around the 1’s density requirement by forcing a 1 into the bit stream or what is called “bit stuffing.” The CSU accomplished this task by inserting a 1 into the least significant bit location.

The draw back to this method is that it reduces the available user bandwidth to 56 Kbps

B8ZS Line Coding

Binary 8 Zero Substitution is the most popular Line Coding technique used in North America.

B8ZS uses a method of inserting a particular bit pattern which includes intentional bipolar violations to replace a series of 8 “0’s”

This is the preferred Line Coding technique since it allows for 64 Kbps
