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 69

KX-TD500 Hardware Addresses

 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 70

KX-TD500 Hardware Addresses

 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 71

KX-TD500 Hardware Addresses

 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. 72

KX-TD500 Hardware Addresses

 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.

73

KX-TD500 Hardware Addresses

 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 74

KX-TD500 Hardware Addresses

 Cards with four port identifiers (01-04) include: OPX, DID, DISA, AGC & DPH  Cards that only have no port identifier include: RMT and ERMT 75

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 76

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 77

Port Status

 Within 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 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 111

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 112

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. 114

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.

115

Extended Superframe (ESF)

 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.

Extended Superframe (ESF)

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

118

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.

119

Signaling Formats

 Unipolar Signaling  Used internally within most DTE equipment such as the KX-TD500 and computers 0 1 1 0 0 1 0 0 +5 v 0 v  Bipolar Alternate Mark Inversion  T1 lines utilize this type of signaling format +3 v 0 1 1 0 0 1 0 0 0 v -3v 120

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 121

AMI Line Coding

+5 v DTE Sends O v -5 v 0 0 0 0 0 0 0 0 CSU set for AMI sends +5 v O v -5 v 0 0 0 0 0 0 0 1 122

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 123

B8ZS Line Coding

+5 v DTE Sends O v -5 v 1 0 0 0 0 0 0 0 0 Previous Word CSU set for B8ZS sends +5 v O v -5 v 1 0 0 0 B 1 0 B 1 B = Bipoalar Violation 124
