Note: Leave the System in position 0 8. Press and release the CPU Reset button 9. Wait 2 minutes. After 2 minutes, the Run light will be green and the Off-line light will slowly flash yellow. 65
System Startup Procedure 10. The system is now in the Off-line mode. Only system administration can be performed. 11. Turn the Mode Switch to position “ 1”. It is very important that the Mode Switch be placed in position ” 1” at this time. If the system were to be reset, or if the AC power were to be lost momentarily, the system would re-initialize and return to the default condition. Any programming changes that you may have been made would have been lost. 66
System Startup Procedure 12. To place the system into the On-line Mode, press and release the CPU Reset button. 13. Wait 2 minutes. After the 2 minute waiting period, the system will be On-line. The Run light will be lit, and the Off-line and Alarm light will be off. Call processing can be accomplish as well as system administration in the On-line mode. Only the Upload to PBX function can not be performed 67
Activity Two System Startup Purpose: To become familiar with the system startup procedure 1. Execute the system startup procedure 68
KX-TD 500 Hardware Addresses z. The KX-TD 500, like most other universal free slot designed PBX’s, utilize a numbering system to identify ports, cards, and shelf locations. z. This is necessary when programming and maintaining the system 69
KX-TD 500 Hardware Addresses z. Generally hardware address will be either 3 digit or 5 digit numbers. z. Example: 10205 y. 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-TD 500 Hardware Addresses z. Example: 10205 y. 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 0114 71
KX-TD 500 Hardware Addresses z. Example: 10205 y. 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. y. For example, a DLC is a 16 port card and would have valid entries of 01 -16. 72
KX-TD 500 Hardware Addresses z. Example: 10205 y. 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-TD 500 Hardware Addresses z. A card with twenty-four port identifiers (01 -24) is the T 1 card z. Cards with sixteen port identifiers (01 -16) include: DLC, DHLC and ESLC z. Cards with eight port identifiers (01 -08) include: HLC, PLC, SLC-M, LCOT, GCOT & ELCOT 74
KX-TD 500 Hardware Addresses z. Cards with four port identifiers (01 -04) include: OPX, DID, DISA, AGC & DPH z. Cards that only have no port identifier include: RMT and ERMT 75
Port Status z. Ports and cards can be in various states of service z. Operational devices are usually In-Service or the abbreviation “INS” z. Disabled devices are usually Out-of. Service or the abbreviation “OUS” z. Another state is Fault. This can be caused by several things including configuration problems as well as hardware failure 76
Port Status z. 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. z. Generally the “INS” and “OUS” states are most common. Changing from one to another is accomplished by using different screens from within the KX-TD 500 Maintenance Console programming tool 77
Port Status z. 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. 78

D 4/SF z. D 4 or Superframe was introduced in 1974. The D 4 was derived from the first Telco channel bank which utilized this type of frame formatting. z. D 4/SF framing consists of a superframe made up of twelve individual frames z. The twelve framing bits within the superframe follow a pattern of 100011011100 112

D 4/SF z. D 4 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 6 th and 12 th frame. z. This call control information is used for dialing and other line maintenance functions. z. 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) z. 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 z. 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) z. 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 z. The Embedded Operation Channel is an Out-of-Band call control method used for signaling, diagnostics as well as other functions. 116

Extended Superframe (ESF) z. 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 B 8 ZS? z. Alternate Mark Inversion and Binary 8 Zero Substitution are the two Line Coding formats used in North America for T 1 lines z. The purpose of Line Coding is to maintains synchronization by ensuring that no more than 7 consecutive “ 0’s” are transmitted within a DS 0. 119
Signaling Formats z. Unipolar Signaling y. Used internally within most DTE equipment such as the KX-TD 500 and computers +5 v 0 1 1 0 0 0 v z. Bipolar Alternate Mark Inversion y. T 1 lines utilize this type of signaling format +3 v 0 1 1 0 0 0 v -3 v 120
AMI Line Coding z. 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. z. 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 0 0 0 0 1 Ov -5 v CSU set for AMI sends +5 v Ov -5 v 122
B 8 ZS Line Coding z. Binary 8 Zero Substitution is the most popular Line Coding technique used in North America. z. B 8 ZS uses a method of inserting a particular bit pattern which includes intentional bipolar violations to replace a series of 8 “ 0’s” z. This is the preferred Line Coding technique since it allows for 64 Kbps 123
B 8 ZS Line Coding +5 v DTE Sends 1 0 0 0 0 B 0 1 Ov -5 v Previous Word CSU set for B 8 ZS sends +5 v 1 1 0 Ov -5 v B = Bipoalar Violation 124
