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.

67. 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

68. Activity Two System Startup
Purpose: To become familiar with the system startup procedure
1. Execute the system startup procedure

69. 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

70. 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

71. 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 In the Expansion Shelves, valid entries would be 01-14

72. 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

73. 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.

74. 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

75. 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

76. 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

77. 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

78. 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.

111. 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

112. D4/SF
D4 or Superframe was introduced in 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

113. D4/SF Superframe Superframe Frame 1 Frame 2 Word F1 F2 F4 F3 F5 F6 F8
Ch1
Ch2
……...
Ch24
Frame 1 F
Ch1
Ch2
……...
Ch24
Frame 2 1 1 1 1
Word
Frame 2 framing bit

114. 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.

115. 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 that the far end equipment synchronizes on.

116. 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.

Only 15 of the 24 frames are shown

118. 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.

119. 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.

120. Signaling Formats Unipolar Signaling Bipolar Alternate Mark Inversion
Used internally within most DTE equipment such as the KX-TD500 and computers

121. 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

123. 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
