62Activity One Shelf and Card Installation Purpose: To assemble a shelf and install cards in a shelf1. Install an Expansion Shelf on a Basic Shelf2. Install all cards into the Basic Shelf leaving slots 09 and 10 empty. Also make sure that slot 01 has either a DLC or DHLC installed in it. This will be necessary for practice exercises at a later time.
63System Startup Procedure System startup or initialization must be executed for every systemThe purpose of this procedure is to default the system and to automatically assign installed hardware into their respective positionsThis procedure is accomplished using rotary switch labeled “Mode” on the CPU card
64System Startup Procedure 1.Ensure that all cards that are to be initially installed are properly seated in the card slots and that the cabinets are properly assembled.2.Connect the AC power cord to the Basic Shelf and then to a properly grounded and protected AC outlet3.Connect a ground wire to the Ground terminal (Not necessary in training environment)4.Turn On the Main Power Switch on the Basic Shelf5.Turn On the Power Switch for each Expansion Shelf
65System Startup Procedure 6. Turn On the Power Switch for the Basic Shelf7. Using a small flathead screwdriver, turn the Mode Switch on the CPU to position “5”. Note: Leave the System in position 08.Press and release the CPU Reset button9.Wait 2 minutes. After 2 minutes, the Run light will be green and the Off-line light will slowly flash yellow.
66System 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.
67System 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
68Activity Two System Startup Purpose: To become familiar with the system startup procedure1. Execute the system startup procedure
69KX-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
70KX-TD500 Hardware Addresses Generally hardware address will be either 3 digit or 5 digit numbers.Example: 10205The 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
71KX-TD500 Hardware Addresses Example: 10205The 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
72KX-TD500 Hardware Addresses Example: 10205The 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
73KX-TD500 Hardware Addresses Example: 10205A 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.
74KX-TD500 Hardware Addresses A card with twenty-four port identifiers (01-24) is the T1 cardCards with sixteen port identifiers (01-16) include: DLC, DHLC and ESLCCards with eight port identifiers (01-08) include: HLC, PLC, SLC, SLC-M, LCOT, GCOT & ELCOT
75KX-TD500 Hardware Addresses Cards with four port identifiers (01-04) include: OPX, DID, DISA, AGC & DPHCards that only have no port identifier include: RMT and ERMT
76Port 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
77Port StatusThe 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
78Port 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.

105What 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 Mbps or at what is referred to as DS1A DS1 is comprised of Kbps* channels (DS0) plus framing overhead* Certain line code and frame selections can reduce the available bandwidth from 64 to 56 Kbps
106T1 channels 24 bits per word x 8 bits 192 samples/sec x 8000 user data 1,536,000 bpsframe bitsline speed 1,544,000 bps
107Digital Trunking T1 demarc at customer premise T1 Channel Service Unit PSTN:Local Exchange Carrier (LEC)orInterexchange Carrier (IEC)TD500 equipped with KX-TD97187
108T1 Channel Service UnitA T1 Channel Service Unit (CSU) is required for each T1 line that is to be connected to the KX-TD500For 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.
109T1 Channel Service Unit CSU Functions: It is the first piece of Customer Premise Equipment (CPE) after Telco’s demarcation point.Provides a 100 Ω circuit terminationProvides FCC Part-68 protectionInitiates and facilitates loopback testingMonitors line for errors and violationsMaintain 0’s and 1’s densitySupports Line Coding and Framing requirements
110Adtran ESF T1 CSU ACEFull featured T1 CSU suitable for wall or desktop use.Front panel LCD and four user keys provides easy configuration and unit monitoringPhysical Interface RJ-48CSupports D4/SF or ESFSupports AMI or B8ZS
111What 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 tasksThe KX-TD500 supports either frame formats
112D4/SFD4 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 framesThe twelve framing bits within the superframe follow a pattern of
113D4/SF Superframe Superframe Frame 1 Frame 2 Word F1 F2 F4 F3 F5 F6 F8 Ch1Ch2……...Ch24Frame 1FCh1Ch2……...Ch24Frame 21111WordFrame 2 framing bit
114D4/SFD4 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.
115Extended 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 synchronizationFraming bits for frames 4, 8, 12, 16, 20, are set to the pattern of that the far end equipment synchronizes on.
116Extended 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 ChannelThe Embedded Operation Channel is an Out-of-Band call control method used for signaling, dialing, diagnostics as well as other functions.
117Extended Superframe Extended Superframe C C C C F F F F E E E E E E E E = Embedded Operations channel bitC = Cyclic Redundancy Check bitF = Framing bitOnly 15 of the 24 frames are shown
118Extended 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.
119What is AMI and B8ZS?Alternate Mark Inversion and Binary 8 Zero Substitution are the two Line Coding formats used in North America for T1 linesThe purpose of Line Coding is to maintains synchronization by ensuring that no more than 7 consecutive “0’s” are transmitted within a DS0.
120Signaling Formats Unipolar Signaling Bipolar Alternate Mark Inversion Used internally within most DTE equipment such as the KX-TD500 and computersBipolar Alternate Mark InversionT1 lines utilize this type of signaling format+5 v0 v+3 v0 v-3v
121AMI Line CodingAMI 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
122AMI Line Coding DTE Sends CSU set for AMI sends 0 0 0 0 0 0 0 0 +5 v O v-5 vDTE Sends+5 vO v-5 vCSU setfor AMIsends
123B8ZS Line CodingBinary 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
124B8ZS Line Coding DTE Sends CSU set for B8ZS sends 1 0 0 0 0 0 0 0 0 +5 vO v-5 vDTE SendsPrevious WordB B+5 vO v-5 vCSU setfor B8ZSsendsB = Bipoalar Violation
