Connecting the Control Unit to the Network Interface 4 The way you connect the control unit to the network interface depends on the type of network interface that is installed. While there are many ways you can do this, the methods discussed in this chapter are usually best.
Wiring Wiring The local telephone company should have installed the network interface (the central office trunks) already. Before you install the system, verify that the network interface is the proper type and that it is within 25 ft. (7.6 m) of the control unit.
Wiring NOTE: If you need to connect the trunk cords differently from the instructions on the system forms, record each change on Form 2c, System Numbering: Line/Trunk Jacks.
Wiring RJ21X Interface The RJ21X network interface has a female 50-pin (25-pair) amphenol connector, as shown in Figure 4–1. To connect the RJ21X interface to the control unit, you must build a wiring field between the RJ21X interface and the control unit using a 66-type block (RJ21).

Wiring 3 If necessary, repeat Steps 1 and 2 for a second column. 4 Run the 25-pair amphenol cable on the RJ21X interface to the termination blocks. If more length is needed, use an A25D male-connector, single-ended, 25-pair, nonplenum cable. 5 Mount the D-rings to properly dress the wires, as needed.
Wiring 8 9 10 Test the central office trunks for proper connection. See “Testing Trunks,” later in this chapter, for instructions. Label the network interface jacks, control unit module jacks, termination blocks, and D2R cords. See “Labeling Trunks,” later in this chapter, for instructions.
Wiring RJ11 and RJ14 Interfaces note the following differences: ■ RJ11 connects ■ RJ14 connects one central office trunk per jack. two trunks per jack. RJ11 and RJ14 interfaces are connected to the control unit similarly. However, Plug a 267C-type adapter into each RJ14 jack.
Wiring 1 2 3 4 CAUTION: Incorrect wiring can damage the ports and cause them to stop functioning. Make sure you use the proper cords. For all GS/LS modules, do the following: ■ Use a D2R cable from an RJ11. ■ Do not use the Brand-Rex Quad cable from an E66 block.
Testing Trunks CAUTION: Be careful not to connect tie trunks to GS, LS J or DID ports. Since all the jacks on the termination block are 8-wire jacks, it is possible to interchange tie trunk wires with GS, LS, or DID wires accidentally. RJ48C/X Interface The RJ48C/X interface terminates a DS1 trunk at the customer’s premises.
Testing Trunks 2 If you find a central office trunk that does not have dial tone, check for a bad adapter or loose connection. If adapters and wiring are in working order but you still do not hear a dial tone, notify the AT&T Service Center acting as the customer’s agent.

Preparation for Hardware Maintenance Disconnecting AC Power To disconnect the AC power, see Figure 1-6, and follow the steps below. 1 Disconnect the AC power to each auxiliary power unit by unplugging the power cord from the wall outlet. 2 Disconnect the AC power to each carrier by unplugging the power cord from the wall outlet.
Maintenance Strategy Maintenance Strategy The maintenance strategy presented in this section is only a guideline, not a fixed procedure. Refer to Figure 1-7 whenever you are uncertain as to how to proceed. As you become more experienced with maintaining and troubleshooting the system, you will most likely develop your own strategy.
Maintenance Strategy Trouble Reports System trouble can be reported in two ways: ■ By users ■ By system alarms (permanent errors) Automatic Tests The system performs ongoing maintenance automatically by running tests that : Monitor the status of equipment.
Maintenance Strategy If a software installation or upgrade is taking place, a blinking character is displayed to indicate the status of the procedure. See "Forced Installation of System Software” in Chapter 4 for more information.
Maintenance Strategy Warm Start A loss of power for less than 250 ms can cause a warm start. If this occurs, calls in progress are not dropped, but calls in the process of being connected may be dropped. Considerations ■ ■ Power interruptions of less than 100 ms usually do not affect the system.
Maintenance Strategy Frigid Start (System Erase) CAUTION: All system programming is erased. When you perform a frigid start (System Erase), all calls are dropped, and the system configuration information is erased. All system memory must be reinitialized, including system programming.
Maintenance Strategy Isolating the Trouble You can isolate any problem to one of the following areas: ■ Telephone ■ Control unit ■ Central office NOTE: If you change the jack assignment of any telephone, be sure to record the extension jack change on Form 2a, System Numbering: Extension Jacks.
Maintenance Strategy 1 Check the permanent errors. 2 If errors still exist, check the transient errors. 3 Check the last 10 errors whenever you want to review the 10 most recently recorded errors-either permanent or transient.
Maintenance Strategy Once you receive that information, use any maintenance or system programming feature that may lead to the root of the problem. See “Access Log for Maintenance and System Programming” in Chapter 2 for additional information. See System Programming for information about system programming and the Inspect function.
Unit Loads Check the Trunks Troubleshoot the trunks that are connected to the control unit. See Chapter 5, “Central Office Problems.” Check the Central Office If the error logs indicate the centra.
Unit Loads Only the telephones and adjuncts that connect to the analog and digital ports on the control unit require unit load calculation. Do not include any equipment with its own power supply (for example, an answering machine) in the unit load calculation.
Unit Loads Auxiliary Power Units The power supply provides 54 unit loads (102.6 watts) to each carrier. If the unit load requirement for a carrier exceeds 54 (102.6 watts), an auxiliary power unit is needed to allow that carrier to support an additional 27 unit loads (51.
Error Logs, Access Logs, and System Inventory 2 As described in “Maintenance Strategy” in Chapter 1, much of your troubleshooting relies on the error logs and the access log, for maintenance and system programming. Both of these maintenance features are described here in detail.
