Page 142: Connecting The Control Unit To The Network Interface
Connecting the Control Unit to the Network Interface 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. CAUTION: The telephone company is responsible for providing appropriate protection for central office trunks.
Page 143: Wiring
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.
Page 144: Connecting The Control Unit To The Network Interface
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. See Appendix A, “System Numbering Forms.” Also, you may need to know the interface codes for network facilities. These codes are shown in Table 4–2, by trunk type and adapter type.
Page 145 Wiring When constructing wiring fields between the network interface and the control unit, you must order hardware as individual parts. Do not use Interconnect Wiring or Systimax wiring kits. RJ21X Interface The RJ21X network interface has a female 50-pin (25-pair) amphenol connector, as shown in Figure 4–1.

Page 149: Using The D-Impact Tool To Seat The Conductors
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.
Page 150 Wiring 8 Test the central office trunks for proper connection. See “Testing Trunks,” later in this chapter, for instructions. 9 Label the network interface jacks, control unit module jacks, termination blocks, and D2R cords. See “Labeling Trunks,” later in this chapter, for instructions. 10 For each trunk, plug one end of a D2R cord into the designated jack on the termination block and the other end into the line/trunk jack on the proper control unit module.
Page 151: Rj11 And Rj14 Interfaces
Wiring RJ11 and RJ14 Interfaces RJ11 and RJ14 interfaces are connected to the control unit similarly. However, note the following differences: RJ11 connects one central office trunk per jack. RJ14 connects two trunks per jack. Plug a 267C-type adapter into each RJ14 jack. You need D2R cords for RJ11 jacks.
Page 152 Wiring 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. If you cannot avoid using the Brand-Rex Quad cable, reverse the tip and ring leads at the E66 block to correct the mismatch.
Page 153: Testing Trunks
Testing Trunks CAUTION: Be careful not to connect tie trunks to GS, LS, 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.
Page 154 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.
