INSTALLATION

Connect Cabinets to TAE Blocks

The connections between the cabinets and the TAE blocks are made using connectorized splitter cables. Make sure that each trunk group on each connecting block is connected to the correct type of CP and protected with its approved secondary protector (as shown in Table 2-B).

Central office trunks associated with emergency transfer and off-premises stations (OPSs) are not connected directly to the cabinets. If you are installing trunks that are to be used for OPS, see Off-PremisesStations in this p a r t . Also, to complete the procedure for installing trunks used for emergency transfer, you must go to Install Emergency Transfer Units (ETUS) in this part.

Connect Ground Start, Loop Start, and DID Trunks

A 3:1 connectorized splitter cable, WP90929, L1, is required to connect the 700A Jack to the cabinet for these trunks.

1.Install secondary protectors (see Table 2-B).

2.Using the cable label sheets provided (Figure 2-7),label the back of the hood of each of the connectors (1, 2, and 3) on the three legs of the splitter cable (see Note). Use an appropriate cabinet and slot number label (CAB 1 SLOT9, for example).

N o t e : If one or more of the legs contain trunks that are to be used for emergency transfer, do not label these legs. Set the legs aside and go to Install Emergency Transfer Units (HUS) in this part to complete the installation of these trunks.

3.On connector O, install labels that correspond to those used on each of the three splitter cable legs. Position the labels so that they will be clearly visible after the cable is plugged in.

4.Plug connector O into the 700A Jack.

5.Except for legs containing trunks to be used for emergency transfer, connect connectors 1, 2, and 3 to the cabinet. Connect only to ZTN76 Ground Start, ZTN77 Loop Start, or TN753 DID CPs.

6.Repeat procedure as required.
