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-Premises
Stations
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.

Install secondary protectors (see Table 2-B).
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.
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.
Plug connector O into the 700A Jack.
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.
Repeat procedure as required.
