Test Head Installation
Test Head Interconnections
General
The cables that were installed in previous steps will now be connected to the
external equipment. The connection may be direct or employing other cables.
Power and Ringing Cables
The following steps are performed when the 955-7000xxx037 and the
955-7000xxx038 cables are provided to obtain battery and ringing voltages from
the power supplies or a miscellaneous fuse panel.
These cables provide the -48V/-48VRTN and the +20Hz/-20Hz ringing
connections to the miscellaneous power supplies. See Figure 1-1.
Step 1: Locate the 955-7000xxx037 and the 955-7000xxx038 cables from the
test head and route them to the power equipment. Use tie-wraps to
secure the cables.
Step 2: Connect the leads in accordance with the associated figures for the
P12 connector of the 955-7000xxx037 cable (See Figure 1-2) at the
battery supply or an assigned fuse position for the test head.
Step 3: Connect the leads in accordance with the associated figures for the
P15 connector of the 955-7000xxx038 cable (See Figure 1-3) at the
ringing supply or an assigned fuse position for the test head.
Step 4: If connected to a fuse panel, equip the test head battery fuse position
with a 5 amp fuse.
Step 5: If connected to a fuse panel, equip the test head ringing fuse positions
with a 1/2 amp fuse each for the positive and negative ringers.
Control Link Cables
These cables are the control link with the test head. See Figure 1-1 for the cabling
and Figure 1-4 for the signals on J44 of the ARM shelf.
NOTE
:
The lead designations for J44 of the
SLC-2000 Access System ARM shelf
and the test head are shown in Figure 1-4 to indicate that the connector is
used for more than one purpose and that signals may appear on the con-
nector that may not be required for a specific application.
Step 1:
Locate the test head's 955-7000107 or 955-7000xxx035 dangler cable
(RS232/MTAU) that was installed previously.
Step 2:
Locate the test head's 955-7000010108 cable.
