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 miscellaneous power supplies.
These cables provide the -48V/-48VRTN and the +20Hz/-20Hz ringing
connections to the power supplies. See Figure 1-1.
Step 1:
Locate the test head's 955-7000xxx037 and 955-7000xxx038 dangler
cables.
Step 2:
Mate the P12 connector of the 955-7000xxx037 cable with J12 on the
test head and route it to the battery power supply.
Step 3:
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 4:
Mate the P15 connector of the 955-7000xxx038 cable with J15 on the
test head and route it to the ringing power supply.
Step 5:
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 6:
Use tie-wraps to secure the cables.
Step 7:
If connected to a fuse panel, equip the test head battery fuse position
with a 5 amp fuse.
Step 8:
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
NOTE:
If there is a cable connected to J44 of the ARM shelf that has been
selected to provide control signals to the test head, the ED7C723-37,
Group 30 cable assembly is required.
The following steps are performed when the 955-7000xxx035 or the 955-7000107
cable is provided to obtain control signals from the
SLC
-2000 Access System
ARM shelf.
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.
