Equipment and Rear Access Cable Installation
Issue 9 October 1998
2-11
NOTE
:
DS3/EC-1 cable options are listed in Tables 2-2 and 2-3. There are some
configurations of Releases 11 and 13 that require installation of a cable on
the front panel of BBG19 DS3 circuit packs. The connection to these circuit
packs is discussed in this section and in the section on circuit pack installa-
tion.
NOTE
:
The DS3/EC-1 cables used are dependent on the equipment the
DDM-2000 OC-3 will connect to (FT-2000, DACS IV-2000, DACS III-2000,
or DSX-3), the cable length, and the number of function groups equipped
with DS3/EC-1 circuit packs (2 or 6).
NOTE
:
The six conductor cable (1735006A) provides three DS3/EC-1 IN and three
DS3/EC-1 OUT cables to accommodate the maximum number of DS3/EC-
1 function groups that can be equipped in one shelf. The two conductor
cable (734A, 735A) provides one DS3/EC-1 IN and one DS3/EC-1 OUT
cable to accommodate a pair of DS3/EC-1 cables for one function group.
NOTE
:
DS3/EC-1 cables come in a fixed length of 150 feet or they can come in a
fixed length specified by the customer. All the cables come with a connec-
tor on one end and are loose on the other end. Connectors that were put
on in the factory should not be altered.
NOTE
:
Caution:
Cables going to the front of BBG19 DS3 circuit packs (Releases
11 and 13) must be longer than those going to the backplane. There must
be enough additional length to take the cable from the blackplane over the
baffle below the shelf and up to the front of the BBG19. These cables, ED-
8C724-22, Groups 37 and 38, have right angle connectors for the connec-
tion to the circuit packs. Group 37 cables are 150 feet long and are pre-ter-
minated at both ends. Group 38 cables are terminated at the circuit pack
end, have variable length up to 250 feet, and, after cutting to length, must
be terminated with a straight connector at the end away from the circuit
packs. The far-end connector is KS23558L16. Additionally, there are a
clamp and screws to secure and ground the cable to the shelf front. Four
cables, connectors, clamp and screws will be delivered when ED-8C724-
22 is ordered.
NOTE
:
Cutting the DS3/EC-1 cable to a shorter length and reterminating (reat-
taching a connector on the end that has been cut) may result in cable qual-
ity substandard to that of factory DS3/EC-1 cable and subsequent service
outages may occur. If cables must be reterminated, use the correct con-
nector and proper crimp tool.
