1
Before installing the DS1 Interface circuit pack, set the option switches according to
Chapter 2,
“Completing Installation and Cable Pinouts”
.
2
Install cross-connect jumpers to connect the pins from the digital trunk circuit pack to appropriate
pins on the external digital trunk.
3
Administer the DS1 Interface circuit pack on the DS1 and Trunk Group Screens. See
Administrator’s Guide for Avaya Communication Manager.
DS1 Tie Trunk Example
DS1 tie trunks provide a 1.544 Mbps (T1) or 2.048 Mbps (E1) digital data service between 2 collocated
systems or between the system and a data network. The following cables can be used:
•
C6C connector cable
—
50-foot (15.2 m) shielded cable with a 50-pin male connector on 1 end
and a 15-pin male connector on the other end. Use to connect a DS1 tie trunk circuit pack to a
Channel Service Unit.
•
C6D connector cable
—
50-foot (15.2 m) shielded cable with a 50-pin male connector on each
end. Use to connect a DS1 tie trunks in collocated cabinets.
•
C6E connector cable
—
100-foot (30.5 m) shielded cable with a 50-pin male connector on 1 end
and a 50-pin female connector on the other end. Use as an “extension” cable between the DS1 tie
trunk circuit pack and other connector cables.
•
C6F connector cable
—
50-foot (15.2 m) shielded cable with a 50-pin male connector on 1 end
and a 3 inch (7.62 cm) stub on the other end. Use to connect the DS1 tie trunk circuit pack to
channel multiplexers requiring hardwired connections. See
Table 12
for a pinout.
Collocated DS1 Tie Trunks
Two DS1 tie trunk circuit packs can be in collocated systems. A DS1 tie trunk circuit pack in 1 system
can connect to a DS1 tie trunk in another system. Use a C6D cable if the distance is less than 50 feet
(15.24 m). If the distance is greater than 50 feet (15.24 m), use a C6E cable.
NOTE:
The maximum distance between cabinets is 1310 feet (399.3 m).
