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

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).
