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
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
male connector on each end. Use to connect a DS1 tie trunks in
collocated cabinets.
C6E connector cable
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
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

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).
