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:
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.

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).
