Digital Tie Trunk Wiring
DS1 Tie Trunk Example
Digital Signal Level 1 (DS1) tie trunks provide a 1.544 Mbps (T1) or 2.048 Mbps (E1) digital
data service between two collocated configurations or between the configuration and a data
network.
See these examples:
• ‘‘Collocated DS1 Tie Trunks’’ on page 112
• ‘‘DS1 Tie Trunks Using T1 Channel Service Unit’’ on page 113
For cable descriptions, see
• ‘‘DS1 Cables’’ on page 114
• ‘‘Pinout of C6F Cable’’ on page 114
Collocated DS1 Tie Trunks
Two DS1 tie trunk circuit packs can be in collocated configurations. A DS1 Tie Trunk circuit
pack in one configuration can be connected to a DS1 in another configuration. A C6D cable can
be used if the distance is less than 50 feet (15.2 m). If the distance is between 50 feet (15.2 m)
and 1310 feet (399 m), use a C6E cable.
NOTE:
The maximum distance between cabinets is 1310 feet (399.3 m).
