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 169

‘‘Pinout of C6F Cable’’ on page 171
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 meters)
and 1310 feet (399 meters), use a C6E cable.
NOTE:
The maximum distance between cabinets is 1310 feet (399 meters).
DS1 Tie Trunks Using T1 Channel Service Unit
The T1 Channel Service Unit (CSU) interfaces the DS1 tie trunks with the 1.544 megabits per
second digital facility.
