DS1 Tie Trunk Example

DS1 tie trunks provide a 1.544 Mbps digital data service between 2 collocated systems or between the system and a data network using T1 carrier facilities. DS1 tie trunk circuit packs provide connection capability to the DS1 facility.

The following cables can be used to connect DS1 tie trunk circuit packs to DS1 digital facilities:

■C6C connector cable (comcode 104307327) — 50-foot (15.24 m) shielded cable equipped with a 50-pin male connector on 1 end and a

15-pin male connector on the other end. Use this cable to connect a DS1 tie trunk circuit pack to a Channel Service Unit (CSU).

■C6D connector cable (comcode 104307376) — 50-foot (15.24 m) shielded cable equipped with a 50-pin male connector on each end. Use this cable to connect a DS1 tie trunks in collocated Single-Carrier Cabinets.

■C6E connector cable (comcode 104307434) — 100-foot (30.48 m) shielded cable equipped with a 50-pin male connector on 1 end and a 50-pin female connector on the other end. Use this cable as an “extension” cable between the DS1 tie trunk circuit pack and other connector cables.

■C6F connector cable (comcode 104307475) — 50-foot (15.24 m) shielded cable equipped with a 50-pin male connector on 1 end and a

3-inch (7.62 cm) stub on the other end. Use this cable to connect the DS1 tie trunk circuit pack to channel multiplexers requiring hardwired connections. See Table 5-1 for a pinout of the C6F cable.

Collocated DS1 Tie Trunks

Connection to 2 TN722B DS1 Tie Trunk circuit packs in collocated systems can include a C6D cable for distances up to 50 feet (15.24 m). For distances over 50 feet (15.24 m) and up to 1310 Feet (399.3 m) maximum, use C6E cables.
