Cable examples for tie trunk connectivity
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 — 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.
■ C6D connector cable — 50-foot (15.2 m) shielded cable with a 50-pin
male connector on each end. Use to connect DS1 tie trunks in collocated
cabinets.
■ C6E connector cable — 100-foot (30.5 m) shielded cable with a 50-pin
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 — 50-foot (15.2 m) shielded cable with a 50-pin
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 requiring
hardwired connections. See Table 1-15 for a pinout.
DS1 tie trunks between collocated systems
Two DS1 tie trunk circuit packs can exist 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).
