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.

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 m).
DS1 tie trunks using T1 channel-service unit
on page 105 shows a DS1 tie trunk connected to
an external T1 channel-service unit (CSU). An enhanced 120A2 integrated channel-service unit (ICSU)
can be used in place of an external T1 CSU. The CSU or ICSU interfaces the DS1 tie trunks with the
1.544-Mbps digital facility. Contact your Avaya representative for maximum cabling distances.
