Collocated DS1 interface trunks
Two TN464GP DS1 Interface circuit packs can be in collocated configurations. A DS1 Interface 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 meters). If the distance is between 50 feet (15 meters) and 1,310
feet (399 meters), use a C6E cable.
DS1 interface trunks using T1 channel service
unit
The T1 channel service unit (CSU) interfaces the DS1 interface trunks with the 1.544 megabits per
second digital facility.
Connect the DS1 interface trunk to a T1 CSU. See
on page 240.
Contact your Avaya representative for maximum cabling distances for the 3127 series CSU or the 120A
ICSU.
