Connecting The Terminating Resistors - Avaya CS 1000 Series Installation And Commissioning Manual

Connecting the terminating resistors

DSLs require that a terminating resistor be connected at the end of each loop. See Avaya ISDN
Basic Rate Interface Feature Fundamentals (NN43001-580) for engineering rules and
locations of terminating resistors. The end of the S/T interface loop has an RJ-45 jack to plug
in the telephone cable. Plug the terminating resistor into the RJ-45 jack, and then plug the
telephone cable into the terminating resistor.
Note:
For every port there is one loop with only one terminating resistor per loop. Each loop can
support a maximum of eight telephones.
