36Installing ISDN BRI hardware

Procedure 10

Connecting the ISDN BRI terminals to the DSL

Step Action

1Plug one end of the modular cable into the ISDN BRI interface connector on the terminal and the other end of the modular cable into the wall outlet.

2For an SILC S/T interface terminal with an optional auxiliary power source, plug the power source into the wall outlet, then plug the cable into the power source’s RJ-45 jack. This power source must supply power only to the local ISDN BRI terminal, not back into the DSL through the RJ-45 wall outlet. The power adapter is supplied with the terminal.

3Program the terminal parameters, such as the Supervisor Position ID (SPID) and Static Terminal Endpoint Identifier (TEI), as required by the type of terminal. For detailed information pertaining to this procedure, refer to the section "Initialize ISDN BRI terminals", found in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

4Repeat steps 1 and 3 for each terminal to be connected.

Connecting the terminating resistors

DSLs require that a terminating resistor be connected at the end of each loop. See 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.
