Connect the ISDN BRI terminals to the DSL

ISDN BRI terminals are connected to DSLs using modular cables up to 10 meters (33 feet) long, with RJ-45 plugs on each end. One end of the cable plugs into the terminal and the other end plugs into the wall outlet.

Note: All ISDN BRI terminals should comply with CCITT, ANSI, ETSI NET-3, INS NET-64, National ISDN, 1TR6, Numeris VN2, and D70 standards for terminals, and be compatible with Meridian 1. For a list of compatible terminals, refer to the ISDN Basic Rate Interface: Product Description (553-3901-100).

Figure 9 illustrates a terminal connection to the S/T interface; Figure 10 illustrates a network termination (NT1) connection to the U interface.

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 SPID and 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: Administration (553-3901-300).

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

Connect the terminating resistors

DSLs require that a terminating resistor (Part Number A0378866) be connected at the end of each loop. See ISDN Basic Rate Interface: Product Description (553-3901-100),for engineering rules and locations of terminating resistors. The end of the S/T interface loop has a RJ-45 jack to plug in the telephone cable. Plug the terminating resistor into the RJ-45 and then plug the telephone cable into the terminating resistor. Note that for every port there is one loop with only one terminating resistor per loop. Each loop may have up to eight telephones.
