Connecting 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 the system. For a list of
compatible terminals, refer to the
ISDN Basic Rate Interface: Features
(553-3001-380) .

Procedure 10
Connecting the ISDN BRI terminals to the DSL
1 Plug 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.
2 For 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.
3 Program 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: Features (553-3001-380).
4 Repeat steps 1 and 3 for each terminal to be connected.
End of Procedure
Connecting the terminating resistors
DSLs require that a terminating resistor be connected at the end of each loop.
See
ISDN Basic Rate Interface: Features (553-3001-380) 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
