Procedure 21
Connecting the terminating resistor to the SILC DSL
Plug the end of the SILC DSL to the RJ-45 jack on the terminating resistor
(A0378866) resistor.
Connecting the ISDN BRI terminals
ISDN BRI terminals are connected to DSLs using modular cables not longer
than 10 m (33 ft) with RJ-45 type plugs on each end. One end of the cable is
plugged into the terminal, and the other end is plugged into the telephone
outlet.
All terminals must be compatible with the system and comply with one of the
following protocols for ISDN BRI terminals:
• ETSI NET-3
• INS NET-64
• NUMERIS
• ANSI standards
Contact your Nortel Networks representative for the latest list of compatible
terminals.
To connect 1TR6 terminals, an ETSI NET-3 to 1TR6 protocol converter is
required. A terminal adapter (the S o -Adapter) has been specifically designed
to interface with the ISDN BRI DSL and the 1TR6 terminals. Its main
function is to convert 1TR6 protocol, sent from the 1TR6 terminal into the
ETSI NET-3 protocol required for ISDN BRI.
S/T interface specification
The S/T interface uses an 8-conductor modular cable terminated with an 8-pin
RJ-45 type plug. An 8-pin RJ-45 type jack located on the terminal connects
the terminal to the DSL using this modular cable.
