74 Configuring ISDN BRI hardware
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:

•
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 So-Adapter) is 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.
Table 17 "S/T interface connector specification" (page 74)
connector pin assignment for the jack and the plug. It also shows the
signal names for each interface pin at the SILC and at the terminal.
