Avaya CS 1000 Series Installation And Commissioning Manual page 73

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 Avaya 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 16: S/T interface connector specification
assignment for the jack and the plug. It also shows the signal names for each interface pin at
the SILC and at the terminal.

Note:
Power Source 1 (PS1): Up to 2 Watts of power is supplied by the SILC to the terminals on
the DSL. This power is simplexed over the TX and RX pairs provided by -48 V (-40 V for
Europe) supply on the SILC. The RX pair is positive with respect to the TX pair.
Note:
Power Sink 2 (PS2) provides an optional means of powering the terminal from a common
supply in the wiring closet.
