Nortel Networks NN43001-318 manual Interface connector specification RJ45 jack

Installation procedures 75

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 So-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.

Table 17 "S/T interface connector specification" (page 75) shows the 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.
