Installation and Safety Guide

Connection to ISDN network

Ports for the connection of other apparatus

The following interfaces normally operate at SELV (Safe Extra Low Voltage) levels:

Asynchronous (console) ports

Ethernet ports

G703 ports

Synchronous ports

Note SELV is a secondary circuit whose voltages do not exceed a safe value under normal operating conditions and under single fault conditions. Under normal operating conditions the voltages do not exceed 42.4 V peak AC or 60 V DC.

TNV1

The following interfaces are Telecommunications Network Voltage (TNV1) circuits, which operate normally within the limits of SELV:

BRI ports for connection to ISDN Basic Rate telecommunications networks

PRI ports for connection to ISDN Primary Rate telecommunications networks

E1/T1 ports for connection to E1/T1 services

Note A TNV1 circuit is a circuit which under normal operating conditions does not exceed the limits for SELV and on which overvoltages from telecommunication networks are possible.
