4.2.1.4.2 Connecting analog terminals

The terminals are equipped with a cable and a self-acting switch that plugs into the wall

socket. Each terminal is connected up with a pair of 0.5 or 0.6-mm diameter wires (the

maximum distance with 0.5-mm cabling is 1.3 km).

4.2.1.5 CONNECTION TO THE PUBLIC NETWORK

4.2.1.5.1 Digital public network via T0 access (or DLT0 private network)

The Alcatel-Lucent OmniPCX Office Communication Server system can be installed near the

digital network termination or at a certain distance (up to 350 m), as required.

Connection without T0/S0 forwarding

Caution:

In T0 Point-to-Point installations, the Alcatel-Lucent OmniPCX Office Communication Server sys-

tem MUST BE the terminating element of the bus and any other terminating resistor MUST BE re-

moved.

Connection with T0/S0 forwarding

In the event of a loss of tension or CPU malfunction, the ISDN-EFM box allows a T0 access to

be forwarded directly to a S0 station.
