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
system MUST BE the terminating element of the bus and any other terminating resistor MUST BE
removed.
Connection with T0/S0 Forwarding
In the event of a loss of tension or PowerCPU malfunction, the ISDN-EFM box allows a T0
access to be forwarded directly to a S0 station.
Caution:
The AFU-1 board (daughter board of the PowerCPU board) must obligatorily be fitted to detect the
absence of power.
