3.54.1.1.1 DESCRIPTION
All the external calls from the digital network (T0 or T2 accesses) intended for the stations in
the installation can be re-routed to a destination on the network.
First of all, the system manager will have subscribed to "Call Forwarding Unconditional" (CFU)
with the network operator.
There are two subscription versions:
- fixed forwarding: the forwarding destination is programmed into the public exchange
carrier and is always the same.
- variable forwarding: the forwarding destination is specified at activation of the service and
can thus be different at each activation.
Note:
PCX forwarding by CFU is only possible with a point-to-point link (ETSI).
Access to the service is controlled by a password, either:
- in the public exchange: the password given by the exchange carrier is retransmitted to the
public exchange on activation of forwarding.
- in the system: the password is that of the system operator and is not retransmitted to the
public exchange.
To configure the service in the system (so that it correctly transmits the PCX forwarding
activation request) the configuration in the public exchange must take account of the
installation's digital links. These can be of 3 types:
- configuration of type 0: all the digital links connecting the installation to the public
exchange are configured into a single "group" (equivalent to a trunk group) in the public
exchange.
- configuration of type 1: the installation is connected to the public exchange by "groups" of
links and isolated digital links.
- configuration of type 2: the installation is connected to the public exchange by several
"groups" of digital links.
