3 Integration Examples for 4 & 8 Port Rack Mount

There are three basic environments that the Elite Gateway* can be
applied to. They are described in the following sections.
3.1 Application A: FXS
Application A has two possible connections. The A-1 connection
shows the connection between the gateway and telephone set
(POTS) or FAX machine. The FXS module is used in the A-1
connection. The A-2 connection on the right hand side is used to
connect the gateway and PBX that has the Central Office (CO)
trunk interface. FXS is also used in this connection. The telephone
sets connected to the PBX can be either POTS or digital telephone
depending upon the PBX capability.
3.2 Application B: FXS/FXO Combination
Application B has three possible connections. The B-1 connection is
a normal trunk connection between the CO switch and a PBX. The
B-2 connection is identical to the A-1 connection mentioned in
Application A. The B-3 connection is used to connect the PBX and
gateway through the internal analog lines provided by the PBX. In
this case, the FXO module has to be used and the FXO ports will
serve the same roles as the analog telephone sets.
Note: If the PBX used in the B-3 connection is a digital type an
analog terminal adapter is needed to provide an analog interface to
the FXO module.
In this application the caller in the B-2 connection can use the
gateway through its FXS module to communicate with the party on
the other end of the B-3 connection. The phone call is forwarded
through the FXS module in the B-2 Gateway and is received by the
FXO module in the B-3 gateway, which is connected to the PBX,
which will then switch to the dedicated terminal.
The same caller can also use the feature that the Gateway provides
to redial the local number through the PBX to the public switch in
