Command Purpose
Step 1
Router(config)# controller T1 controller number
Enters controller configuration mode.
NEC Fusion does not support fractional T1/E1; all
24 channels must be available. If they are not
available, the configuration request will fail.
Step 2
Router(config-controller)# pri-group nec-fusion
{pbx-ip-address/pbx-ip-host-name} pbx-port number
Configures the controller to communicate with an
NEC PBX using NEC Fusion.
The range for the PBX port is 49152 to 65535. If you
do not specify a port number, the default value of
55000 will be used. If this value is already in use, the
next greater value will be used.
Step 3
Router(config-controller)# exit
Exits controller configuration mode.
