Ports Assigned to the Expansion Unit

8- Ports Assigned

The exchange line (CO) and telephone (ST) ports are assigned automatically when the system is powered on.
The ports assigned depend on the configuration of the system before the new expansion unit was installed.
If you have installed more than one expansion unit then the system will assign port numbers to the units in the
following order:
Expansion unit 1 then Expansion unit 2
You can confirm the ports assigned with Program 10-03-01. Refer to 'Configure the Expansion Units' for
instructions to access configuration mode.
