It is recommended that the ports be connected as follows:
•
CO Lines: Begin with port 1 and move up.
•
Telephone Handsets: Begin with port 8 and move down.
The Power Fail Phone port may be used to connect an analog phone device that is operational in the event
that the Port Expander loses power, if it loses its network connection to the Allworx server, or if some other
hardware failure occurs. When in this condition, calls using an analog phone connected to the Power Fail
Phone port will be routed to the first outside phone line port (port 1).
Surge protection is provided internally on all telephony interfaces.
Under normal operation of the unit, the port LEDs will appear as listed, below.
