If no tone sounds, there is a line malfunction. Ensure that
each line card is properly cabled to the PBX. See Cabling
XMU+ Line Cards on page 54.

To perform a reset

and press Enter.

Enter.

to perform this reset.

The XMU+ backs up statistics, waits until all lines have
disconnected, and then restarts.
