the Nominal status light on the front panel of the T1 board should now
turn on (solid green). If the Nominal status light does not turn on and you
have the telephone company’s T1 line connected, disconnect the T1 line
and connect a loopback connector. If the Nominal light now turns on,
contact the telephone company for assistance with the T1 line. If the
Nominal light does not turn on, contact 3Com Technical Support.
