Early model 3Com Telephones support an earlier version of the LUI utility
that has a slightly different menu. For information about this earlier
version of the LUI utility, see your NBX Voice-Authorized Partner or a
version of the
NBX Administrator’s Guide from a release prior to release
R4.3.
To start the LUI utility:
1 Cycle power to the telephone by disconnecting and then reconnecting its
power connector, and then access the LUI menu options (see
step 2 )
before the telephone finishes its download of code from the Call
Processor).
For telephones that use a powered Ethernet cable instead of a power
adapter, disconnect and then reconnect the Ethernet cable.
You do not need to cycle power to 3101B and 3102B Business
