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
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
Telephones.
