After you have installed and configured the system for initial startup,
connect the telephone company lines to the line card ports so that you
can start receiving outside calls.
External devices connect to the front of the Call Processor. See
External Devices Can Connect to an NBX System?"
Use a patch cord with phono-type connectors (stereo or mono) to
connect line level audio from any audio device that has a line-out jack to
the MOH jack on the front of the Call Processor.
Adjusting Music-on-Hold (MOH) Volume
To adjust the volume of music on hold (MOH):
1 Use a nonferrous (plastic or aluminum) adjustment tool to adjust the
volume control on the front of the Call Processor to about mid-range.
2 Use a 3Com Telephone to call another extension, and have the person
put you on hold.
3 While listening to the music, adjust the volume control on the
music-on-hold input device.
Connect the paging device to the paging connector on the front of the
Call Processor. See the documentation for your paging amplifier for
information about that device. For information about how to page from a
telephone on the NBX system, see "Paging" in the "Getting More From
Your Telephone System" chapter in the NBX Telephone Guide.
The paging connector on the Call Processor is an RJ-11 connector. It is a
line-out, 600 ohm audio interface with a dry contact closure for use with
an external paging amplifier
