Connecting Telephone Lines 117
Repeat steps 9 and 10. Each time that you assign an extension, the
previous extension is no longer used, and you can assign it to the
appropriate port. When you are finished:
■
The four original extensions (7258 through 7261) are assigned to the
line card ports in the same order as the MAC addresses or port
numbers.
■
The unused extension (7269) is again unused.
Connecting
Telephone Lines
After you have installed and configured the system for initial startup,
connect the telephone company lines to the analog line ports so that you
can start receiving outside calls.
Adding External
Hardware
External devices connect to the front of the NBX system. See “What
External Devices Can Connect to an NBX System?” on page 85 .
Connecting a
Music-on-Hold (MOH)
Input Device
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 NCP. The audio input should be max 2V
peak to peak.
Adjusting Music-on-Hold (MOH) Volume
The NBX 100 and V5000 have an external control for adjusting the MOH
volume. For other NBX platforms, use the volume control on the external
MOH device.
To adjust the volume of music on hold on an NBX 100 or V5000:
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.
Connecting a Paging
Amplifier
Connect the paging device to the paging connector on the front of the
NCP. 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
NBX Telephone Guide .
