Connecting a Paging
Amplifier
Connect the paging device to the paging connector on front of the NBX
100 Network Call Processor. See the paging amplifier instructions for
more information.
The paging connector on the network call processor is an RJ11 connector.
It is a line-out, 600 ohm audio interface with a dry contact closure for use
with an external paging amplifier.
For information about how to page from a Business Telephone, see
“Paging” in the
NBX Business Telephone User’s Guide
.
Configuring
Routing Devices
If you have a low-bandwidth device on the LAN, such as an ISDN router,
you must update the device’s routing table to filter NBX 100 multicast
addresses. The NBX 100 uses Ethernet multicast addresses to implement
some system features, such as paging and conferencing, and these
multicast transmissions can overwhelm a low-bandwidth link.
If you have Business Telephones connected to the network through a
low-bandwidth link, you can configure them so that they do not generate
multicast traffic. For more information, see “Low-bandwidth Telephony”
in the
Administrator’s Guide
. You must still filter multicasts to ensure that
multicasts generated by other NBX 100 devices are not propagated
through the low-bandwidth link.
