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 system multicast
addresses. The NBX system uses Ethernet multicast addresses to
implement some system features.
If you have telephones connected to the network through a
low-bandwidth link, such as an ISDN connection, you can configure them
so that they do not generate multicast traffic (
Table 18
). For more
information, see the
NBX Administrator’s Guide
. You must still filter
multicasts to ensure that multicasts generated by other NBX devices are
not propagated through the low-bandwidth link.
An NBX 100 system does not support Conference channels 4 through 11.
