WAN failover

The router hardware simplifies WAN failover as well as future management integration through
the internal serial connector. The router provides support for WAN failover on all BCM50
platforms with M222/252 routers.
WAN failover allows calls that experience issues using the WAN link to continue over the soft
modem or LAN or ISDN.

Integrated Services Digital Network Basic Rate Interface dial-up support

The BCM50 requires a data layer over the channelized Integrated Services Digital Network
(ISDN) for remote management dial-up over Basic Rate Interface (BRI). Support is available for
remote management over BRI over the integrated BRI CDC or BRI MBM configured for ISDN
support. Support is available for all on-demand and scheduled management tasks, are such as CDR
collection, backup and restore, software updates, and log collection.
