Providing Backup Capability
If the T1 network fails, the DSU/CSU provides the
ability to reconfigure the unit and restore (at least
partially) priority data circuits through an external backup
device.
You can store backup configuration options in the
Customer 2 set of customer-defined configuration options.
The Enterprise MIB variable devConfigAreaCopy allows
the entire contents of one configuration area to be copied
into another configuration area via SNMP.
By cross-connecting two synchronous data ports to
each other, one port can provide a backup path for the
other. As soon as the ports are configured to be mapped to
each other, Data Set Ready (DSR) for the ports is turned
on. The external backup device can be configured to
initiate dialing when it detects the off-to-on transition of
DSR.
