Providing Backup Capability
If the E1 network fails, the E1 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 (Cust2) set of customer-defined configuration
options. The Paradyne 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.
