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.
