Dial Backup Implementation Notes
This chapter describes Bay Networks implementation of dial backup service.
Most of these notes apply only to circuit backup; that is, they apply only to a
primary Bay Networks Standard, PPP, or Frame Relay PVC. Data compression is
the only feature that you can use with circuit and link backup.
Data Compression
Site Manager allows you to configure Bay Networks proprietary data compression
protocol, WCP, over any PPP or Frame Relay primary and backup circuit.
Enabling data compression improves bandwidth efficiency by eliminating
redundant strings in data streams. This, in turn, improves network response times
and yields line-cost savings.
To implement data compression, you must enable WCP on the leased circuit that
you selected before configuring the backup pools.
For more information about data compression, see Configuring Data Compression
Services.
