Configuring Data Compression Services

To use data compression with frame relay dial backup, you must configure

compression on both the primary and the backup circuit. The backup circuit does

not necessarily inherit the PVC configuration from the primary circuit because the

backup PVCs can have different configurations from the primary.

For further information on Bay Networks dial services, refer to Configuring Dial

Services.

Frame Relay Multiline

Multiline is a feature that enables you to configure a single circuit that consists of

one or more WAN data paths. A data path is a logical point-to-point channel; it

can be a permanent or dial-up physical line, or it can be a virtual circuit

connection. Multiline provides both increased fault tolerance and greater

bandwidth between two sites.

For more information about Bay Networks multiline, refer to Configuring WAN

Line Services.

X.25 Services

An X.25 network permits as many as 128 VCs to exist on the same physical link at

the same time. You can configure each of these interfaces individually to use data

compression or not.

X.25 PDN and DDN Services

When you use data compression on circuits that you configure for X.25 Public

Data Network (PDN) or Defense Department Network (DDN) services, you must

enable compression on both sides of the link. If you configure compression on

only one side of a PDN or DDN link, the data that travels over that link will be

corrupted.

You must also remember to enable the X.25 service record compression parameter

for each X.25 interface that you configure. For more information about this

parameter, refer to Configuring X.25 Services.
