4. Feature-Specific Configuration

PVC Backup Over the Network Interface

Generally, backup can be performed on the network interface’s frame relay link using a backup PVC, as well on an ISDN link; the unit does not have to have the ISDN DBM feature.

In this case, create a DLCI Record on the network interface that will be used for backup, then modify the PVC Connections or Management PVCs to add the alternate destination.

Setting Up Back-to-Back Operation

Using this special feature, you can set up two FrameSaver units that are connected back-to-back without frame relay switches between them, as in a test bench setup using a crossover cable.

Changing Operating Mode

When setting up back-to-back operation:

νOne unit must be configured for Standard operation, which is the setting for normal operation.

νThe other unit must be configured for Back-to-Back operation so it presents the network side of the UNI (user-network interface).

Only one of the units will have its operating mode changed.

Procedure

To set up back-to-back operation:

1.On the unit to be configured for Back-to-Back operation, manually configure DLCIs; DLCIs should be configured before connecting the two units.

2.Access the Change Operating Mode screen.

Main Menu→Control→Change Operating Mode

3.Select Back-to-Back Operation, and respond Yes to the Are you sure? prompt.

4.Save the change.

Procedure

To return the unit to normal operation:

1.Return to the Change Operating Mode screen and switch back to Standard Operation.

2.Respond Yes to the prompt and save the change. The units can be reconnected to a standard frame relay network.
