CONFIGURING ALTERNATE ACCESSES

X.25 Accesses

PERMANENT VIRTUAL CIRCUIT INFORMATION

Note: SVCs and PVCs are specified in the X.25 Logical Channel Assignments section of the configuration. However, PVCs require additional configuration, which is done in this section.

1.Follow the onscreen instructions to begin the configuration of a virtual circuit.

Note: Default values are configured for each PVC when an access is newly created. You are given the opportunity to modify the PVC configuration (steps 2 through 7). If you are unsure of what to change, use the default configuration. Note that the packet sizes are limited to 128 bytes for D-channel configurations.

2.Enter the Logical Channel Number (LCN) that is to be used for this PVC. LCN values are obtained from the PPSN carrier.

3.Enter the nonstandard default transmit window size.

4.Enter the nonstandard default receive window size.

5.Select the nonstandard default transmit packet size.

6.Select the nonstandard default receive packet size.

7.Select the nonstandard default transmit throughput class.

8.Select the nonstandard default receive throughput class.

9.After all of the above information has been entered for your PVC, repeat the above steps to add the rest of your PVCs (up to the maximum number of PVCs)
