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)
