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)

X.25 CONFIGURATION ELEMENTS

X.25 LINE CONFIGURATION ELEMENTS

LINE ID NUMBER

From the displayed list of available lines, this is the Id Number of the previously defined line that

is to be used for this X.25 connection. A line that is in use by another type of access will not be

available for use by an X.25 access.

X.25 A

CCESS NAME

The user defined name that will be used to identify this X.25 access. This name can consist of 1 to

16 non-blank, alpha-numeric characters. The X.25 access name is provided as an aid in helping to

track events occurring on an X.25 access.

OCAL DTE ADDRESS

The X.121 address to be used as the local DTE address. The X.121 address is the public data network

address assigned by your X.25 provider. The local DTE (Data Terminal Equipment) in our

application refers to the CyberSWITCH.

The data rate that applies to the line being used for this X.25 access. The configured data rate can
