x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address idle-timer minutes
The command configures the maximum idle time for SVC associated with an address
mapping.
Step 5 Run:
x25 vc-per-map count
The command configures the maximum number of SVCs associated with all address
mappings on the interface.
Step 6 Run:
x25 map { compressedtcp protocol-address | ip protocol-address }* x121-address
x.121-address vc-per-map count
The command configures the maximum number of SVCs associated with an address mapping.
Step 7 Run:
x25 receive-threshold count
The command configures the packet acknowledgment value.
Step 8 Specify the number of closed user group (CUG).
z
Run the x25 call-facility closed-user-group number command to specify the number of
the CUG.
z
Run the x25 map { compressedtcp protocol-address | ip protocol-address } *
x121-address x.121-address closed-user-group number command to configure the X.25
mapping.
Step 9 Configure flow-control parameters when a call is initiated:
z
Run one of the following commands to configure packet size.
− x25 call-facility packet-size input-packet output-packet
− x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address packet-size input-packet output-packet
z
Run one of the following commands to configure window size.
− x25 call-facility window-size input-window-size output-window-size
− x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address window-size input-window-size output-window-size
Step 10 Run one of the following commands to configure reverse charging when a call is initiated.
z
x25 call-facility reverse-charge-request
z
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address reverse-charge-request
Step 11 Run one of the following command to receive calls with reverse charging requests.
z
x25 reverse-charge-accept
z
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address reverse-charge-accept
Step 12 Run one of the following commands to configure threshold when a call is initiated.
