z
x25 call-facility threshold in out
z
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address threshold in out
Step 13 Run one of the following commands to carry transmitting delay request in a call.
z
x25 call-facility send-delay milliseconds
z
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address send-delay milliseconds
Step 14 Run one of the following commands to enable Recognized Operating Agency (ROA).
z
x25 call-facility roa-list name
z
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
x.121-address roa-list name
Step 15 Run one of the following commands to enable the sending of broadcast datagrams to the VC
associated with the specified address.
z
Run the x25 map { compressedtcp protocol-address | ip protocol-address } *
x121-address x.121-address broadcast command to send broadcasting datagrams to the
peer of the SVC associated with this address mapping.
z
Run the x25 pvc pvc-number { compressedtcp protocol-address | ip protocol-address }*
x121-address x.121-address broadcast command to send broadcasting datagrams to the
peer of this PVC.
Step 16 Run:
x25 queue-length queue-size
The command configures the length of X.25 VC queue.
Step 17 Run:
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
X.121-address no-callout
Calls cannot be initiated by this address mapping.
Step 18 Run:
x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address
X.121-address no-callin
Calls initiated from this address mapping cannot be received.
By default, the value of SVC maximum idle time is 0 minute. One address mapping is
associated with only one VC. The number of pre-acknowledged packets is 0.

The X.25 of the SR8000 allows the addition of some additional characteristics, including a
series of optional user facilities stipulated in ITU-T Recommendation X.25 to improve
performance or broaden the application.
This section shows how to configure additional characteristics, including the options in the
x25 map ...... and the x25 pvc....... commands. Select and configure these additional
characteristics according to actual needs, X.25 network structure, and the available services
provided by service providers.
