Step 15
Run one of the following commands to enable the sending of broadcast datagrams to the VC
associated with the specified address.
•
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.
•
Run the

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.
