Configuring network interfaces
D-channel X.25 Tx Window Size
The transmit window size when using D-channel X.25. The default is 7.
Tx Throughput
Used in conjunction with the Rx Throughput parameter to limit the maximum data
throughput on a LAPD link in bits per second.
If this parameter is set to 0, the router will transmit data across the LADP link as fast as
possible whilst observing hardware or software flow control if enabled.
When set to a value greater than 0, the router will limit the rate at which data is transmitted
over the LAPD link.
Note If multiple PAD or IP instances are sharing this LAPD instance, the maximum transmission
rates of all instances will be limited.
Rx Throughput
Used in conjunction with the Tx Throughput parameter to limit the maximum data throughput
on a LAPD link in bits per second.
If this parameter is set to 0, the router will transmit data across the LADP link as fast as
possible whilst observing hardware or software flow control if enabled.
When set to a value greater than 0, the router will limit the rate at which data can be received
over the LAPD link when it detects that receive throughput exceeds the specified rate.
Note If multiple PAD or IP instances are sharing this LAPD instance, the maximum transmission
rates of all instances will be limited.
Reactivate D-channel connection
When enabled, the router tries to reactivate a D-channel connection after disconnection by the
network by transmitting SABME frames. If it is unable to reactivate the connection after
retrying the number of times specified by the N400 counter, it will wait for 1 minute before
repeating the retry sequence.
Enabling this parameter also deactivates the Reactivate after n secs parameter.
If this parameter is disabled, the router will not attempt to reactivate a D-channel link
following deactivation by the network.
Reactivate after n secs
The number of seconds a deactivation has to be present before the LAPD instance will try to
reactivate itself.
After X.25 PAD session is terminated
Determines whether the LAPD session is deactivated when an X.25 PAD session is terminated.
Deactivate the LAPD session
Enables automatic deactivation of a LAPD session when an X.25 PAD session is terminated.
Do not deactivate the LAPD session
Ensures the router does not deactivate the LAPD session when an X.25 PAD session is
terminated.
