Each ISDN terminal device connected to your ISDN basic rate outlet must be assigned a
unique Terminal Endpoint Identifier (TEI). In most cases, this is negotiated automatically. In
some cases however, it may be necessary to assign a fixed TEI.
When TEI is set to 255, the TEI is negotiated with the ISDN network. To use a fixed TEI set
the TEI parameter to the appropriate value as specified by your service provider.
D-channel X.25 Tx Window Size
This specifies the transmit window size when using D-channel X.25. The default is 7.
Tx Throughput
The Tx Throughput parameter is 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 unit 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 unit will limit the rate at which data is transmitted
over the LAPD link.
Note:
Note that if multiple PAD or IP instances are sharing this LAPD instance, the maximum
transmission rates of all instances will be limited.
Rx Throughput
The Rx Throughput parameter is 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 unit 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 unit 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:
Note that 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 this parameter is enabled, the unit will try 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 unit will not attempt to reactivate a D-channel link
following deactivation by the network.
Reactivate after n secs
This parameter specifies 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
This parameter determines if to deactivate or not the LAPD session when an X.25 PAD
session is terminated
Deactivate the LAPD session
This parameter enables automatic deactivation of a LAPD session when an X.25 PAD
session is terminated.
