Configuration – Network > Interfaces > Serial > Rate Adaption
The router supports two rate adaptation protocol (Adapt) instances. Each instance enables
the selection and configuration of the protocol to be used for rate adaptation over an ISDN
B channel. The supported protocols are; V.110, V.120 and X.75. Depending on which
protocol is selected, there may be an associated LAPB instance (distinct from the two
general purpose LAPB instances), as for example, when V.120 is used in error-corrected
(multi-frame) mode. Clicking the triangle at the left of the blue bar opens up the two
instances described below.
Configuration – Network > Interfaces > Serial > Rate Adaption n
This page displays the configuration parameters directly relevant to the rate adaptation
protocol only, LAPB configuration pages are to be found here: Configuration – Network >
Legacy Protocols > X.25 > LAPB. When configuring LAPB parameters, be aware that
LAPB 2 is used for adapt 0 and LAPB 3 is used for adapt 1.
Attempt to redial the connection n times if rate adaption has not been negotiated
If an ISDN connection is established, but rate adaption is not negotiated, the value in this
text box specifies how many times the router should drop the connection and redial it.
Drop the connection if it is idle for h hrs m mins s secs
The values in these text entry boxes specify the time to wait before dropping the connection
if the connection becomes idle.
Leased line mode
When checked, this checkbox will allow the router to attempt to maintain the connection
automatically once it has been established.
Enable TCP rate adaption
Check this checkbox to enable the use of rate adaptation when using a TCP connection
rather than an ISDN line. When enabled, the following controls become enabled:
Connect to IP Address a.b.c.d Port n
When using a TCP connection, these text entry boxes allow the user to specify the IP
address and port number that the protocol should use.
Listen on Port
This text entry box contains the port number that the router is listening on when in socket
mode.
