Rate Adaption parameters
The router supports two rate adaptation protocol (Adapt) instances. Each instance enables the
selection and configuration of the protocol to use 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 error-corrected (multi-frame) mode uses V.120 . Clicking the triangle at the left of
the Rate Adaption bar opens up the two instances described below.
This page displays the configuration parameters directly relevant to the rate adaptation protocol
only, LAPB configuration pages are to be found here in the Configuration > Network > Legacy
Protocols > X.25 > LAPB page. When configuring LAPB parameters, be aware that adapt 0 uses
LAPB 2 and adapt 1 uses LAPB 3 .
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 time to wait before dropping the connection if the connection becomes idle.
Leased line mode
When enabled, allows the router to attempt to maintain the connection automatically once it
has been established.
Enable TCP rate adaption
When enabled, enables 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
The port number that the router is listening on when in socket mode.
