Configure rate adaptation
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.
ÉWeb
1. Go to Configuration > Network >Interfaces > Serial >Rate Adaption.
There are two rate adaption instances. These pages show 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.
2. Configure rate adaption parameters as needed:
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:
