OWNSPEEDING
In the
Bonding
section of the
Settings
tab, you can configure ISDN channel
bonding parameters that affect downspeeding functionality.
Note
The
Bonding
section is not available in Gateway-Serial.
Downspeeding is the ability to complete and maintain a call when ISDN
conditions are bad. In downspeeding, call capabilities are automatically
renegotiated when a call fails. Downspeeding contributes to a higher percentage
of call completion on the network. The LifeSize Gateway supports
downspeeding at call setup and in mid-call.
With downspeeding, when connection problems occur at call setup, the LifeSize
Gateway attempts to connect a call at a lower bit rate than that requested.
Administrators can configure the LifeSize Gateway to attempt to connect a
video call at a specified minimum bit rate, or to attempt to connect the call as a
voice call.
In downspeeding, when connection problems occur in mid-call, the LifeSize
Gateway attempts to connect a video call at the specified lower bit rate. When
downspeeding is complete and the call is connected at the specified lower bit
rate, the LifeSize Gateway notifies the Internet Protocol (IP) endpoint of the
new call rate.
