Bandwidth on Demand
The Bandwidth on Demand (BOD) feature allows you to bundle
both B channels in one connection. The second channel is added
and subtracted dynamically according to traffic demand. The
Prestige uses the Bandwidth Allocation Control Protocol (BACP)
and the Multilink Protocol (MP) to implement bandwidth on
demand.
The configuration of bandwidth on demand focuses on the Base
Transmission Rate (BTR) and the Maximum Transmission Rate
(MTR). The relationship between BTR and MTR are shown below:
BTR & MTR Setting No. of
channel(s) used
Max No. of
channel(s) used
Bandwidth
on demand
BTR = 64, MTR = 64 1 1 Off
BTR = 64, MTR = 128 1 2 On
BTR = 128, MTR = 128 2 2 Off
When bandwidth on demand is enabled, a second channel will be
brought up if traffic on the initial channel is higher than the high
Target Utility number for longer than the specified Add Persist
value. Similarly, the second channel will be dropped if the traffic
level falls below the low Target Utility number for longer than the
Subtract Persist value.
The Target Utility specifies the line utilization range at which you
want the Prestige to add or subtract bandwidth. The range is 30 to
