BACP Tab

This tab allows you to configure the BACP options you want implemented on your DIVA T/A.

Note that this tab is visible only if the protocol is set to ‘MultiLinkPPP’.

Use the table below as a guideline for setting these parameters.
Parameter Description
BACP/BOD
(Bandwidth
Allocation
Control
Protocol/
Bandwidth
on Demand)
This option only applies if your ISDN connection protocol is set to ‘Multilink PPP’.
‘BACP/BOD’ activates the DIVAT/A's automatic traffic monitor for Multilink PPP
connections. When activated, this DIVAT/A function monitors the
send-and-receive traffic volume.
Without AO/DI support: ‘BACP’ opens or closes the second B-channel as the
traffic volume warrants. Activate this function to ensure that two B-channels are
never active when one is sufficient.
With AO/DI support: When additional bandwidth is required, ‘BACP’
automatically adds B-channels of 64 Kbps each (for a total of 128 Kbps speed
when both B-channels are in use) to the connection. When the additional
bandwidth is no longer required, one or both B-channels are dropped, leaving
the D-channel connection in place.
Note: Be sure to configure the ‘Cost Reduction Timers’ (see next option) to avoid
numerous first interval charges. If you select ‘BACP’, but do not set the ‘Cost
Reduction Timers’, you could incur unnecessary expense as your second
B-channel might open and close frequently, costing you the first-interval amount
each time the second B-channel connects.
Default: ‘BACP/BOD’ disabled.
