Configure the BACP options you want implemented on your DIVA T/A. Use the table below as a guideline.

Parameter	Description
BACP/BOD	Note: Only applicable if your ISDN connection
(Bandwidth	protocol is Multilink PPP.
Allocation	Activates the DIVA T/A's automatic traffic
Control	monitor for Multilink PPP connections. When
Protocol/	activated, this DIVA T/A function monitors the
Bandwidth on	send-and-receive traffic volume.
Demand)	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 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

Timers

Note: Only applicable if your ISDN connection protocol is Multilink PPP.

Note: You must activate BACP/BOD before setting the timers.

Set these timers if your ISDN Service Provider charges one rate for the first interval of time on- line (a fixed period, for example the first 5 minutes), and a different rate for subsequent time on-line. Setting these timers ensures your second B-channel is used most economically.
