Description
BAP, Active Mode and
BAP, Passive Mode
Submenu Advanced Settings
Meaning
BAP=Bandwidth Allocation Protocol
BAP, Active Mode must be set for L
P = AO/DI (=Always On/Dynamic
ROTOCOL
ISDN). The function AO/DI depends on the type
of device. See data sheet on
ec.com to check whether your gateway sup-
ports it.
The Bandwidth Allocation Protocol (BAP) has
three different modes for negotiating a band-
width change. The two negotiating partners
take opposite roles. In this scenario the remote
connection partner must always be in the oppo-
site role or in BAP, Active and Passive Mode.
The negotiating partners behave as follows:
■
Call Request: The partner in Active Mode
wants to add a second B-channel. He
sends a Call Request. A partner in Passive
Mode accepts the Call Request of the nego-
tiating partner if applicable. The partner in
Active Mode thus opens the B-channel.
■
Callback Request: The partner in Active
Mode requests the partner in Passive Mode
to add a second B-channel. He sends a
Callback Request. A partner in Passive
Mode accepts the Callback Request if ap-
plicable and opens the channel.
■
Link Drop Request: The partner in Active
Mode wants to drop a B-channel. He sends
a Link Drop Request. A partner in Passive
Mode accepts the Link Drop Request of the
negotiating partner if applicable. The part-
ner in Active Mode then drops the channel.
