Menus Reference Manual: Edit Remote Site - Protocol Menu
6 - BACP Set-Up
The BACP Parameters menu allows you to activate the BACP (Bandwidth Allocation Control Protocol) and set the call
conditions used. BACP reduces network charges by adding or dropping the second link based on traffic demands. BACP
mediates control of the link between the routers to prevent "link bobbing".
Note: this option will only be displayed if this remote site connection is configured as ISDN or PPP Leased and the dual-
link option is enabled.
7 - Multilink Operation
This option determines whether the connection to this remote site will operate using single link protocol or PPP
multilink protocol. Multilink protocol allows multiple links to be connected between two routers. The physical links
may be of different types (e.g. Leased and ISDN)
Default:
[disabled]
ISDN Considerations:
When multilink operation is changed for a group, all active ISDN calls will be disconnected.
When the router receives an incoming call, the Multilink state is taken from the "ISDN_TEMPLATE" remote site
profile. Note that if Multilink is disabled in the "ISDN_TEMPLATE" and an incoming call requests Multilink, the
router will negotiate to have Multilink enabled.
When a PPP router with Multilink disabled attempts to establish an ISDN connection to an Ascend router with
Multilink enabled, the Ascend router will shut down the ISDN call. Simply set the Multilink values on each of the
routers to be the same value and then establish the ISDN connection.
Note: if the primary connection for this remote site is frame relay, PPP encapsulation must be enabled for this option to
be displayed.
