Hi David,
If you are talking about Multilink PPP connections, then the following
applies:
The Multilink Point-to-Point Protocol (MLP) feature provides
load-balancing functionality over multiple WAN links, while providing
packet fragmentation and proper sequencing, and load calculation on both
inbound and outbound traffic.
Multilink PPP allows packets to be fragmented and for the fragments to
be sent at the same time over multiple point-to-point links to the same
remote address. The multiple links come up in response to a dialer load
threshold that you define. The load can be calculated on inbound
traffic, outbound traffic, or either, as needed for the traffic between
the specific sites.
So I believe that when a second B channel comes up then the utilization
should be 40% for the Multilink bundle of those two channels.
But in the case you are NOT using Multilink PPP then I believe that the
utilization for the channels is different. I mean that the first channel
continues to have a utilization of 80% and since the dialer load
threshold is configured at, let's say 80%, then the second channel is
triggered and carries the excess traffic.
