[cisco-voip] VoIP over Motorola's Canopy?!?

[Eric Helm]

SM=Subscriber Module=Motorola lingo for CPE.
Keep in mind that the 20 mbps (13-14 actual) throughput is shared among
all the subscribers on the AP. With that said, the Canopy system does
have 2 queues (channels in Moto terms). You can use Diffserv to map your
VoIP traffic into the high priority channel. Setup for this actually
happens on the SM side, and the AP should honor these settings as well.
You shouldn't have any problem running VoIP over Canopy with 7 SMs
attached to your AP.
In our residential network, we have some VoIP running on APs that have
100+ subscribers on them. It runs pretty good overall, but there are
definitely times of degradation on the VoIP. I think it is a PPS
limitation of the Canopy in our case.
