[*] QoS on Shaw

[John Lange]

Bill, what exactly is a DOCSIS modem?

The modem I have here which was given to me when we upgraded to Shaw
Extreme is a "Motorola SB5100 SURFBoard Cable Modem". Is this the
DOCSIS?

That doesn't seem to jive with what I know about the Shaw phone service
as it doesn't have anything on it that looks related to phones.

One administrative note; can we change the list so replies go to the
list? I Don't know how others feel about that but I find it more
convenient.
