With the new CRTC decision allowing Bell and the like to impose metering/usage caps, I was curious if this will have any connection to Sasktel? I know that Sasktel doesn't have any usage caps right now (or if they do they are so ludicrous so as not to be relevant) but I'm always interested what's on the horizon. Anyone know?

I doubt bandwidth caps would make any financial sense to implement. The equipment to monitor and shape connections is quite costly. It might make financial sense if Sasktel was faced with high upgrade costs (due to under-provisioned DSLAMs like Bell) but most of Sasktel's network is over-provisioned already for IPTV services.

Besides, the lack of bandwidth caps is a great competitive differentiator against competitors like Shaw (who does have bandwidth caps in many areas). Does anyone know if Access has bandwidth caps?

Yes, SaskTel owns their own lines

we put them in ourselves

and we put in most of Access's original lines too

SaskTel own's their own lines to a point. Or so I found out last year when I had to do a repair in side my residence. I had to purchase something called wire watch(?) in order for them to come into my house and fix a jack. As far as I know though they are their own network and because of that they don't have to limit the amount of usage on their services. I got rid of access because of this. No shared bandwidth with your next door neighbour and they don't have limits on the amount you can download.

Yes, thats the demarc(ation) that you're referring to. Back in the olden days, all the telephone wire inside your house also belonged to sasktel.
Deregulation occurred and now anyone/everyone can install their own telco wiring.

So because the owner is now responsible for their inside wiring, we charged hourly rates for inside repairs(just like an electrician would)

Wire watch is basically inside wire insurance that you pay monthly, rather than hourly service fees.
2 years of wire watch is less than 1 hour of service call, so it's relatively cheap.
