said by patcat88:Teksavvy does not buy dedicated pipes from BC. AFAIK no CLECs in Canada do. In the USA CLEC DSL is different, the CLEC must install their own DSLAM at the CO, and then the CLEC must get the traffic from their own DSLAM to the internet and out of the CO building.
In Canada, CLECs buy a packet switched (idle bandwidth uses no room) ethernet link from BC, and the ethernet link is filled with incoming VPNs. Each VPN is the traffic of that CLEC's customer's modem. The bandwidth each VPN uses can expand or decreased based on how much bandwidth the CLEC customer is using. Its not an SONET/ATM/T1/T3/ISDN link where if you have 10 customers each with a 3 mbit DSL link, you will get a 30mbit T3 from BC, and idle frames take as much room as a full frame. BC suffers the effects of contention on this business model. CLEC DSL in Canada is not circuit switched, its packet switch. Teksavvy will NEVER buy a "[# of customer]*[their DSL plan's speed]" ethernet link to BC. Also because of having to deliver all the CLEC DSL customer's traffic to a single point, over inter-CO links, BC suffers congestion.
In the united states, this case would be much different, and laughable. Teksavvy puts a DSLAM in the CO, and place connection order to ILEC. ILEC installs a DSL modem in the CO, and connects Teksavvy's customer's pair to the ILEC's DSLAM, then connects an ethernet port from the ILEC's DSLAM to the ILEC's DSL modem, then take the POTS pair from the ILEC's DSL modem and gives it to Teksavvy to plug into their DSLAM, and throttles between the ILEC DSL modem in the CO, and the ILEC DSLAM in the CO. For a final mess, look at the below.
[Teksavvy DSLAM in CO]--POTS--[ILEC DSL modem in same CO]--eth--[throttling server in same CO]--eth--[ILEC DSLAM in same CO]--POTS--[Teksavvy's customer's DSL modem at house]
lol
If it really was 3rd party DSL, you could get VDSL2, IDSL, ADSL2+, RADSL, UDSL, SDSL and SHDSL from Teksavvy for relatively the same price.
I'll not say I completely disagree cause some of the critique above maybe true.... nonetheless teksavvy is buying some form of 1 Gigabit links through which to route the traffic to their servers (meaning that at the moment TSI cannot push more than 5Gbit/s to their servers through Bell's network...I'll stop there because my understanding is limited beyond this point). Granted those links aggregated may not be able to support every single customer being online simultaneously however usage at any specific time usually does not surpass 50-60% of capacity
