Anyway the Telecom connection is on my second phone line pair in the house and the connection goes directly to the Telecom modem. There is no master splitter since I don't have a phone on the line).
Ran a few speed tests and this is typical of the results.

These are the modem stats (no idea if they are good or not).

From a subjective point of view local browsing is noticeably slower than my TCL connection but that is a Warpspeed 100Mbs/10Mbs connection. Internationally not so much with speedtests (I know they are not super scientific) about the same.
Watching streaming videos from Netflix, Amazon and Vudu is about the same with the usual buffering etc. so switching to Telecom didn't solve that problem, alas.
Any comments would be useful, thanks.
