In case it is of some interest I thought I would post on progress with a new FTTC connection and related testing. The connection is the first on the cabinet so I expect it to start good and then suffer increasing cross-talk.
The install (I have mentioned most of this in a related post but put it here as the starting point.)
An Openreach engineer came last Friday pm and seemed very capable. He installed the filter and ECI modem, did work at the cabinet called the exchange a few times, and tested the sync etc but was not interested in the strange actual download speeds resulting. In spite of a 80/20 sync throughput varied between 1 and 74mb/s
this continued over the weekend and 1mb/s occurred quite often.
On the following Monday an email re another engineer visit came. I phoned TalkTalk Business and I discovered that Openreach denied that I had had an install and denied that I am or can be connected to FTTC. After a couple more calls to TTB technical support they finally agreed that Openreach must be wrong and TTB think the engineer may have omitted to sign the job off! Just before the engineer finished at 16:30 the poor engineer had a phone call sending him some 50 miles and was not pleased - I guess this relates to his possible omission. The lack of that sign off seems to mean that TTB can't control my connection, they can detect it but most info is just missing apart from the PPOE login and identifying the connection as FTTC. Late on Monday the connection suddenly started to work as it should with a 72 -75 mb/s download each time tested
- I guess something was done somewhere.
However the saga continued through the week with Openreach finally admitting that I am connected on the Wednesday when an install was done next door. Openreach now on the Thursday say they will "complete" the order today! I will update as this happens or does not............ I am told it has completed a week later to the hour however technical support are still unable to control setting related to my account - I suspect a continuing saga!!
Interestingly I am told that the DLM initialization does not start till it is signed off. You never know what is really true when your told these things but it suggests that in principle it could be turned off.
I hope nothing else goes wrong!!
