Engineer scheduled for Wednesday. Lets hope he or she is kitted out to look carefully for HR faults.
Engineer called at the house yesterday for a 3rd visit. Using the same JDSU unit as the other 2 Engineers used he detected a further 3 termination issues between our house and the main cabinet. Must have used the TDR as he mentioned a fault 150m away. Once the terminations were re-crimped all audible line noise dissapeared. Engineer was also good enough to re-set the noise margin back to 6 dB hence putting my sync speed back to around 10 Mb per sec. Looking at the stats below it is interesting that Latency type is now 'fast' as it was previously 'interleaved'.
It looks like it was an HR problem afterall. Since this has given me another denial of service for around 2 weeks following a similar outage 6 weeks ago they have refunded half a months line rental (£7). A nice gesture but not a great recompense for the amount of grief this has caused and due to no fault of my own.
Apparently these faults happen frequently in my area and largely down to the distribution network being old and consisting of aluminium cabling laid in the 1970's. I don't think that BT Infinity will help these issues because it only delivers fiber to the cabinet i.e. exchange-side and the IP traffic gets routed through the same legacy distribution network.
I'm glad my connection is stable again but given what has previously happened I'll wait for a couple of months of stability before assuming this is properly fixed. Atleast I know the fault is not down to something in my property. Given the amount of downtime suffered and the time spent following-up and getting time off work to allow Engineers to visit I am not feeling this is a great service but since I have nothing to compare it with I'll stay with BT for a bit longer. I know that Sky et al deliver theiir IP service over BT's network anyway, leaving Virgin as the only viable alternative that uses optical end-to-end.
Thanks to everyone who responded to my updates - I think there's a lot of value in this forum and would recommend that all BT engineers tune-in just to obtain a customer's perspective.
