Hello, forum. If I had more time, the question would be shorter.
I am attached to the MRPOY Exchange using the O2/Be LLU, as an O2 customer. ADSL2plus, G992.3. For a description of O2 Customer Service, see dilbert.com, Jan 22nd 2012. Phone Rental is BT Line Saver. If you think BT is bad, try O2 Telefonica for a landline.
I may or may not have connection difficulties, dependent on your viewpoint.
BT test systems say there is no line fault, even when the voice line crackles on the Quiet Line Test.
O2 tier one, two, and three support just shout at me.
The problem is that I lose sync in bursts, and cannot regain sync w/o a cold restart of any bridged connecting device, a DG834 or TG585v7, say. This is an increasingly frequent event.
The only way to solve the problem has been to bridge a 2700HGV, firmware 6.1.1.48-enh, and use that. With a target SNR of 9db, I have a usable connection.
I have a separate router, running TomatoUSB.
The loss of sync seems primarily related to RF interference, The line is also poor. 1.2 km approx from exchange, line attenuation 28db. Sync around 12500 kbits/s at target SNR of 9db. The NTE5A is 3 metres off the ground near the garage ceiling, above the electricity Consumer Unit. I have 2 metres of vertical CW 1308, possibly acting as an aerial.
Street light flickers - was attended to by Council.
Neighbour has Christmas tree lights on 5m fir tree at boundary. Turned off, hopefully for good, on 26th February.
Builder 50m away starts cutting blocks whilst I am watching RouterStats trace. 10 losses of sync in 30 minutes.
Running RouterStats on Mac OS X is challenging.
I have changed faceplate from Austin Taylor -who I think have ceased trading - to a Pressac VDSL Faceplate, which has in built RF3 style chokes. This has caused an improvement, so I am left with 1 or 2 resyncs per day.
The question
Asbokid has shed his identity, so I doubt his work will continue. Does anyone know if there are differences in the handling of loss of sync events by different 2Wire models?
2700HGV, with differing firmware versions, and the 2701?
I have an annoying event between 0600 and 0700. Loss of sync occurs, which may be due to a motor vehicle, even at a target SNR of 9db. The 2wire retrains, and moves the SNR to 14db, where it stays.
I would seek to avoid this.
Suggestions would be appreciated.
