Not 100% sure what's just happened. So thought that I'd seek some expert opinion.
Been with Newnet for a couple of years now (ADSL MAX up to 8Mbps).
Up till about a day ago I always syc'd at 8,096Kbps with a 7000K profile according to BT speed tester. Attn has always been 33/34dB and SNM varies between 6 and 9 dB (evening/daytime). Line usually stays up around 20/30 days until FECs appear to build up high enough and then it re-sets.
Well. Router just stayed up for what must be a record now (46 days I think) and just noticed that it has re-syn'd. But.... stats now say:
Uptime: 0 days, 19:59:03
Modulation: G.992.1 Annex A
Bandwidth (Up/Down) [kbps/kbps]: 448 / 8,128
Data Transferred (Sent/Received) [MB/MB]: 15.91 / 95.75
Output Power (Up/Down) [dBm]: 12.0 / 19.5
Line Attenuation (Up/Down) [dB]: 17.5 / 33.0
SN Margin (Up/Down) [dB]: 22.0 / 6.0
Vendor ID (Local/Remote): TMMB / µ
Loss of Framing (Local/Remote): 12 / 0
Loss of Signal (Local/Remote): 3 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 4,377 / 0
FEC Errors (Up/Down): 0 / 0
CRC Errors (Up/Down): 0 / 4,965
HEC Errors (Up/Down): 0 / 1,808
So good news is that my sync speed appears to now be the max obtainable on ADSL max. But.... I see that the FEC count is zero! Never seen this before! Does this now mean that the exchange thinks my line is good enough to remove interleaving?
Have not yet been able to run BT speed tester (what's new I suppose in the evening). But all other testers (including this sites) seems to be indicating a 2Mbps download speed! Though obviously maybe not representative in the evening. Though always before (even in the evening) it's been 4Mbps or above. So just wondering what's going on???
Obviously need to try and run BT speed tester tomorrow morning (just wondering what my IP profile is now!), maybe more luck then.
Any thoughts anyone?
I'm amazed if this line can support anwhere near the max speed with interleaving off!!
(if this "is" the case).
PS. Best part of 3km as the crow flies from the exchange and some 3.5 km by road (which I know is where the cable runs).
PPS. Can't help but notice that my error seconds, CRC and HEC errors are climbing quite fast now (did not used to). Why O why can't BT leave things alone!!!
