My line has recently been migrated from 20CN to WBC. Downstream attenuation is now 33db and syncs at 14,000 Kbps (which I think is pretty good) with a 6db margin. Line is rock steady and stays up for weeks at a time.
I have a few questions:
1. I'm on fast path. Previously on ADSL1 I was getting perhaps 200 error seconds a day, now on ADSL2+ I am getting 2000 errors a day. They don't seem to be impacting on throughput - does 2000 error seconds a day seem excessive ?
2. When I first sync'd (during the day) I didn't have any gaps
but over time a large number of gaps in the bit loading graph have appeared:
Gap1 1376kHz-1380kHz (Tone319)
Gap2 1423kHz-1427kHz (Tone330)
Gap3 1440kHz-1445kHz (Tone334)
Gap4 1656kHz-1660kHz (Tone384)
Gap5 1669kHz-1678kHz (Tone387-Tone388)
Gap6 1721kHz-1734kHz (Tone399-Tone401)
Gap7 1747kHz-1751kHz (Tone405)
Gap8 1837kHz-1841kHz (Tone426)
Gap9 1846kHz-1850kHz (Tone428)
Gap10 1885kHz-1889kHz (Tone437)
Gap11 2057kHz-2061kHz (Tone477)
Gap12 2074kHz-2079kHz (Tone481)
Gap13 2087kHz-2100kHz (Tone484-Tone486)
Gap14 2117kHz-2126kHz (Tone491-Tone492)
Gap15 2139kHz-2143kHz (Tone496)
Gap16 2148kHz-2161kHz (Tone498-Tone500)
Gap17 2165kHz-2204kHz (Tone502-Tone510)
Is this normal ? This looks like quite a lot of noise to me ? Is there anything I can do about this - my setup is a NTE5 master socket (in the hall) which is extended via 2 meters of CAT 5 cabling to a face plate filter (on a slave NTE5) in my study.
3. My upstream is currently capped at 448Kbps - if I uncap the upstream is that likely to make the errors/gaps any worse ?
Thanks for any help,
