Hi all.
I'm running "barrier breaker" (r42625) on a BTHOMEHUBV2B and it's
great apart from frequent adsl disconnections (approx 40 per day). My
adsl-type is POTS so the relevant part of /etc/config/network is:
config adsl 'dsl'
option annex 'a2p'
option firmware '/lib/firmware/adsl.bin'
Each disconnection puts approximately the following into the syslog:
Fri Nov 14 09:33:41 2014 daemon.info pppd[1218]: No response to 5 echo-requests
Fri Nov 14 09:33:41 2014 daemon.notice pppd[1218]: Serial link appears

My line stats are:
# /etc/init.d/dsl_control status
Chipset: Ifx-Danube 1.3
Line State: UP [0x801: showtime_tc_sync]
Data Rate: 7.040 Mb/s / 924 Kb/s
Line Attenuation: 37.4dB / 21.2dB
Noise Margin: 7.1dB / 10.0dB
Line Uptime: 25m 39s
The disconnections happen more frequently at night time. I have
several of these boxes, and they all exhibit the same behaviour so I
do not believe that it is a hardware problem specific to 1 router. I
also have the original "sky"-supplied router which does not suffer
from these disconnections.
The dsl connection appears to be a bit of a "black-box" - I can find
very little documentation discussing it, although 1 or 2 people have
mentioned XTU bits, which I don't understand.
Is there anything that I can modify to try to stop these
disconnections from happening? Would lowering the connection speed
help, and if so, can this be done?
All info/suggestions would be gratefully received. With kind regards,
Jaime
