Making or receiving a PHONE call improves SNR??

[santosh.s]

Same observation here, one call (or just a minute of dial tone, for that matter) is enough to get the link back. It continues to work with improved SNR for quite a lot (may be half an hour to several hours depending upon line condition).

See the "CTscan" of the ADSL splitter!

Data signals "don't care" whether anything is connected in Phone port or not !!!

Same problem with mine!
ADSL was working fine till about 3-4 days back when it started to blink continuously
happened to 'discover' this (temporary) solution

Earlier whats used to happen was, picking up the receiver would reset ADSL

Details:
Modem - D-Link GLB-502T (Inbuilt Splitter)
ISP - MTNL
Exchange Distance - (Bang across the road.... :/)

Receiver on Hook details:
US Margin - 6
DS Margin - 9
DS Attenuation - 10
US Attenuation - 9

Receiver OFF Hook details:
US Margin - 16
DS Margin - 30
DS Attenuation - 7
US Attenuation - 2

Net working fine now (past 24 hours) Lets see

id suggest you better complain about the unstable link to the bsnl guys, than resort to these 'solutions'. There may be some loose joints, untidy connectors etc.
