I'm a bit stumped here, wondering if anyone else has seen this or is
using the same kit with no issues. Even better if you happen to be one
of our resellers.
Zyxel SBG3300-N router
21CN lines (ADSL or FTTC with or without OR modem) but not all lines
Juniper MX480 LNS
Symptoms are high packet loss and frequent disconnects but only on some
lines.
Swap the Zyxel for a Cisco, problem goes away.
Take the Zyxel to a different line, problem goes away. (This may be true
with two lines into the same building via the same exchange.)
Different Zyxel (same model) from a working line to the problem line,
problem persists.
Terminate the user on one of our Cisco LNSs but same router and line,
problem goes away.
This problem first appeared at the start of the year, went away for a
while, and has now returned. Most of this customer's lines are in
Scotland. Problem exists with current and previous versions of the Zyxel
firmware.
Does anyone have any ideas? We're trying to get BT to look for
commonalities between affected lines but haven't had an answer yet.
