[nsp] ISDN PRI line drops

We are configuring multilink PPP on ISDN E1 PRI between 2 routers. The
configuration is quite standard and works fine. However after bringing
up a few channels, at around 120 secs, all the channels would drop like
a ton of bricks. Dialer idle timeout is set at 300secs and the lines
will still drop even if there is traffic. This is seen below - just at
120secs and after when all the calls are dropped. Any ideas on why this
is happening?

Many thanks in advance.
