Hmmm....who is your telco? For the old Concert network (now BT Ignite) I know they use ANSI LMI with a keep-alive interval of 10 secs. Make sure your settings match your telco's.
What I always advise to do is to use a sniffer to see what's actually going on on the line. This way you can quickly identify if your router is receiving the right LMI type at the interval the telco states.
