2851 w NM-1CET1-PRI & PVDM2-12DM - Modem lines being marked "B" Bad
We recently setup a new 2851 router (IOS 12.4(11)T1) for remote dialup access. It has a ISDN PRI network module NM-1CE1T1-PRI and a 12 port Digital Modem Module (PVDM2-12DM) installed to receive the inbound modem calls.
When the router is booted up, inbound remote dialup connections work fine for several hours. Then the router digital modem lines begin to stop working. For example, an inbound call is made but the modem tone does not answer. However a "show modem call-stats" shows that a line becomes active with a "*" symbol. When the call is hung up, the line remains in an active "*" state. Eventually the state changes to a "B - Modem is marked bad and cannot be used for taking calls". This symptom will repeat itself with each new inbound call until all of the lines are marked "B". Only a router reboot will temporarily correct the problem.
Additional symptom, "show modem version" changes to "NiOS Not Responding".

I'm having the same problem with a 2811, NM-2CE1T1-PRI, and 2 PVDM2-24DMs. CSM last event: WDT_TIMEOUT and the modems will not clear unless a full reboot is done. Was there a solution to this issue? Thank you!
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
