(PM) Signal "busy" but enough lines!?

Hi,

I've a strange problem...

I've a cascade of 7 PRA with 4 PM3 interconnected with OSPF. Each PM3 is full
of modem cards (so it can answer the max. number of lines: 60)

The problem is that some modem users receive a busy signal when dialing
the cascade but I'm 100% sure that we still have free channels
(I asked my telco op. to check and we never go over 80% of used lines)

What can be the problem? Some defect modem cards? Telco bottleneck? ...

Help!

Xavier
