So although you manually reset the modem. The remote ISDN switch
initiated the disconnect at the ISDN level.
What probably happened is the modems negotiated disconnect. The remote
modem hung up first. This caused an ISDN level Circuit disconnect
request originating from the remote end.
(remote is other end,local is PM3)
So the PM3 is reporting correctly. It would be nicer if the report was a
bit more useful.
E.G. Local LAPM modem disconnect, Call Circuit closed remotely.
Or. Local Administrator reset.
But this will not be a high priority as far as Lucent are concerned,
unless a lot of their customers make it so.
Lucent priorities are Reliability, Stability, Urgent/Significant
Features, Nice features.
This will be in the nice features catagory.
