That does sound like a problem. Are you using NFAS on your 4004?
With NFAS, since two or more PRI lines use the same D channel, an error
on the D channel can cause a failure of a large number of B channels.
You can find the Ascend Disconnect/Progress Codes and ISDN Cause Codes
on the Ascend web site.
http://www.ascend.com/898.html and http://www.ascend.com/896.html
45 PPP - Receive Terminate Req
185 Remote End Hung Up
Cause No. 16 - Normal Call Clearing
This cause indicates that the call is being cleared because one of the users
involved in the call has requested that the call be cleared.
Cause No. 102 - Recovery On Timer Expiry
This cause indicates that a procedure has been initiated by the expiry of
a timer in association with Q.931 error handling procedures.
The only one of the codes that look unusual is the ISDN cause code of 102.
