asterisk users - Feb 2005 - AST -> Channel Bank Hangup Problem

We are seeing a situation where, under busy call volume, Asterisk 
hangs up an channel going into a channel bank (via T-1 interface), but 
the channel bank does not see the hangup and keeps the channel offhook.

Has anyone seen this problem before?  Did you find a solution.

Asterisk(T-1 port) -> Channel Bank(analog FXS port) -> PBX(analog FXO 
port)

What channel bank?  I have a Adtran TA750 and the BCU had outdated firmware.
Upgrading the firmware fixed this problem in my case.
