Re: (ASCEND) PRI does not fill up after reboot

["Ashley" <ascendlist@asnet.com.au>]

The story that we received from Ascend in Australia was that the E1 load of
code was not sending disconnect/connect information to the switch on warm
boots.  If you did a cold boot, the channels would come back.  This was
found in version 6.1.7, & supposedly fixed in 6.1.24 (wasn't in the end).
No issues (like this) have been seen by us in any version 7 load.
