[cisco-nas] AS5350 Connection Problems

[Internet Coordinator]

We experienced this issue in March when we upgraded all 15 of our
5350s.  We didn't have time to worry about it at the time so we
downgraded back to 12.1-5.xm8 which also downgraded the firmware for the
nextport modems.  Now that we have time re upgraded all boxes to
12.3(1a) and added a modemcap

modemcap entry next:MSC=&FS0=0S29=6S21=3

This has corrected thing BUT we needed to put in an INIT String for GWT
v92, BCM v92 and PCTel v92 modems.  Normally correcting it with +ms=v90
or +ms=v90,0

Not sure if this will clear it up for you but this was what we did to
get updated past the IPv4 bug.

thanks
