system.sysDescr.0="Ascend Max-HP T1/PRI S/N: 645--88 Software +5.0Ap16+"
system.sysUpTime.0="Timeticks: (111470500) 12 days, 21:38:25"

Running tk.40 image...

This is a MAX4000 with 6 cards x 8 56K series modems with one 
incoming T1 connection.

98% of our 28.8 and 33.6K callers are not having any problems logging in.

The system has been running steadily for the last 12 days since our upgrade.
(I have this weird feeling that I might be jinxing myself).

We did have a Zoom 14.4 user let us know that they cannot connect - but
they are a V.FAST victim.

Another user with a Hayes Accura 56K internal speakerphone voice/fax/data
modem was able to connect okay throughout the weekend and then they
couldn't connect after that.

After they brought the computer to our office and we used our analog FAX
line to test the connection - we also could not connect.

We have two sets of equipment.  This 56K Accura modem would also refuse
to connect to our standard 33.6K analog modems.

After troubleshooting their Win95 Dial-Up Networking system I finally gave
up and called Hayes Tech Support.

They gave me the following initialization string for the user:

AT&F&C1&D2+MS=56,0,34000,42000

This restricts the connect negotiation window from 34000 to 42000.

What happens is that the modem with the factory defaults first tries to
negotiate 56,000 then 55,000 then 54000, then 53,000, etc..

Usually we get a time out at this point.  By restricting the window the
user is able to connect first shot, everytime!

Eventhough I anxiously await new modem code for our cards, I am quite happy
with the result.  Some of the horror stories in this mailing list are
terrible.

I just figured I would contribute this little experience.  Our upgrade also
went as smooth as silk.  After finding out about the needed hash codes, etc,
our upgrade took about 15 minutes and never once did we need to call
Ascend Tech Support other than to get the hash codes faxed over (3 days
before we attempted the upgrade).

Has anyone else had any pleasant experiences with the upgrade to the new
56K series cards - or are we the only ones ? :(
