Once upon a time Donald Reiher shaped the electrons to say...
>Has anyone gotten ISDN to work on Channelized T1 into a PM3 with ComOS
>3.5.1b7?

b7??? Or did you mean b17?

You must have meant b17, b7 didn't do channelized.

I'd go to 3.5.1b20 myself actually.

>If so, how do you set it up?

It just works. If you can receive modem calls into the PM-3, you can
receive 56K ISDN DOSBS calls - well, you really want the T1 to be trunkside.
I guess I shouldn't speak in such absolutes - as far as the PM-3 is
concerned, that's it. But there can be telco issues.

>I can dial up with a Zyxel TA128U into the PM3. It connects, and then
>gives a "Cannot establish the Network protocol" error. The same modem
>connects perfectly to BellAtlanticnet.

If it is connecting then you've completed a successful dial. I'd run a
PPP debug onthe PM-3 end to see what is happening in negotiation.
