Re: (ASCEND) Pipe 75 analog voice features

I posted a reply to comp.dcom.isdn on this....I didn't realize it was
cross posted here. Anyway:

This is a little misleading. The P75 interprets the appropriate switch hook
transitions and converts them into ISDN messages for the ISDN switch
to understand.

That is the intention. We are trying to make it "transparent" to the POTS port.

Button assignments are what the Pipeline uses to communicate with the
ISDN switch when you make the POTS port switch hook transitions. The
switch hook transitions are NOT sent to the switch, as they are analog
signals. The switch receives feature messages that refer to the appropriate
button numbers.....that's where they come into it.

NOTE that I believe this is switch dependent, see:

They are described completely in the 6.0 release notes. Some of the features
require single switch-hook transitions, others require double switch-hook
transitions. These features can be disabled if desired.
