Me, too. He was talking about two separate boxes. One that plugs into the DSP
port, "but that is not for ISDN", and another that plugs into both RS432 ports.
This was allegedly because ISDN base access offers two separate channels,
so you have one port per channel. I told the guy I considered this a
horrible solution since it will block almost all of my communications IFs.
He said it wasn't a problem since it was enough to have one NeXT on the net
hooked up to ISDN/POTS. This could then be used by every NeXT on the network.
(Very helpful especially for standalone NeXTs :-(
So could you anyone who has the Hayes ISDN Extender for NeXT running and hooked
up to ISDN and/or POTS comment on the following:
How many and which plugs does it have on the NeXT side?
How many and which plugs does it have on the line (wall) side?
Can ISDN and POTS be concurrently accessed?
How high is the system load when transferring stuff over ISDN/POTS
How fast is the POTS modem stuff?
Is Modem / Fax / Answering possible with ISDN/POTS?
Is the DSP available when the ISDN Extender is hooked up
/ running / transferring data
Why did the guy from NeXT talk such strange stuff, or,
Why did I get him so terribly wrong?
Thanks in advance and sorry for the confusion.
