Good morning all,
I have a USRobotics Total Control NETServer/16
I-modem which I hope to use for dial-in access for remote
users.
I have had 4 ISDN lines installed. These are
connected to a network terminator and then the NETServer. The switch protocol used here in Northern Cyprus is Euro-ISDN
(I have confirmed this many times with the not-so-helpful telcom
staff)
The problem I have now is as so:
1. When I set the switch protocol to Euro-ISDN
(*w=2 or ETSI-NET3) the Physical Interface goes Active but the Data Link Layer
is inactive. After about a minute both the Physical Interface and Data Link
Layer goes inactive.
2. While playing around with the settings, I set
the switch protocol to AT&T (*w=0). When I do this both the Physical
Interface and Data Link Layer go Active. However I cannot dial out (atdt command
gives NO RESPONSE or NO CARRIER) and no one can dial in.
A technician told me that Euro-ISDN is indeed the
protocol to be used and that the telecom have obviously not setup the line
correctly (something about the Data Link being activated). The telecom people
however keep telling me that they have done everything on their end and that
there is a problem with the settings on my modem or that my modems are not
working. All 16 of them!
Every person I talk to seems to say something
different. I was wondering if anyone could shed any light on to this problem.
Has anyone had a similar experience before?
Many thanks once again.
