I'm running ISDN4BSD 1.6.1 on FreeBSD 7 (-current) with a HFC-based PCI
card:
ihfc0: <HFC-2BDS0 128K PCI ISDN adapter> port 0xd000-0xd007
mem 0xee024000-0xee0240ff irq 12 at device 6.0 on pci2
ihfc0: Attaching I4B controller 0.
ihfc0: Creating /dev/ihfc0.X.
The card is connected to one of the two phone ports of a Swiss
Telecom NT-BA 1, using a crossover cable (3-4, 4-3, 5-6, 6-7) without
resistors (I'm assuming the NT-BA provides power and termination,
correct?).
On the second port of the NT-BA I connected a standard Swiss ISDN phone,
using a straight cable. The phone gets power through the NT-BA fine. The
phone has MSN "1" configured.
Then I set up NT-mode using
# isdnconfig -u 0 -p DRVR_DSS1_P2P_NT -n -a
# isdnconfig
controller 0 = {
Layer 1:
description : HFC-2BDS0 128K PCI ISDN adapter
type : passive ISDN (Basic Rate, 2xB)
channels : 0x3
serial : 0xabcd
power_save : on
dialtone : enabled
attached : yes
PH-state : G3: Active
Layer 2:
driver_type : DRVR_DSS1_P2P_NT
}
When running isdntrace, I see L1 state changes (when I run isdnconfig
-D/-a), but nothing else:
# isdntrace -u 0 -b -i
=========== isdntrace controller #0 =========== started Wed Nov 8 13:42:13 2006

I tried to use isndphone to dial "1", but nothing happened (stuck in
"state: DIALING", no trace output, ISDN phone shows no activity).
When I use the ISDN phone to dial any number, nothing happens, either, and
the phone shows "No connection", no trace output.
Is my assumption wrong that I should be able to dial the ISDN phone from
the FreeBSD box and vice-versa in this setup?
If that should work, does the above output indicate a problem with the
cabling? Unplugging the crossover cable doesn't even produce an isdntrace
output, should it?
Or did I configure the controller wrongly? I'm not sure whether I need
DRVR_DSS1_P2P_NT or something else, or whether isdndebug -T and/or -p must
be used specifically.
Can any of the existing isdn*(8) tools be used to test this setup?
