# Example of an ISDN interface that runs in NT-mode, but provides tones during
# setup. Also we provide tones during setup also.
# This is usefull to interconnect to another PBX.

# Example of an interface on port 0 connected to another LCR
# This can be done by direct cross cable (terminated of course) or via L1oIP.
# Since the remote side (NT-mode) normally doesn't accept informations like
# redirected number or display facility, use 'te-special' to even transmit that
# against the ISDN specifications. A remote LCR can handle that.
# Now all information elements can be transmitted in both directions.
