# Example of an ISDN PRI interface on port 0 that has directed channels.

# 10 channels (channel 11-15,17-21) are outgoing only.
# 10 channels (channel 22-31) are both way.
# We prefer to use directed channels first, then we request any channel.

# 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.

# They are: setup, dialing, proceeding, alerting, disconnect

# 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.

# Example of an ISDN interface on port 1, with alternate tones_dir to use.

# A special case for GSM Network interface.
# Don't remove/change the settings, they will cause undefined behaviour

# You may add 'extension' and 'msn' keywords to turn all your subscribers
# in you GSM network to internal 'extensions'.

# Use chan_lcr (Asterisk PBX interface) as internal interface.
# The interface requires mISDN_l1loop.ko to be loaded:
#  modprobe mISDN_l1loop nchannel=8 # use up to 8 b-channels
# The caller ID is used as extension, if "extension" parameter is given.
# Use "screen-in % xxx" to modify any caller id to xxx.
# An internal extension does not receive tones ("earlyb"), but sends them.
