handle_device is the basic script intended to be called from udev. It will call span_types on the span to apply optional /etc/dahdi/spantype.conf onfiguration settings that need to be applied before assignment (currently "pri" port types: E1/T1/J1). Next it assigns span numbers to spans: if configured in /etc/dahdi/pinned-spans.conf - use those settings. If not: by the order of loading. span_types and span_assignments can also be used to report the settings they are used to configure.

# /usr/share/dahdi/span_types:
|
|
#
|
|
# this script can be used both from udev and
|
|
# from the command line for spantype management.
|
|
#
|
|
# It use a configuration file /etc/dahdi/spantype.conf
|
|
# (the format is documented inside this file)
|
|
#
|
|
# The first argument is an action:
|
|
# "list" to show existing E1/T1/J1 types
|
|
# "dump" the same, but in a format (almost) suitable for
|
|
# the configuration file
|
|
# FIXME: we currently don't have the base channo in sysfs.
|
|
# "set" actually write the setting to the driver
|
|
#
|
|
# Examples:
|
|
# span_types list
|
|
# span_types dump
|
|
# span_types set # all
|
|
# span_types set /sys/bus/dahdi_devices/devices/astribanks:xbus-00
