dahdi_registration

DAHDI_REGISTRATION(8)					User Contributed Perl Documentation				     DAHDI_REGISTRATION(8)

NAME

       dahdi_registration - Handle registration of Xorcom XPD modules in dahdi.

SYNOPSIS

       dahdi_registration [-s sortorder] [on|off]

DESCRIPTION

       Without parameters, show all connected XPDs sorted by physical connector order.	Each one is show to be unregistered (off), or registered
       to a specific dahdi span (the span number is shown).

       All registerations/deregisterations are sorted by physical connector string.

       Span registration should generally always succeed. Span unregistration may fail if channels from the span are in use by e.g. asterisk. In
       such a case you'll also see those channels as '(In use)' in the output of lsdahdi(8).

   Parameters
       off -- deregisters all XPD's from dahdi.

       on -- registers all XPD's to dahdi.

   Options
       -s sort_order
	   The sort order to use.

       If the option is not used, the sort order is taken from the environment variable XBUS_SORT and failing that: the hard-coded default of
       SORT_XPPORDER.

       The available sorting orders are documented in Dahdi::Xpp manual.

   Sample Output
       An example of the output of dahdi_registration for some registered Astribanks:

	 $ dahdi_registration -s type
	 XBUS-01	 usb:0000153	 usb-0000:00:10.4-2
		 XBUS-01/XPD-00: on Span 1
		 XBUS-01/XPD-01: on Span 2
	 XBUS-00	 usb:0000157	 usb-0000:00:10.4-4
		 XBUS-00/XPD-00: on Span 3
		 XBUS-00/XPD-01: on Span 4
		 XBUS-00/XPD-02: on Span 5
		 XBUS-00/XPD-03: on Span 6

	   Reading from this file shows if if the if the specific XPD is registered. Writing to it 0 or 1 registers / unregisters the device.

	   This should allow you to register / unregister a specific XPD rather than all of them.
