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.

           Reading from this file shows if if the if the specific XPD is registered. Writing to
