NAME

       dahdi_scan — Print Configuration of DAHDI Spans

SYNOPSIS

       dahdi_scan [spans]

DESCRIPTION

       dahdi_scan  prints  information  about DAHDI spans in the system. For analog spans it also
       provides a list of channels.

       By default it prints information about all the spans in the system.  However if parameters
       are provided, they will be considered to be a list of span numbers and information will be
       printed for them.

       Output is printed to the standard output. The format is that of an Asterisk  configuration
       file  (similar to a "ini" configuration file), where the name of the section is the number
       of the span. Note that the specifically for analog spans some keys may  appear  more  than
       once,  and  hence  you  can  not  use  a  parser for an "ini" format and assume you have a
       dictionary.

EXAMPLES

       Printing information for spans 1, 2 and 4:

         dahdi_scan 1 2 4

       And to print all the spans:

         dahdi_scan

       Information about a certain analog span:

         [5]
         active=yes
         alarms=OK
         description=Xorcom XPD #00/10: FXS
         name=XBUS-00/XPD-10
         manufacturer=Xorcom Inc.
         devicetype=Astribank: Unit 1 Subunit 0: FXS
         location=usb-0000:00:03.3-4
         basechan=125
         totchans=8
         irq=0
         type=analog
         port=125,FXS
         port=126,FXS
         port=127,FXS
         port=128,FXS
         port=129,FXS
         port=130,FXS
         port=131,FXS
         port=132,FXS

       And an example of a digital span:

         [1]
         active=yes
         alarms=RED
         description=T2XXP (PCI) Card 0 Span 1
         name=TE2/0/1
         manufacturer=Digium
         devicetype=Wildcard TE205P (4th Gen)
         location=Board ID Switch 0
         basechan=1
         totchans=24
         irq=193
         type=digital-T1
         syncsrc=0
         lbo=0 db (CSU)/0-133 feet (DSX-1)
         coding_opts=B8ZS,AMI
         framing_opts=ESF,D4
         coding=B8ZS
         framing=ESF

       The "type" field  may  contain:  "analog",  "digital-T1",  "digital-E1",  "digital-J1"  or
       "digital-BRI".

FILES

       Requires read access to /dev/dahdi/ctl .

BUGS

       The program still does not do everything described in the man page.

       It  also assumes that spans don't skip channel numbers, and that their channel numbers are
       "running". This is anyway almost always the case.  And always the case in  a  normal  boot
       process.
