SYNOPSIS

       zeitansage -k <kanal/channel> -c hw:0,0 [options] [station_id]

   Global options:
       -h --help

              This help

       --config [~/]<path to config file>

              Give  a config file to use. If it starts with '~/', path is at home dir.  Each line
              in  config  file  is  one  option,  '-'  or  '--'  must  not  be  given!   Default:
              '~/.osmocom/analog/zeitansage.conf'

       --no-config

              Even if a config file exists, don't use it.

       -v --verbose <level> | <level>,<category>[,<category>[,...]] | list

              Use  'list'  to  get  a list of all levels and categories.  Verbose level: digit of
              debug level (default = '3') Verbose level+category: level digit followed by one  or
              more categories -> If no category is specified, all categories are selected

       -v --verbose date

              Show date with debug output

       -k --kanal <channel>

       -k --channel <channel>

              Channel (German = Kanal) number of "Sender" (German = Transceiver)

       -a --audio-device hw:<card>,<device>[/hw:<card>.<rec-device>]

              Sound  card  and  device  number  (default  = 'hw:0,0') You may specify a different
              recording device by using '/'.  Don't set it for SDR!

       -s --samplerate <rate>

              Sample rate of sound device (default = '48000')

       -i --interval 0.1..25

              Interval of processing loop in ms (default = '1.0' ms) Use 10 to drastically reduce
              CPU usage. In case of buffer underrun, increase buffer accordingly.

       -b --buffer <ms>

              How  many  milliseconds are processed in advance (default = '50') A buffer below 10
              ms requires low interval like 0.1 ms.

       -p --pre-emphasis

              Enable pre-emphasis, if you directly connect to the oscillator of the  transmitter.
              (No pre-emphasis done by the transmitter.)

       -d --de-emphasis

              Enable  de-emphasis,  if you directly connect to the discriminator of the receiver.
              (No de-emphasis done by the receiver.)

       --rx-gain <dB>

              Raise/lower receiver's RX level by given gain in dB.  (Works with sound card only.)

       --tx-gain <dB>

              Raise/lower transmitters's RX level by given gain in dB.  (Works  with  sound  card
              only.)

       -e --echo-test

              Use  echo  test,  to send back audio from mobile phone's microphone to the speaker.
              (German: 'Blasprobe').

       -c --call-device hw:<card>,<device>[/hw:<card>.<rec-device>]

              Sound card and device number for headset (default = '') You may specify a different
              recording device by using '/'.

       --call-samplerate <rate>

              Sample rate of sound device for headset (default = '48000')

       --call-buffer <ms>

              How many milliseconds are processed in advance (default = '50')

       -x --osmocc-cross

              Enable  built-in  call  forwarding  between  mobiles.  Be sure to have at least one
              control  channel  and  two  voice  channels.   Alternatively   use   one   combined
              control+voice channel and one voice channels.

       -o --osmocc-sock

              Disable built-in call control and offer socket

       --cc "<osmo-cc arg>" [--cc ...]

              Pass arguments to Osmo-CC endpoint. Use '-cc help' for description.

       --no-l16

              Disable L16 (linear 16 bit) codec.

       -t --tones 0 | 1

              Connect  call  on  setup/release  to  provide  classic  tones towards fixed network
              (default = '1')

       -l --loopback <type>

              Loopback test: 1 = internal | 2 = external | 3 = echo

       -r --realtime <prio>

              Set prio: 0 to disable, 99 for maximum (default = 0)

       --fast-math

              Use fast math approximation for slow CPU / ARM based systems.

       --write-rx-wave <file>

              Write received audio to given wave file.

       --write-tx-wave <file>

              Write transmitted audio to given wave file.

       --read-rx-wave <file>

              Replace received audio by given wave file.

       --read-tx-wave <file>

              Replace transmitted audio by given wave file.

   Network specific options:
       -G --gain

              Gain of audio level relative to 1 mW on a 600 Ohm line. (default = -16)

       -A --alerting

              Play as early audio while alerting. Don't send a connect.

       Press digits '0'..'9' and then 'd' key to dial towards mobile station.  Press 'h'  key  to
       hangup.  Press 'w' key to toggle display of RX wave form.  Press 'c' key to toggle display
       of channel status.  Press 'm' key to toggle display of measurement value.

                                                                                    zeitansage(1)
