misdn-init.conf

Bei der Installation von mISDN hatten wir bereits über den Aufruf /usr/sbin/misdn-init config die Konfigurationsdatei anlegen lassen.

/usr/sbin/misdn-init config
[OK] /etc/misdn-init.conf created. It's now safe to run "/usr/sbin/misdn-init start"
[ii] make your port (1) available in asterisk by editing "/etc/asterisk/misdn.conf"

Die beiden wichtigen Parameter für unsere Installation lauten:

• card=1,avmfritz
• te_ptmp=1

Mit ersterm wird festgelegt welche Karte verwendet wird. Der zweite Parameter gibt an, dass wir einen Mehrgeräteanschluss (point to multipoint) verwenden wollen und wir die Endstelle, also das Endgerät sind. Wolle man einen S0-Bus zur Verfügung stellen, müsste man hier als Option nt_ptmp setzen.

Die genaue Beschreibung der einzelnen Parameter entnimmt man am einfachsten der bestens dokumentierten Konfigurationsdatei:

#
# Card Settings
#
# Syntax: card=<number>,<type>[,<option>...]
#
#    <number>   count your cards beginning with 1
#    <type>     either 0x1,0x4 or 0x8 for your hfcmulti hardware,
#               or the name of your card driver module.
#    <option>   ulaw       - uLaw (instead of aLaw)
#               dtmf       - enable DTMF detection on all B-channels
#
#               pcm_slave  - set PCM bus into slave mode
#                            If you have a set of cards, all wired via PCM. Set 
#                            all cards into pcm_slave mode and leave one out.
#                            The left card will automatically be Master.
#
#               ignore_pcm_frameclock   - this can be set in conjunction with
#                                       pcm_slave. If this card has a  
#                                       PCI Bus Position before the Position 
#                                       of the Master, then this port cannot
#                                       yet receive a frameclock, so it must
#                                       ignore the pcm frameclock.
#                                        
#               rxclock    - use clocking for pcm from ST Port
#               crystalclock - use clocking for pcm from PLL (genrated on board)
#               watchdog   - This dual E1 Board has a Watchdog for 
#                            transparent mode

# Port settings

#
# Port Options
#
# Syntax: option=<port_number>,<option>[,<option>...]
#
#    <option>  master_clock  - use master clock for this S/T interface
#                              (only once per chip, only for HFC 8/4)
#              optical       - optical (only HFC-E1)
#              los           - report LOS (only HFC-E1)
#              ais           - report AIS (only HFC-E1)
#              slip          - report SLIP (only HFC-E1)
#              nocrc4        - turn off crc4 mode use double frame instead 
#                               (only HFC-E1)
#
# The master_clock option is essential for retrieving and transmitting
# faxes to avoid failures during transmission. It tells the driver to 
# synchronize the Card with the given Port which should be a TE Port and
# connected to the PSTN in general.

#
# General Options for your hfcmulti hardware
#
# poll=<number>
#
#        Only one poll value must be given for all cards.
#        Give the number of samples for each fifo process.
#        By default 128 is used. Decrease to reduce delay, increase to
#        reduce cpu load. If unsure, don't mess with it!!!
#        Valid is 32, 64, 128, 256.
#
# dsp_poll=<number>
#       This is the poll option which is used by mISDN_dsp, this might 
#       differ from the one given by poll= for the hfc based cards, since
#       they can only use multiples of 32, the dsp_poll is dependant on 
#       the kernel timer setting which can be found in the CPU section
#       in the kernel config. Defaults are there either 100Hz, 250Hz 
#       or 1000Hz. If your setting is either 1000 or 250 it is compatible
#       with the poll option for the hfc chips, if you have 100 it is 
#       different and you need here a multiple of 80.
#       The default is to have no dsp_poll option, then the dsp itself
#       finds out which option is the best to use by itself
#
# pcm=<number>
#        
#        Give the id of the PCM bus. All PCM busses with the same ID
#        are expected to be connected and have equal slots.
#        Only one chip of the PCM bus must be master, the others slave.
#
# debug=<number>
#
#        Enable debugging (see hfc_multi.h for debug options).
#
# dsp_options=<number>
#  
#       set this to 2 and you'll have software bridging instead of 
#       hardware bridging.
# 
#
# dtmfthreshold=<milliseconds>
#
#       Here you can tune the sensitivity of the dtmf tone recognizer.
#
# timer=<1|0>
# 
#       set this to 1 if you want hfcmulti to register at ztdummy (zaptel) 
#       and provide a 1khz timing source for it. This makes it possible
#       to have an accurate timing source for asterisk through zaptel from
#       hfcmulti to make applications like Meetme and faxing between wctdm
#       and hfcmulti work properly.
#
poll=128
dsp_poll=128
dsp_options=0
dtmfthreshold=100
