-DKMS
-~~~~
-DKMS, Dynamic Kernel Module Support, is a framework for building Linux
-kernel modules. It is used, among others, by several distributions that
-package the DAHDI kernel modules.
-
-DKMS is designed to provide updates over drivers installed from original
-kernel modules tree. Thus it installed modules into /lib/modules/updates
-or /lib/modules/VERSION/updates . This is generally not an issue on
-normal operation. However if you try to install DAHDI from source on
-a system with DAHDI installed from DKMS this way (potentially of an
-older version), be sure to remove the DKMS-installed modules from the
-updates directory. If you're not sure, the following command will give
-you a clue of the versions installed:

-  find /lib/modules -name dahdi.ko

-See <<_span_assignments,Span Assignments>> below.
-
-XPP (Astribank) module parameters
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-==== debug
-(all modules) - see above.
-
-==== dahdi_autoreg
-(xpp)
-
-Register spans automatically (1) or not (0). Default: 0.
-Setting it simplifies operations with a single Astribank and no other
-DAHDI hardware. However if you have such systems, automatic
-registration can cause the order of spans to be unpredictable.
-The standard startup scripts use 'dahdi_registration on' instead of this.
-
-==== tools_rootdir
-(xpp)
-
-Defaults to /. Passed (as the variable DAHDI_TOOLS_ROOTDIR) to generated
-events (which can be used in udev hooks). Also serves as the base of
-the variable DAHDI_INIT_DIR (by default: $DAHDI_TOOLS_DIR/usr/share/dahdi).
-
-==== initdir
-(xpp)
-
-Deprecated. Setting both initdir and tools_rootdir will generate an error.
-
-A directory under tools_rootdir containing the initialization scripts.
-The default is /usr/share/dahdi .
-Setting this value could be useful if that location is inconvenient for you.
-
-==== rx_tasklet
-(xpp)
-
-Enable (1) or disable (0) doing most of the packets processing in
-separate tasklets. This should probably help on higher-end systems with
-multiple Astribanks.
-
-==== vmwi_ioctl
-(xpd_fxs)
-
-Does userspace support VMWI notification via ioctl? Default: 1 (yes).
-
-Disable this (0) to have the driver attempt to detect the voicemail
-message waiting indication status for this port from FSK messages
-userspace (Asterisk) sends. Set the ports to use AC neon-lamp style
-message waiting indication. The detection from the FSK messages takes
-extra CPU cycles but is required with e.g. Asterisk < 1.6.0 .
-
-Also note that in order for this parameter to take effect, it must be
-set before the span is registered. This practically means that it
-should be set through modprobe.d files.
-
-See also Voicemail Indication in README.Astribank.
-
-==== usb1
-(xpp_usb)
-
-Enable (1) or disable (0) support of USB1 devices. Disabled by default.
-
-USB1 devices are not well-tested. It seems that they don't work at all
-for Astribank BRI. Generally they should work with the current code, but
-we expect the voice quality issues. Hence we would like to make it
-very clear that you if you have a USB1 port (rather than a USB2 one, as
-recommended) you will have to take an action to enable the device.
-
-==== poll intervals
-(various)
-
-There are various values which the driver occasionally polls the
-device for. For instance, the parameter poll_battery_interval for
-xpd_fxo to poll the battery, in order to know if the telco line is
-actually connected.
-
-The value of those parameters is typically a number in milliseconds.
-0 is used to disable polling. Under normal operation there should be
-no reason to play with those parameters.
-
-==== dtmf_detection
-(xpd_fxs)
-
-Enable (1) or disable (0) support of hardware DTMF detection by the
-Astribank.
-
-==== caller_id_style
-(xpd_fxo)
-
-Various types of caller ID signalling styles require knowing the PCM
-even when the line is on-hook (which is usually a waste of CPU and
-bandwidth). This parameter allows fine-tuning the behaviour here:
-
-* 0 (default) - Don't pass extra PCM when on-hook.
-* 1 ETSI-FSK: Wait for polarity reversal to come before a ring and
-  then start passing PCM until the caller ID has been passed.
-* 2 ETSI-DTMF: Always pass PCM and generate a DTMF if polarity reversal is
-  detected before ring.
-* 3 Passthrough: Always pass PCM as-is.
-
-This parameter is read-only. It cannot be changed at run-time.
-
-==== battery_threshold
-(xpd_fxo)
-
-Minimum voltage that shows there is battery. Defaults to 3. Normally you
-should not need to change this, unless dealing with a funky PSTN
-provider.
-
-==== battery_debounce
-(xpd_fxo)
-
-Minimum interval (msec) for detection of battery off (as opposed to e.g.
-a temporary power denial to signal a hangup). Defaults to 1000. As with
-battery_threshold above, there's normally no need to tweak it.
-
-==== use_polrev_firmware
-(xpd_fxo)
-
-Enable (1, default) or disable (0) support for polarity reversal
-detection in the hardware. Only has effect with PIC_TYPE_2.hex rev. >=
-11039 and with the initialization changes (init_card_2_30) in rev.
-949aa49.
-
-This parameter is read-only. It cannot be changed at run-time.

-Span Assignments
-~~~~~~~~~~~~~~~~
-A DAHDI device (e.g. a PCI card) is represented within the DAHDI drivers
-as a 'DAHDI device'. Normally (with auto_assign_spans=1 in the module
-dahdi, which is the default), when a device is discovered and loaded,
-it registers with the DAHDI core and its spans automatically become
-available. However if you have more than one device, you may be
-interested to set explicit spans and channels numbers for them. To use
-manual span assigment, set 'auto_assign_spans' to 0 . e.g. in a file
-under /etc/modprobe.d/ include the following line:
-
-  options dahdi auto_assign_spans=0
-
-You will then need to assign the spans manually at device startup. You
-will need to assign a span number and channel numbers for each
-available span on the system. On my test system I have one BRI PCI card
-and one Astribank BRI+FXS:

-  echo 3:2:5  >/sys/bus/dahdi_devices/devices/astribanks:xbus-00/assign_span

-under /dev/dahdi. The name is 'dahdi!foo' for the file '/dev/dahdi/foo'
-(udev translates exclamation marks to slashes). Those nodes are not, for
-the most part, proper SysFS nodes, and don't include any interesting
-properties.
-
-
-Devices Bus
-^^^^^^^^^^^
-Each DAHDI device (a physical device, such as a PCI card) is represented
-by a node under /sys/bus/dahdi_devices/devices named with the name of
-its device.
-
-Its attributes include:
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/assgin-span
-Write-only attribute: this device's spans should now be assigned
-("registered"). See section about <<_span_assignments>>.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/auto-assign
-Write-only attribute. Spans in the device auto-assign ("register" as in
-the original interface). See section about <<_span_assignments>>.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/hardware_id
-A unique hardware-level identifier (e.g. serial number), if available.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/manufacturer
-The name of the manufacturer. Freeform-string.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/spantype
-A line for each available span: <num>:<type>. This has to be provided
-here as in the case of manual assignment, userspace may need to know
-it before span nodes are created.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/spantype
-Device type.
-
-===== /sys/bus/dahdi_devices/devices/DEVICE/unassign-span
-Write-only attribute: the span whose device-local number is written
-should now be unassigned ("unregistered"). See section about
-<<_span_assignments>>.
-
-
-Spans Bus
-^^^^^^^^^
-Each DAHDI span is represented by a node under
-/sys/bus/dahdi_spans/devices with the name 'span-N' (where N is the
-number of the span). Spans of each device also reside under the node of
-the device.
-
-Useful attributes in the span node:
-
-===== /sys/bus/dahdi_spans/devices/span-N/alarms
-The alarms of the span. Currently this is a numeric representation.
-This may change in the future.
-
-===== /sys/bus/dahdi_spans/devices/span-N/basechan
-The channel number of the first channel. The channel numbers of the
-following channels are guaranteed to follow it.
-
-===== /sys/bus/dahdi_spans/devices/span-N/channels
-The number of the channels in the span.
-
-===== /sys/bus/dahdi_spans/devices/span-N/desc
-A free-form description of the span.
-
-===== /sys/bus/dahdi_spans/devices/span-N/is_digital
-1 if the span is digital, 0 if it isn't.
-
-===== /sys/bus/dahdi_spans/devices/span-N/is_sync_master
-1 if the span is the sync master, 0 if it isn't.
-
-===== /sys/bus/dahdi_spans/devices/span-N/lbo
-LBO setting for the channel.
-
-===== /sys/bus/dahdi_spans/devices/span-N/lineconfig
-The framing and coding of the span, for a digital span. Textual
-represenation:
-
-<B8ZS|AMI|HDB3>/<D4|ESF|CCS>[/CRC4]
-
-===== /sys/bus/dahdi_spans/devices/span-N/local_spanno
-The number of the span within the DAHDI device.
-
-===== /sys/bus/dahdi_spans/devices/span-N/name
-A concise name for this span.
-
-===== /sys/bus/dahdi_spans/devices/span-N/spantype
-A very short type string.
-
-===== /sys/bus/dahdi_spans/devices/span-N/syncsrc
-Current sync source.
-
-==== sys/bus/dahdi_spans/drivers/generic_lowlevel/master_span
-All spans in the bus are handled by a single driver. The driver has one
-non-standard attribute: master_span. printing it shows the current DAHDI
-master span writing a number to it forces setting this span as the master
-span.
-
-
-Channels Bus
-^^^^^^^^^^^^
-Each DAHDI channel is represented by a node under
-/sys/bus/dahdi_channels/devices with the name 'dahdi!channels!N!M'
-(where N is the number of the span and M is the number of the channel
-in the span - chanpos). Channels of each span also reside under the node
-of the span.
-
-Useful attributes in the channel node (All attributed listed below are
-read-only):
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/alarms
-List of names of the current active alarms (space separated). Normally
-(no alarms) empty. Example:
-
-  RED YELLOW
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/blocksize
-The block size set by userspace.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/channo
-The (global) channel number.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/chanpos
-The channel number within the span.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/dev
-Major and minor device numbers.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/ec_factory
-The name of the echo canceller to be used in the channel, if one is
-configured. Example:
-
-  MG2
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/ec_state
-State of the echo canceller. ACTIVE: configured and inuse. INACTIVE
-otherwise.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/in_use
-1 if the channel is in use (was opepend by userspace), 0 otherwise.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/name
-A name string for the channel
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/sig
-The signalling types set for the channel. A space-separated list of
-signalling types.
-
-===== /sys/bus/dahdi_spans/devices/span-N/dahdi!channels!N!M/sigcap
-The signalling types this channel may be configured to handle. A space-
-separated list of signalling types.
