xpp: a massive backport from DAHDI. From Xorcom branch-rel-6839-r6908 .
Sun Mar 1 2009 Oron Peled <oron@actcom.co.il> - xpp.r6795
* Fix cases where the command_queue overflowed during initialization.
- Also add a 'command_queue_length' parameter to xpp.ko
* More migrations to sysfs:
- Add a 'transport' attribute to our astribank devices which
points to the usb device we use. E.g:
/sys/bus/astribanks/devices/xbus-00/transport is symlinked to
../../../../../../devices/pci0000:00/0000:00:10.4/usb5/5-4
- Move /proc/xpp/XBUS-??/XPD-??/span to
/sys/bus/xpds/devices/??:?:?/span
- Migrate from /proc/xpp/sync to:
/sys/bus/astribanks/drivers/xppdrv/sync
- New 'offhook' attribute in:
/sys/bus/xpds/devices/??:?:?/offhook
* PRI: change the "timing" priority to match the convention used by
other PRI cards -- I.e: lower numbers (not 0) have higher
priority.
* FXO:
- Power denial: create two module parameters instead of hard-coded
constants (power_denial_safezone, power_denial_minlen).
For sites that get non-standard power-denial signals from central
office on offhook.
- Don't hangup on power-denial, just notify Dahdi and wait for
- Fix caller-id detection for the case central office sends it before
first ring without any indication before.
Asterisk's desicion.
Mon, Dec 8 2008 Oron Peled <oron@actcom.co.il> - xpp.r6430
* PRI:
- Match our span clocking priorities (in system.conf)
to Digium -- this is a reversal of the previous state.
Now lower numbers (greater than 0) are better.
- Synchronization fixes for PRI ports other than 0.
- Fix T1 CRC for some countries (e.g: China).
* FXS: fix bug in VMWI detection if using old asterisk
which does not provide ZT_VMWI ioctl().
* FXO:
- Improve caller_id_style module parameter. This provide a workaround
for countries that send this information without any notification
(reverse polarity, ring, etc.)
- Don't force on-hook upon power-denial. So, loopstart devices
would ignore these as expected.
* Implement a flow-control to prevent user space (init_card_* scripts)
from pressuring our command queue.
