Summary:                    a driver for single-port FXO cards based on Si3052
chip + Si3011/17/18 DAA (Motorola 52-6116-2A, PM560MS etc.)
Description: 
Attached here is a driver for single-port FXO cards based on Si3052 chip +
Si3011/17/18 DAA. They are marketed as Motorola 52-6116-2A, PM560MS and
many others.
Driver is written from scratch to take advantage of international features
some of the DAAs have. There is also patch for wcfxo module to support
these cards circulating on Net, but it runs the card in
backwards-compatible mode and doesn't allow most of the POTS settings to be
tweaked. 

Tested features:
* Sending and receiving voice,
* Ringer detection and validation,
* DTMF detection,
* Caller ID reception (only ETSI FSK mode tested, but different ones
should work too in principle),
* ULAW/ALAW mode,
* Busy pattern hangup detecion,
* Line disconnection detection (only when offhook due to hardware
limitation).

Usage:
* Put fxo_si3052.c and fxo_si3052.h files in drivers/dahdi directory of
dahdi-linux package,
* Add "obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCFXO) += fxo_si3052.o" line
(without quotes) to Kbuild file in the same directory (drivers/dahdi) near
the top of the file.
* Patch fxo_modes.h file in the same directory with
dahdi_fxo_modes_si3052.patch (command: "patch -p0
<dahdi_fxo_modes_si3052.patch" w/o quotes).
* Compile and install dahdi-linux package as usual.
* Patch dahdi-tool package with dahdi-gencfg.patch (command: "patch -p0
<dahdi-gencfg.patch" w/o quotes).
* Compile and install dahdi-tools package as usual.
* Load required modules (including fxo_si3052). For fxo_si3052 you have to
set the region name to one of those listed in fxo_modes.h file (this file
is also used for wctdm driver, so region names are the same). For example:
"modprobe fxo_si3052 region_param=ARGENTINA" (w/o quotes) would load the
module with proper settings for Argentina. Also add "use_ulaw=1" if you
plan to use ULAW instead of ALAW (default).
* Generate config file for the card with dahdi_genconf, configure with
dahdi_cfg, write config files for Asterisk, all just like with the wcfxo
driver.

If CallerID detection doesn't work the problem might be with too long
minimum ringer time. Default is 512ms, but sometimes first ring signal is
shorter and is not detected as ring, so CallerID detection is not started
by Asterisk. In this case check ringer length and add appropriate
"min_ringer_time" parameter (for example "min_ringer_time=150" for 150ms).
Valid values are 100, 150, 200, 256, 384, 512 and 1024 ms.
 
Comments and suggestions are welcome.
