AFT A108dm Firmware Change Log
===============================

Release V44
-----------
Dec 12 2011
Type:	Recommended A108dm Firmware
		Fixes unreliable front end framer read/write: on newer motherboards.
		New motherboards and new pci/pcie bridges have exposed a timing
		issue in front end framer read/write routines. This can cause
		corrupting in read/write routines causing T1/E1 framer to be misconfigured.

Release V43
-----------
Aug 24 2010
Type:	Recommended A108dm Firmware
		Fixes PCIe parity errors on some new Dell/HP/IBM servers causing 
   		PCI fatal error messages in the logs.
		Fixes the need for Windows to reboot after firmware update


Release V41
-----------
Feb 01 2010
Type:		Recommended A108dm Firmware
		Fixed PCIe dma timeouts.  On some new Dell/HP servers the PCIe timeouts
		on dma transactions were causing PCI fatal error messages
		in the logs.  This has now been fixed.



Release V40
-----------
Dec 23 2009
Type:		Recommended A108dm Firmware
		Added a framery sync sanity check.  This check is now used by the latest
		driver to monitor the health of the T1/E1 stream entering the FPGA.
		In case of a resync driver will ensure that timeslot sync is maintained.

		The latest driver 3.4.8/3.5.9 will use this hardware feature if its
		available. If the firmware does not have this feature, a front end OOF
		alarm will be used as a timeslot sync trigger.

Changes:	Firmware bug fix
		Recomended feature.

Release V39
-----------
Oct 07 2009
Type:		Recommended A108dm Firmware
		Bug fix on hw echo canceller. On some machines it was possible for
		echo canceller to start in a noisy mode. When in this mode all
		channels would have noise on them.

Changes:	Firmware bug fix
        This firmware fixes the hwec startup procedure.

Release V38
-----------
Aug 13 2009
Type:		Recommended A108dm Firmware
		New Feature: Added Free Running timer for Zaptel/Dahdi

Changes:	Firmware bug fix
		Fixes on potential pci parity errors on some systems.
		Fixes echo canceller H100 Errors that can occour on some systems.


Release V33
-----------
Sep 27 2007

Type:		Recommended A108dm Firmware for echo cancel cards
		Fixes issue with hardware echo canceller chip 
		security. 
		Supports DTMF detection without hardware echo
		cancellation operation.

Changes:	Firmware bug fix for echo canceller
		This bug can shut down the driver.

		Note: This bug only afected new Maxim AFT cards with HWEC.
		      DTMF detection only applies AFT cards with HWEC.

Release V31
-----------
Jul 10 2007

Type:           Mandatory A108dm Firmware for echo cancel cards 
		Fixes a serious bug with Echo Canceler operation.
		This bug caused a radom channel of echo canceler
		to become corrupted.

Changes:        Firmware bug fix for echo canceler
                This bug can cause hard crashes.

                Note: This bug only afected new Maxim AFT cards with HWEC.




Release V28
-------------
Nov 21 2006

Type: 		Mandatory for PCI Express Cards
		A serious bug exists in A108dm Firmware for PCI-E cards.
		On each front end access the next pci transaction can
		become corrupted, and if the next pci transaction is dma
		transaction, then an invalid memory can be written to.

Changes:	Firmware bug fix for PCI-E cards.
		This bug can cause hard crashes.
		
		Note: This bug only affects DATA operation of A108dm PCI
		Express Card. The TDM Voice operation is not affected.



Release V27
-------------
Sep 27 2006

Type:  		Mandatory
	        Reason this feature is mandatory for A108D is that it
		greatly reduces the CPU load.  With previous drivers/firmware
		A108D consumed too much cpu.

Changes:	This firmware release contains new feature:
		- Global TDM Voice Interrupt:
			It that combines all spans on a single
		   	interrupt. This significantly reduces cpu load.
		  
		  This option is only used in TDM Voice Mode.


Symptoms:	New Feature.

Compatibility:	This feature is actually backward compatible to older wanpipe driver releases.
		Meaning that if you install this firmware with pre beta8-2.3.4 release, the
		new feature will not be used, and the TDM Driver will work as before.
