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.
