	CAS Protocol		E&M Immed Strt	Channel Associated Signaling
			E&M Wink Start	(CAS) is a method of incorporating
			E&M Wink with	telephony signaling info into an E1
			dial tone	voice/data stream. In CAS, the
			FXO Ground Strt	signaling bits (the A, B, C, and D
				bits) are multiplexed into the signal
			FXO Loop Start
				stream of each E1 channel. (By
			FXS Ground Strt
				contrast, in Common Channel
			FXS Loop Start
				Signaling (CCS), one channel
			MFR2ITU
				handles signaling for all other
			MFR2 China
				channels.) Each CAS protocol
			MFR2 ANI
				defines the states of the signaling
				bits during the various stages of a
				call (IDLE, SEIZED, ANSWER,
				RING-ON, RING-OFF).
				The CAS protocol code allows the
				VOIP to interact properly with the
				PBX or central-office switch that it
				serves. The need to download
				CAS protocols arises for only a
				small minority of VOIP users, and
				only when PBX/switch is found to
				be incompatible with standard
				protocols.
				Match this parameter to the setting
				of PBX or central-office switch.
