	CAS Protocol		E&M Immed Strt	Channel Associated Signaling
			E&M Wink Start	(CAS) is a method of
			E&M Wink with	incorporating telephony
			dial tone	signaling info into an E1
			FXO Ground Strt	voice/data stream. In CAS, the
				signaling bits (the A, B, C, and
			FXO Loop Start
				D bits) are multiplexed into the
			FXS Ground Strt
				signal stream of each E1
			FXS Loop Start
				channel. (By contrast, in
			MFR2ITU
				Common Channel Signaling
			MFR2 China
				(CCS), one channel handles
			MFR2 ANI
				signaling for all other channels.)
				Each CAS protocol 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.
	FXS Options –		1 – 65535	Length of time before call
	No Response		(in seconds)	connection attempt is
	Timer			abandoned. Applicable only
				when FXS is selected as CAS
				protocol.
