Appendix A. AT Commands and S-Registers

S41	BOND TXFA	Specifies the number of seconds both end-
		points attempt to detect the async BOND-
		ING frame pattern when a call is connected
		before deciding the async BONDING call
		has failed. When operating with other man-
		ufacturer's async BONDING equipment it
		may be necessary to lengthen this timer so
		that it matches TXADD01.
		0 to 255, 10 sec is default.
S42	BOND TXADD	The number of seconds both endpoints wait
		for the additional call to be connected at the
		end of negotiation before deciding the async
		BONDING call has failed. When dialing
		overseas it may be necessary to lengthen this
		timer to allow for slower call routing.
		0 to 255, 50 sec is default
S43	BOND TXDEQ	The number of seconds both endpoints at-
		tempt to equalize the network delay be-
		tween the bearer channels before deciding
		the Async BONDING call has failed.
		0 to 255, 50 sec is default
S44	BOND TANULL	The number of seconds the answering end-
		point attempts to detect the Async BOND-
		ING negotiation pattern from the
		originating endpoint before aborting to clear
		channel mode. It may be necessary to short-
		en this timer if the DTE equipment connect-
		ed to the Express XRT also has timer
		constraints for completing non-BONDING
		parameter negotiation.
		0 to 255, 10 sec is default
S45	BOND TCID	The number of seconds both endpoints at-
		tempt to negotiate agreeable values for bear-
		er channels and channel capacities before
		deciding the async BONDING call has
		failed.
		0 to 255, 5 sec is default
S52	SWITCH TYPE	Selects the network switch type for dial ser-
		vice.
		0=AT&T 5ESS
		1=Northern Telecom DMS-100
		2=National ISDN-1
		3=NEC
		4-EuroISDN
