		Appendix D: S-Register List
S41.......BOND TXFA	Specifies the number of seconds both endpoints at-
	tempt to detect the BONDING frame pattern when a
	call is connected before deciding the BONDING call
	has failed. When operating with other manufacturer's
	BONDING equipment, it may be necessary to length-
	en this timer to match TXADD01.
	0 to 256, 10 sec is default
S42.......BOND TXADD01	The number of seconds both endpoints waits for the
	additional call to be connected at the end of negotia-
	tion before determining the BONDING call has failed.
	When dialing overseas it may be necessary to length-
	en this timer to allow for lower call routing.
	0 to 256, 50 sec is default.
S43.......BOND TXDEQ	The number of seconds both endpoints attempt to
	equalize the network delay between the bearer chan-
	nels before determining the BONDING call has failed.
	0 to 256, 5 sec is default.
S44 ........BOND TANULL	The number of seconds the answering endpoint at-
	tempts to detect the BONDING negotiation pattern
	from the originating endpoint before aborting to clear
	channel mode. It may be necessary to shorten this
	timer if the DTE equipment connected to the ISU 2x64
	also has timer constraints for completing non-BOND-
	ING parameter negotiation.
	0 to 256, 10 sec is default.
S45.......BOND TCID	The number of seconds both endpoints attempt to ne-
	gotiate agreeable values for bearer channels and chan-
	nel capacities before determining the BONDING call
	has failed.
	0 to 256, 5 sec is default.
S46.......V25 MODE	Selects the type of V.25 bis dialing used.
	0	= Asynchronous V.25
	1	= HDLC V.25
	2	= BISYNC V.25
