Appendix A. AT Commands and S-Registers

S42 ... BOND	The number of seconds both endpoints wait for
TXADD01	the additional call to be connected at the end of
	negotiation before deciding the async BOND-
	ING 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 attempt to equalize the network delay between 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 endpoint attempts to detect the Async BONDING negotia- tion 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 Express XR/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 attempt

to negotiate agreeable values for bearer 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 service.

0= AT&T 5ESS

1= Northern Telecom DMS-100

2= National ISDN-1

S53 ...	CALL TYPE	Call type (Dial service only).
		0	= Speech
		1	= Audio
		2	= 56 Kbps data
		3	= 64 Kbps data
S54 ...	PROTOCOL	Rate adaption protocol type.
	TYPE	2	= Async BONDING
		6	= V.120
		11	= FALLBACK
		12	= PPP async-to sync conversion
