ADTRAN XRT S15 ... Async ................ Asynchronous Bonding method, S25, S27, S30, S31

Appendix A. AT Commands and S-Registers

execute the command. Range = 0 to 127

S14 ... MISC BITS ......... Miscellaneous bits (bit 8 is most significant bit).

	Bit 2	= 1: Enables on screen echo of AT commands.
	Bit 2	= 0: Disables on screen echo of AT
		commands.
	Bit 3	= 0: Enables AT responses from the
		Express XR/XRT.
	Bit 3	= 1: Disables AT responses from the
		Express XR/XRT.
	Bit 4	= 1: Enables AT responses to be displayed
		in text form.
	Bit 4	= 0: Enables AT responses to be displayed
		in numeric form.
	Bit 7	= 1: Disable PPP ACCM spoofing.
	Bit 7	= 0: Enable PPP ACCM spoofing.
	Bit 8	= 1: Ring indicator uses cadence.
	Bit 8	= 0: Ring indicator remains on.
S15 ... ASYNC ................ Asynchronous BONDING method.
BONDING	0 = ADTRAN revision 0 (default)
	1 = Multi-vender option
S22 ... MSG BITS .......... Miscellaneous message bits (bit 8 is most
	significant bit).
	Bit 5	= Bit 6 = Bit 7 = 1 Allows connect mes-
		sage with baud rate.
	Bit 5	= Bit 6 = Bit 7 = 0 Connect message
		without baud rate.

S25	... DTR DETECT .... Determines time, in hundredths of a second, that
	TIME	must elapse before the Express XR/XRT recog-
		nizes a change in DTR.
		Range = 0 to 255
S27	... PPP MODE ......... Value determines whether or not PPP will be a
		single-link or multilink connection.
		0	= Single-link operation (default)
		1	= Multilink operation
		2	= Use compression
S30	... DTE CTS	Controls the operation of the DTE connector
		CTS line.
		0	= Follows RTS
		1	= Force CTS
S31	... DTE RTS	Controls operation of the RTS line.
