Appendix D. S-Register List

S11 FALLBACK DEFAULT Determines how the ISU 128 answers an incoming call if all of the protocols in Fallback failed.

1= Clear Channel

2= BONDING Mode 1

3= SAP

4= T-link

5= V.110

6= V.120

7= V.34

8= DSU 57.6 Async (default)

9= PPP asyn-syn

S12	ESCAPE TIME	Determines the delay required immediately before
		and after entering the escape command for the ISU 128
		to recognize and 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 ISU 128.
		Bit 3	=	1: Disables AT responses from the ISU 128.
		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: Disables PPP ACCM Spoofing.
		Bit 7	=	0: Enables PPP ACCM Spoofing.
		Bit 8	=	1: Ring indicator uses cadence.
		Bit 8	=	0: Ring indicator remains on.
S15	ASYNC BONDING	0 = ADTRAN Only
		1 = Multi-Vendor
S22	MSG BITS	Miscellaneous message bits (Bit 8 is most significant
		bit).
		Bit 5	=	Bit 6 =	Bit 7 = 1 : Allows connect message
					with baud rate.
		Bit 5	=	Bit 6 =	Bit 7 = 0 : Connects message without
					baud rate.
S24	V120 LLC	Value determines whether the V.120 bit is set in setup
		message for CCITT V.120 calls. Some terminal adapters
		require this bit be set to connect V.120 calls.

0= Set V.120 bit in call setup message. (default)

1= Do not set V.120 bit in call setup message.
