Front Panel Configuration Options

	Parameter &
326X Menu	Option	Description
ACU OPT’S	ACU Select	Determines which Auto-Call Unit (ACU) the modem uses. To enable SDC: select an ACU
		(ACU Select), a bit-synchronous data format (for the AT and V.25bis ACUs), and
	=AT	Mode=Reliable, Auto Reliable, or Speed Auto Reliable (AT*SM).
		The AT auto-call unit is used.
		To enable SDC: after selecting AT ACU, select a data format (AT&M). The options are: Sync
		Data, DTR Dial, or Man Dial. Refer to the AT&M option description in Table A-1.
	:V25b	The V.25bis auto call unit is used.
		To enable SDC: after selecting V25b, select a data format (AT&M). The options are: AsynSync
		or Bitsync (see next parameter, below).
	:LPDA2	The LPDA-2 auto-call unit is used.
		After selecting LPDA (LPDA transmits data synchronously), to enable SDC, select
	:None	Mode=Reliable, Auto Reliable, or Speed Auto Reliable (AT*SM).
		No auto call unit is used.
		To enable SDC: after selecting None, choose a synchronous data format using the NoACU Form
		option (discussed later in this table).
	V25Form	Determines the format of data when the ACU Select option is set to V25b.
		To enable SDC: after selecting V.25bis ACU, choose one of the synchronous data formats
		(AsynSync or Bitsync). Select Mode=Reliable, Auto Reliable, or Speed Auto Reliable
		(AT*SM).
	=Async	Modem is compatible with asynchronous DTEs.
	: AsynSync	Modem dials calls asynchronously, but data is passed synchronously.
	:Bitsync	The DTE uses the bit-synchronous, HDLC-like protocol outlined in the ITU V.25bis
		specification.
	: Charsync	The DTE uses the character-synchronous protocol outlined in the ITU V.25bis specification.
		NOTE: Charsync is not available for the SDC operating mode.
	NoAcu Form	This option determines the format of data when ACU Select=off.
		To enable SDC: after selecting ACU Select=None, choose NoAcu Form=Sync. Select
		Mode=Reliable, Auto Reliable, or Speed Auto Reliable (AT*SM).
	=Async	Asynchronous data is passed in data mode.
	:Sync	Synchronous data is passed in data mode.
	Char Length	Applies to asynchronous data applications that use the direct data transfer mode (no error
		correction). The modem ignores this option in the normal, reliable, or auto-reliable data transfer
		modes.
		Do not change this option unless your application requires it. If you must change it, select the
		option that corresponds to the number of bits that your DTE uses to code a character (start bit,
		data bits, parity bit, and stop bit) NOTE: Autobauding works only with 10-bit characters.
	=8	Modem is compatible with 8-bit characters.
	:9	Modem is compatible with 9-bit characters.
	:10	Modem is compatible with 10-bit characters.
	:11	Modem is compatible with 11-bit characters.
	V25 Char	Determines the type of character the V.25bis ACU uses.
	=ASCII	The V.25bis ACU uses ASCII character format.
	:EBCDIC	The V.25bis ACU uses EBCDIC character format.

Gray shading indicates country-specific options. See Appendix C for your country’s options.
