Black Box 5000 manual DLC To DTE

CHAPTER 9: Data-Channel Configuration

Table 9-3. Sync Channel Characteristics (continued)

Option	Protocol	Default	Description
Interface	DLC	TO DTE	Set TO DTE for interfacing with data terminal
Type	ASCII Bisync	TO DTE	equipment. The channel will return CTS on in
	EBCDIC Bisync	TO DTE	response to RTS on from the attached terminal
	H-P Sync	TO DTE	equipment. Set TO DCE for interfacing with data
	RTS/CTS	TO DTE	communications equipment. The interface signal
	Sync-Pad	TO DTE	CTS must be on from the attached modem in order
	MICOM DLC	TO DTE	to enable output from the Multiserver. This also
	MICOM Voice	TO DTE	allows for RTS/CTS delay, which varies on different
	TDM	TO DTE	modems. Each port must be configured
			independently at each end of the link. This will
			allow, for example, the flexibility for a TO DTE
			interface to a computer and for a TO DCE interface
			to a tail-circuit modem. If CTS buffer control is
			selected, CTS may be delayed up to 250 ms after
			RTS. See Tables 9-6and 9-7for pin assignments
			and DCE and DTE local channel interfaces.
Carrier	DLC	CONSTANT	Defines when carrier is held high, either constant or
Mode	ASCII Bisync	CONSTANT	variable. (TDM is set for constant and is not
	EBCDIC Bisync	CONSTANT	configurable.)
	H-P Sync	CONSTANT
	RTS/CTS	VARIABLE
	Sync-Pad	CONSTANT
	MICOM DLC	CONSTANT
	MICOM Voice	CONSTANT
Sync	ASCII Bisync	16	Sets the value (in hexadecimal) of the leading sync
Character*	EBCDIC Bisync	32	character for the start of the block (usually 16 or
	H-P Sync	16	32). This character is repeated twice.
	RTS/CTS	FF	It is very important that the correct sync character
	Sync-Pad - 1	16	be configured; otherwise false syncing may occur.
	- 2	16	For Sync-Pad Protocol, the sync character must
	Fast Packet	FF	match the 16-bit hexadecimal synchronization
	TDM	FF	sequence.
Number of	ASCII Bisync	3	Sets number of leading sync characters the
Leading	EBCDIC Bisync	3	Multiserver will generate on output. This provides a
Syncs*	H-P Sync	3	time delay to allow the device on the selected port
	RTS/CTS	3	to synchronize.
	Sync-Pad	3
Pad	ASCII Bisync	FF	Sets the value of the pad character (any alpha or
Character*	EBCDIC Bisync	FF	numeric character). The pad character precedes
	H-P Sync	FF	the sync character and follows the end of the block.
	RTS/CTS	FF	The pad character is used to pad the block of data.
	Sync-Pad	FF
