SW0			• Uses the internal clock as the	receive
		ON	clock when the No. 0 Port is synchro-
			nous.
	5		• When the No. 0 Port is asynchronous.
	Note 4
			Enables receive clock from the DCE (Mo-
		OFF	dem) side when the No. 0 Port is synchro-
			nous. (Clock is received at the RXC
			terminal)
			Set No. 0 port forcibly in a state which DSR
		ON	signal is always provided. Force DSR sig-
	6		nal high for port 0. No SMDR buffering.
	Note 5
			Receive DSR signal from the DCE on No.
		OFF	0 port. Detect DSR signal from DCE for
			port 0. Allows SMDR records to buffer.
			Set No. 1 port forcibly in a state which DSR
		ON	signal is always provided. Force DSR sig-
	7		nal high for port 1. No SMDR buffering.
	Note 5
			Receive DSR signal from the DCE on No.
		OFF	1 port. Detect DSR signal from DCE for
			port 1. Allows SMDR records to buffer.
			Set No. 2 port forcibly in a state which
		ON	DSR signal is always provided. Force DSR
	8		signal high for port 2. No SMDR buffering.
	Note 5
			Receive DSR signal from the DCE on No.
		OFF	2 port. Detect DSR signal from DCE for
			port 2. Allows SMDR records to buffer.

The figure in the SWITCH NAME column and the position in in the SETTING POSITION col- umn indicate the standard setting of the switch. When the switch is not set as shown by the figure and , the setting of the switch varies with the system concerned.
