Table 3-1 Front Panel Controls and Indicators (Cont.)

Name	Type	ITU Circuit	Function
DCD	Yellow LED	109	On when the local and remote modems are in sync, and the
			section 6 of the internal SW6 switch is set to ON.
			On when the local and remote modems are in sync, and the
			section 6 of the internal SW6 switch is set to OFF, and the RTS at
			the remote modem is ON.
LOS	Red LED		On when loss of synchronization occurs between the local and
			remote modem.
ERR	Red LED		On when an error occurs in the configuration received from the
			master unit.
TEST	Red LED		On when a test is active.

		3.2	Operating Instructions
Turning ASMi-31		ASMi-31 turns on as soon as power is connected. When power is
On		connected, the PWR indicator lights up and remains lit as long as ASMi-31
		receives power.
Normal LEDs		Check that the other front panel LEDs appear as listed in Table 3-2.This
Indications		indicates that the local and remote ASMi-31 units are operational and
		passing data.
		Table 3-2 ASMi-31 Controls and Indicators – Normal Operation
	Name		State	Function
	PWR		On
	TD		On or blinking	Flashing depends upon the data being transmitted.
	RD		Off or blinking	Flashing depends upon the data being received.
	RTS			Lights when RTS status is On
	DCD			Lights when RTS is received from the remote
				modem and the modems are synchronized
				(DCD - OFF - switch SW6)
	LOS		On or blinking	Blinks until synchronization between the modems
				is achieved.
				Constantly On when there is no synchronization.
	ERR		Off or blinking	Blinks until synchronization between the modems
				is achieved.
	TEST		On or blinking	Blinks until synchronization between the modems
				is achieved.
				Constantly On while test is activated from either
				local or remote unit.
