Field	Values	Description
Name
Red Alarm	Integer tally of	The alarm condition declared when a device
	alarms counted	receives no signal or cannot synchronize to the
	since last reset.	signal being received. A Red Alarm is
		generated if the incoming data stream has no
		transitions for 176 consecutive pulse positions.
Blue Alarm	Tally since last	Alarm signal consisting of all 1’s (including framing
	reset.	bit positions) which indicates disconnection or failure
		of attached equipment.
Loss of Frame	Tally since last	Loss of data frame synchronization.
Alignment	reset.
Excessive	Tally since last	Displayed value will increment if consecutive
Zeroes	reset.	zeroes beyond a set threshold are detected. I.e.,
		tally increments if more than 7 consecutive
		zeroes in the received data stream are detected
		under B8ZS line coding, or if 15 consecutive
		zeroes are detected under AMI line coding.
Status Freeze		Signaling has been frozen at the most
Signaling		recent values due to loss of frame
Active		alignment, loss of multiframe alignment or
		due to a receive slip.
Line		Line loopback deactivation signal has been
Loopback		detected in the receive bit stream.

Transmit Data		For use by MTS Technical Support
