	Table 4-2
	Health and Status Messages
Message	Description
LOS at Net	A Loss Of Signal condition (declared after 175 consecutive zeros) has been detected on the
	network interface. The condition is cleared when the density of ones to zeros received is 12.5%.
LOS at DTE	A Loss Of Signal condition has been detected on the DTE Drop/Insert interface. The condition is
	cleared when the density of ones to zeros received is 12.5%.
OOF at Net	An Out Of Frame condition (3 consecutive errored frame alignment events or, in CRC4 mode, a
	lack of multiframe alignment) has been detected on the network interface. The condition is cleared
	when a reframe occurs.
OOF at DTE	An Out Of Frame condition has been detected on the DTE Drop/Insert interface. The condition is
	cleared when a reframe occurs.
AIS at Net	An Alarm Indication Signal (unframed all ones signal) is being received by the network interface.
AIS at DTE	An Alarm Indication Signal is being received by the DTE Drop/Insert interface.
EER at Net	An Excessive Error Rate condition has been detected on the network interface (the bit error rate
	is 10E-3 or greater for 5 seconds). The condition is cleared when the error rate falls below the
	threshold value (10E-4) for 5 seconds.
RAI at Net	A Remote Alarm Indication is being received by the network interface.
RAI at DTE	A Remote Alarm Indication is being received by the DTE Drop/Insert interface.
Primary Clk fail	The primary clock has failed. Timing for the E1 DSU/CSU is provided by the secondary clock.
Second Clk fail	The primary clock and the secondary clock have failed. Timing for the E1 DSU/CSU is provided by
	the internal clock.
OOF at Prtn	An Out Of Frame has been detected on data port Prtn (where n is the port number: 1±2 for the
	3172, or 1±4 for the 3174). This condition only occurs if the synchronous data port's Embedded
	Data Link (EDL) is enabled.
EER at Prtn	The error rate of the received signal has exceeded the configured threshold for data port Prtn
	(where n is the port number: 1±2 for the 3172, or 1±4 for the 3174). This condition only occurs if
	the synchronous data port's Embedded Data Link (EDL) is enabled. The condition is cleared when
	the error rate falls below the synchronous data port's configured threshold value.
PORT SNMP Down	The SNMP management link is in a down state for PORT (where PORT is COM or AUX). This
	condition occurs if the PORT is configured for SNMP, and communication between the
	management system and the E1 DSU/CSU is not currently possible for this port. For the AUX port,
	this condition is detected only when a device reset or power-up occurs.
Selftest failed	A failure was detected during the power-on self-test. Select STest (in the Stat branch) to display
	more information about the failure.
DevFail ########	An internal error has been detected by the operating software. An 8-digit code appears for use by
	service personnel. The condition is cleared by resetting the device.
Download failed	A download attempt was interrupted and failed to complete. The condition is cleared by resetting
	the device.

Test in progress

A test is currently active. Select Tstat (in the Stat branch) to display more test information.
