Message
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 Prt n An Out Of Frame has been detected on data port Prt n (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 Prt n The error rate of the received signal has exceeded the configured threshold for data port Prt n
(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.
DSU Operational This message only appears if there are no valid alarm or status messages.
