Table 21 Description on the fields of the display controller t3 command

Field Description

No message is sent now.

No MDL message is being sent. If an MDL message, path or idle-signal for example, was being sent, the screen would display “Message sent now: path. idle signal.”

Message data elements	MDL data elements
EIC: line, LIC: line, FIC: line, UNIT: line	EIC, LIC, FIC, and UNIT are four elements present in all
	types of MDL messages. Their values are user
	configurable and default to line.
FI: line, PORT_NO: line, GEN_NO: line	FI is found in MDL path messages, PORT_NO in MDL
	idle signal messages, and GEN_NO in MDL test signal
	messages. Their values are user configurable and
	default to line.
Periodical detection	State of periodical detection of MDL, disabled by
	default at the startup of the router.
	When the function is enabled, the screen displays:
	Periodical detection is enabled.
	No message was received.
	When MDL messages are detected, the screen
	displays:
	Message received now: path.idle signal.
	EIC: line, LIC: line, FIC: line, UNIT: line
	path/FI: line

FEAC state

No code is sent now. DS3 Line Loop Back Deactivate was last sent.

Periodical detection is enabled, no code received now.

idle Signal/PORT_NO: line

FEAC state

No FEAC signal is sent. The FEAC signal sent last time is DS3 Line Loop Back Deactivate.

Periodical detection of FEAC is enabled. This is the default applied at the startup of the router.

No FEAC signal is received now.

DS3 Line Loop Back Deactivate last	The FEAC signal received last time is DS3 Line Loop
received.	Back Deactivate.
BERT state:(stopped, not completed)	BERT state: completed, stopped (not completed), or
	running.
Test pattern: 2^7, Status: Not Sync,	Test pattern in use (such as 2^7, 2^11, 2^15, and
Sync Detected: 0	QRSS), 2^7 in this sample output; synchronization
	state, and the number of detected synchronizations
Time: 0 minute(s), Time past: 0	The duration of the BERT test and the time that has
minute(s)	elapsed
Bit errors (since test started): 0 bits	Number of bit errors received since the start of the
	BERT test
Bits received (since test started)	Number of bits received since the start of the BERT test
Bit errors (since latest sync)	Number of bit errors received since last
	synchronization
Bits received (since latest sync)	Number of bits received since last synchronization
Historical Statistics	Historical statistics
Last clearing of counters	Time when last counter clearing is performed, for
	example, 14:39:02 UTC Sat 06/25/2005. If no clearing
	is performed, “Never” is displayed.
