Protocol Tabs
LED Quick Status Area
SONET - LED Quick Status Area
The left side of the screen provides an at-a-glance view of the current protocol
processor's LEDs and Laser ON/Off button. The LEDs report incoming error and alarm
activity, current status, and event history to help narrow the focus if problems are
detected on the incoming signal and provide a starting point when trying to diagnose
problems.
This portion of the screen allows you to quickly scan and target potential problem areas.
The LED Quick Status Area contains the following areas:
•
Laser On/Off button: Enables you to turn the laser on and off. (only for optical
interfaces)
•
TX: Displays the transmit interface configuration, such as rate, wavelength,
framing, and/or duplex depending on the specific protocol processor
If a non-SONET interface is selected from one of the other protocol tabs, then
"Not Assigned" will be displayed.
If a laser module is not inserted then "No Laser" will be displayed.
•
RX: Displays the received optical power in dBm. This status indicator will flash
when one or more received Optical Lanes' power level exceeds the laser
module's Power Warm or Power Hot thresholds.
For MPM cards that have an MLD tab this is an aggregate broadband power
value, based on the combined power levels from all of the laser module's received
Optical Lanes. See the
power levels.
•
E/A: Indicates the current
SONET signal. This is a status indicator.
•
Test Paused: This LED will turn Red if the
Any errors or alarms received while the test is paused will not be recorded in any
of the Results statistics.
•
CLK: Indicates the value of the Transmit Clock Reference function. This is a
status indicator.
•
CLK:INT displays when configured for Internal clocking.
