Front panel and Ethernet port LEDs
This article explains how to interpret the front panel and Ethernet port status LEDs on both the Dialogic® 1000 Media Gateway Series (DMG1000) and the Dialogic® 2000 Media Gateway Series (DMG2000).
Front panel indicator:
Green LED Off: No link.
Green LED On: Link is active.
Green LED Flashing: Link is active and there is traffic on the link. The flash rate is determined by the amount of network traffic: more traffic implies a higher traffic rate.
Indicators on the Ethernet connector:
Green LED Off: No link.
Green LED On: Link is active.
Green LED Flashing: Link is active and there is traffic on the link. The flash rate is determined by the amount of network traffic: more traffic implies a higher rate.
Yellow/Orange LED Off: Link is inactive (if green LED is also off) or (if green LED is on) link is operating in Half-duplex mode and no collisions are occurring.
Yellow/Orange LED On: Link is operating in Full-duplex mode.
Yellow/Orange LED Flashing: Link is operating in Half-duplex mode and one or more collisions have occurred. Flash rate is determined by the collision rate: a higher flash rate implies a higher collision rate.
What to look for in case of issues with degraded voice quality:
The key indicator to look for is the yellow/orange LED on the DMG 1000 or DMG 2000 Ethernet port.
If the yellow/orange LED indicates that the port is operating in Full-duplex when the Ethernet switch to which the port is connected is configured for Half-duplex (or vice-versa), then excessive collisions or errors may be caused which may result in degraded voice quality.
