Ntak10 Faceplate Leds - Nortel Meridian 1 Option 11C Manual

Alarm threshold recommendations for digital trunks
If a digital trunk is present in an IP Expansion cabinet, link outages due to data
network performance degradation between main cabinet and expansion
cabinet will cause alarms on the far end of the digital trunk. If link outages are
frequent, alarm thresholds on the far end may need to be increased to prevent
the trunk from being placed in a state requiring manual intervention to
recover.
