Input port
Minor A first-in first-out (FIFO) overflow
occurred and packet data has been lost.
This indicates one or more of the
following conditions:
Too many sessions defined from the

DNCS for the GoQAM
The data rate as defined from the

DNCS for the GoQAM session is too
low, which also means that the data
rate of the ASI input to the GoQAM is
too high
Hardware problem

Incorrect modulation mode

Major No signal. This indicates one or more of
the following conditions:
An upstream device that provides

input to the GoQAM has failed or is
offline
A cable has been disconnected

Minor MPEG continuity error counter. One or
more of the MPEG packets are being
dropped
Troubleshooting Alarm Messages
Check and Correct
Contact Cisco Services
Reduce the data rate of

input to the GoQAM
by doing the
following:
– Reducing the
amount of
incoming data
– Reducing the
amount of data
added to the
stream
– Increasing the
GoQAM
modulation mode
Verify and correct
