5–4 Rev. 1
5.1.10 The CCU Does Not Communicate with the Gateway
Possible Cause Solution
The CCU is not defined. Check that the CCU's IP address appears in the CCU list.
No network connection between the CCU
and the Gateway. Ping from the CCU to the Gateway. If no reply, refer to "The
Gateway Does Not Reply to Ping from the Control and
Management Interface."
5.1.11 The Gateway's Output is Connected to a DVB Multiplexer's
Input but the DVB Multiplexer Indicates that there is NO TS
Input.
Possible Cause Solution
The Gateway is not generating PAT/PMT
tables. Ensure that the PAT/PMT rate parameters are not set to zero.
The Gateway is not generating TS. Refer to "The Modulator Cannot Synchronize with the
Transport Stream (TS) Generated by the Gateway."
The DVB multiplexer input is disabled. Check the DVB multiplexer settings.
5.1.12 MPE Compatible Receivers Cannot Receive IP Data from the
Gateway
Possible Cause Solution
The Gateway is set to Streaming mode. Ensure that the Gateway is set to MPE mode.
The receiver does not support MPE
packed mode. Check the MPE Mode and change if necessary.
