The parameters listed on the Reception Information page are explained in the
following table.

Parameter Explanation
Receive Status Indicates if the receive data path is operational or other status. Click
the displayed RxCode for explanation of the displayed code.
Frames Received Number of data messages received by the satellite router.
Frames with Errors Percentage of received frames determined to be corrupted. Any
number greater than zero indicates a problem except when adverse
weather conditions are present. Frames may be corrupted in adverse
weather conditions or if there is a problem with the receive cable or
antenna assembly.
Bad Key Frames Percentage of received frames that could not be decrypted
successfully. All data received over the satellite is encrypted. Any
number greater than zero indicates a problem except when adverse
weather conditions are present. Bad key frames may indicate that the
router is not commissioned.
Current Modcod Level of encoding the router can accept based on the current signal
quality. Lower Modcod numbers are used if signal impairments such as
rain are present. Adaptive coding and modulation (Modcod) is a
Hughes-developed technique that maximizes over-the-air bandwidth
utilization.
Examining receive status
You can check the Receive Status parameter to find out if the receive data path is
operational or if there is a problem. Normal receive status is indicated by the
message
Receiver operational
(
RxCode 5
).
The following two illustrations show how you can view a list of all RxCodes or see an
explanation of the currently displayed RxCode. Each RxCode—except RxCode 5
—indicates a specific problem in the receive path.
