MOOS mooring telemetry is received via PC running the SIAM portal application. The mooring initiates contact by establishing a PPP link with the portal, creating a socket and writing a message to the socket, indicating that it is available. In general, the portal implements logic to decide what, if any, operations are to be performed in the connection session Four plots used to characterize MOOS mooring telemetry are described below: portalProfile opTimeDistribution bitrateVsTransferSize packetSizeVsDeviceID
