TCP-IP Interfaces
All data (TM, TC, Ranging, Monitoring & Control, Logging, etc…) are exchanged between the Signal Processing
Software and the external world (Monitoring & Control Software, COP Software, Control Center clients, etc…)
over a single Ethernet port. The CORTEX CRT Quantum acts as a TCP-IP server for all types of data transfer.
Data are exchanged using the connected-sockets communication protocol.
Some data flows accept multiple clients at a time (monitoring, logging, telemetry, Doppler and spectrum analysis
data), while other flows accept only one client at a time (equipment configuration and reset, satellite
telecommanding).
Each type of transfer flow is allocated a specific port number which the clients use for connecting themselves to
each « service ». Port numbers are listed below (including TCP-IP ports on the optional COP Software package):

: “Vector Analysis Data” port available only for SPS 5.30 and higher
A detailed description of this interface (excluding COP ports) is available in Annex 1. The COP software Ethernet
interface is described in RD6.
