AbstractIRIG 106-17 defines interoperable two-way network telemetry interfaces for the wired as well as the dynamic TDMA air interface. While the air interface is based on the familiar SOQPSK-TG waveform, a TmNS-based radio contains a dynamic TDMA MAC regulated by Link Management through the use of RFNMs. This paper illustrates the TmNS-based radio aspects of the IRIG standard by describing our experience utilizing a two-track approach for accelerated TmNS compliant radio development. We have divided the architecture by engineering discipline lines (Communications vs. Computer Engineering). Doing so allowed us to accelerate the design, simulation, and test tasks while using a common code base across various transceiver implementations. Discussion includes a description of the software modules that provide TmNS interfaces for standards compliant radio functionality such as the TDMA MAC, RFNM processing, system management, and MDL configuration as well as system-level integration testing.
