9.1.7.1.2 Clear Channel<br />

553<br />

Section 9<br />

Radio Communications family<br />

This section specifies the 8-bit enumeration <strong>for</strong> the Clear Channel field in the CCTT SINCGARS<br />

Modulation Parameters.<br />

Field Value Enumeration<br />

0 Not clear channel<br />

1 Clear channel<br />

9.1.7.2 JTIDS/MIDS Modulation Parameters<br />

Detailed in<strong>for</strong>mation about the JTIDS/MIDS (Radio System Type 8) shall be communicated by using<br />

the Modulation Parameters in the Transmitter PDU. The Modulation Parameters shall contain the<br />

following fields:<br />

1. Time Slot Allocation Mode - Defines the fidelity level to be used (range 0 to 4)<br />

2. Transmitting Terminal Primary Mode - Defines the primary mode of operation of the<br />

transmitting terminal. See section 9.1.7.2.1 <strong>for</strong> details<br />

3. Transmitting Terminal Secondary Mode - Defines the secondary mode of operation of<br />

the transmitting terminal. See section 9.1.7.2.2 <strong>for</strong> details<br />

4. Synchronization State - Defines the current synchronization state of the transmitting<br />

terminal<br />

5. Network Synchronization ID - For TSA modes 0-2, it shall be set to default. For TSA<br />

modes 3-4, it shall be a 32-bit r<strong>and</strong>om integer generated by using the DIS timestamp as<br />

the seed. Only an NTR can generate a Network Synchronization ID; all other<br />

participants shall use the ID obtained from the NTR to which they are synchronized<br />
