9.1.4 Crypto System<br />

551<br />

Section 9<br />

Radio Communications family<br />

This section specifies the 16-bit enumeration <strong>for</strong> the Crypto-System field in the Transmitter PDU.<br />

Field Value Radio Crypto System<br />

0 Other<br />

1 KY-28<br />

2 KY-58<br />

3 Narrow Spectrum Secure Voice (NSVE)<br />

4 Wide Spectrum Secure Voice (WSVE)<br />

5 SINCGARS ICOM<br />

9.1.5 Antenna Pattern Type<br />

This section specifies the 16-bit enumeration <strong>for</strong> the Antenna Pattern Type field in the Transmitter<br />

PDU.<br />

Field Value Antenna Pattern Type<br />

0 Omni-directional<br />

1 Beam<br />

2 Spherical harmonic<br />

9.1.6 Reference System<br />

This section specifies the 8-bit enumeration <strong>for</strong> the Reference System field in the Beam Antenna<br />

Pattern record <strong>and</strong> the Spherical Harmonic Pattern Record in the Transmitter PDU. The<br />

enumeration <strong>for</strong> the Reference System are limited to the two listed below.<br />

Field Value Reference System<br />

1 World Coordinates<br />

2 Entity Coordinates<br />

9.1.7 Modulation Parameters, used in the Transmitter PDU<br />

This section specifies the Modulation Parameters in the Transmitter PDU.<br />

9.1.7.1 CCTT SINCGARS Modulation Parameters<br />

Detailed in<strong>for</strong>mation about the CCTT SINCGARS (Radio System Type 6) shall be communicated by<br />

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

contain the following fields:<br />

1. FH Data - These fields are only used when the SINCGARS radio is in FH mode. They<br />

determine the hopping pattern of the SINCGARS radio. If any one of these fields is<br />

different, except FH Synchronization Time Offset, the hopping pattern is different.<br />

Radios on different hopping patterns shall not communicate.<br />

a) FH Net ID - This field shall identify the frequency hopping network.
