Chapter II Communications Planning Cycle 1. Assess Force Structure Requirements a. What is the mission requirement? Who, what, where, when, why (OPLAN/EXPLAN/EMOP)? b. Validate mission requirements against established SDB (per OPLANS/EXPLANS/EMOP/fragmentary order/Annex-K), and CJCSI 6250.01A priority code. 2. Acquire Resources Figure II-1. Communications Planning Cycle a. Define unit specific resources. TACSAT resources are extremely constrained due to proliferation of TACSAT capable radio systems. Based on system constraints a unit may receive an assignment that provides for lower data rates than originally requested. Communications planners validate all resource requirements based on mission criteria and ensure that realistic resource requests are submitted based on mission analysis. (1) Do not use TACSAT networks for routine traffic when other systems and modes of communication are available. (2) Do not request resources at a higher priority than required. II-1
. Voice. (1) Bandwidth (25-kHz or 5-kHz). (2) Mode (DAMA or dedicated). (3) Data rate (2.4-kbps or 16-kbps). (4) Criteria. (a) Per the JCS, narrowband voice mandate, compatibility with advanced narrowband digital voice terminal (ANDVT) application 3 using voice digitization at 2.4kbps is the joint standard for secure voice operations via UHF satellites. (b) For a number of high priority networks, the COCOM can designate that a network operate at 16-kbps for technical or voice recognition requirements. c. Data. (1) Bandwidth (25-kHz or 5-kHz). (2) Mode (DAMA or dedicated). (3) Data Rate (75-bps to 64-kbps). (a) The major factors that determine data rate selection are the file size required to be transmitted, the volume of traffic, and tolerance for delay in access to the circuit. (b) Larger file sizes require greater throughput speed (for example, a file size of 50-bytes may be transmitted over a 300-baud link, but a 1.2-megabyte file may require a nine.6-kbps link). d. Duty cycle. (For what percentage of a 24-hour day is access to the circuit required?) (1) Low—1 to 2 hours access per 24-hour period. (2) Medium—2 to 8 hours access per 24-hour period. (3) High—8 hours or more access per 24-hour period. e. Access period. Coordinated universal time date-time group of start access date and stop access date with specific periods of use per day (for example, 0700Z to 1700z daily). Request 24-hour access if mission analysis identifies the requirement. f. Traffic priority. CJCSI 6250.01A identifies a prioritization scheme to determine access to both the core warfighting and enterprise-wide SATCOM resource apportionment. See Appendix J for the prioritization scheme used to determine access. g. Mission rationale (for specific/special resource request). (1) Equipment, platforms, or mission capabilities/limitations (such as not capable of operating in all modes or bandwidths). (2) Support relationships (special users, coalition users). (3) Geographic or physical location (DAMA MHOP), footprint, look angle constraints. II-2
