h. Affiliation. All authorized static wireline and mobile subscribes must go through a procedure called
affiliation. Affiliation is a process which allows a subscriber to gain access and be recognized as a discrete
subscriber in the MSE network. Static wireline subscribers will affiliate with a single switch in the network.
Affiliation is coordinated between a subscriber and the local switch to which it is connected. Mobile subscribers
affiliate with a local RAU. The MSRT automatically reaffiliates the mobile subscriber as it moves from one
RAU's area of coverage to another. If the mobile subscriber is engaged in a telephone conversation and leaves the
servicing RAU's range, the conversation is terminated and must be redialed.
i. In MSE, all terminal equipment is user-owned, installed, and operated. The signal officer in a FA unit
plays a critical role in assisting the MSE network managers at division (division signal battalion personnel) in
managing the network. The signal officer ensures that users are trained in operating and installing all terminal
equipment connected to the MSE network. The signal officer also ensures that the network is fulfilling customer
needs, proper coordination is made before unit CPs move, COMSEC keys and frequencies are distributed, and
subscriber problems are accurately identified. Troubleshooting is a coordinated effort between the signal officer
and MSE network manages.
PART D - SUMMARY
In this lesson, you learn the signal systems used in divisional fire support units.
a. TACFIRE is a command and control information system that processes fire missions. It is dependent on
b. The DIVARTY uses a number of single-channel radio nets to command and control operations: FM
voice, FM digital, AM voice, and AM RATT.
c. The DIVARTY also uses a wire system with established priority circuits used for the conduct of fire and
for fire support coordination and planning.
d. A FA battalion generally has eight primary radio nets (six internal and two external) to perform its
mission. In TACFIRE units, four of these nets are FM digital and four are FM voice.
e. The DIVARTY accesses the MSE network through a small extension node switch (SENS). Mobile
subscribers enter the system through their user-owned and operated mobile subscriber remote terminals (MSRT).
