(1) Secure automatic voice/data communications and internal communications security
(2) Discrete addressability.
(3) Automatic reaffiliation during movement.
(5) A 15-kilometer (9.3-mile) range.
f. The MSRT allows the user to dial up and communicate with any discretely-addressed MSE
subscriber. The mobile subscriber accesses the network via the radio access unit (RAU) deployed and
operated by the signal battalion. RAUs are located in the vicinity of the node centers and throughout the
division area of operations to provide battlefield coverage. A RAU can provide a 15-kilometer radius
area coverage (planning range) in the area of operations. Figure 2-15, page 2-16, illustrates how mobile
subscribers access the MSE network. The depicted MSE network uses four node centers (NC). RAUs,
located at various locations throughout the network, provide access to mobile subscribers.
g. Affiliation. All authorized static wire line and mobile subscribers 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 wire line 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.
h. In MSE, all terminal equipment is user-owned, installed, and operated. The signal officer in
an air defense battalion plays a critical role in assisting the MSE network managers at division
(personnel from the division signal battalion) in managing the network.
i. The signal officer must ensure that:
(1) Users are trained in operating and installing all terminal equipment connected to the MSE
(2) The network is fulfilling customer needs.
