d. Mobile subscriber access allows subscribes to place or receive calls while moving. It
is composed of a RAU and the mobile subscriber radio telephone terminal (MSRT).
(1) RAU AN/TRC-191 is an automatic interface between mobile subscriber and the
MSE network. It allows access of the MSRT into the MSE network.
(2) MSRT AN/VRC-97 provides mobile subscribers a means of accessing the MSE
network via radio linkage.

MSE Network Architecture.
a. A MSE network may have up to 42 interlinked nodes. Typical node separation is 25
to 35 kilometers. The nodes are interconnected to form a grid network.
b. A corps MSE network can serve nearly 10,000 subscribers (8,000 static and 1,900
mobile) in a 37,000-kilometer area.
c. Node centers and extension nodes can relocate to support maneuver.
d. MSE architecture has three layers. The upper layer is the network backbone which
consists of interconnected node centers. The middle layer consists of LENs and SENs that
provide units and CPs with network access. The bottom layer consists of the system's static and
mobile subscribers.
e. Flood search allows call links to be established over any available path between two
subscribers.
3.
MSE Predeployment Planning. There are four phases in predeployment planning.
a. Predeployment phase.
(1) User requirements.
(2) Interfacing between MSE and non-MSE systems.
(3) Other system considerations are loading the preaffiliation list and publishing
trouble numbers for subscriber inquiries.
(4) Team packets used by MSE installers consist of LOS frequencies, antenna
azimuths and polarizations, site locations, activation times, profiles, and an operations order
(OPORD).
