(3) The SEN, as previously indicated, provides wire line service for smaller size units
and CPs. The SEN consists of an AN/TTC-48 SENS (V1 or V2), a LOS AN/TRC-190 (V1)
radio assemblage, 5-kw and 10-kw generators, and support vehicles. Figure 1-20 illustrates a
typical SEN configuration and the placement and interconnection of the various equipment
items. Part A of Figure 1-20 depicts a SEN V1 configuration, which can terminate 26
subscribers. Part B depicts a V2 configuration, which can terminate 41 subscribers.
k. Mobile subscribers access the MSE network via the RAU. The planning distance for
RAU coverage is a 15-kilometer radius. Each RAU can provide support for 25 subscribers. Two
RAUs are normally deployed with each node center.
(1) One of the RAUs is collocated at the node center and is connected to the node
switch via cable.
(2) The second RAU is remoted and is connected to the node switch via a LOS
AN/TRC-190 (V1). The remoted RAU is deployed according to the subscribers' support
requirements or to fi in voids left by the node center's local RAU support.
