2.2 FLEXWAVE PRISM HOST UNITS

The Host is designed for maximum RF flexibility to address Carriers’ changing and

evolving spectrum needs, making the most use of cost efficient resources for serving

multiple remotes such as simulcast architecture and sharing of common functions

such as power, control and management over multiple Hosts. Each Host may be

interfaced with one or more Base Transceiver Station (BTS). Each BTS provides the RF

channel inputs and outputs for a designated sector.

The Host is designed as a compact package that reduces rack space required within

a BTS Hotel. The Host is a three rack-unit high single-unit assembly that mounts in a

standard 19- or 23-inch equipment rack. Its front access interfaces with the BTS for

transport to subtended Remotes, and performs the analog to digital and electrical to

optical conversions for transport to a Host and subtended Remotes. Each Host can

support up to eight Remotes. The Remote is a modular self-contained outdoor

enclosure that houses various electronic components.

2.2.1 Host Front Panel.

The Host is designed for use within a non-condensing indoor environment such as

inside a wiring closet or controlled environment cabinet. All controls, connectors, and

indicators (except the grounding point) are mounted on the Host front panel and

allows vertical cable guides to be installed over the mounting brackets on either side.

The Host user interface on its front panel comprises the connectors, switches,

terminals, and LEDs that are described in Figure 2-3 and Table 2-1.

The Host can be mounted in either a 19- inch or 23- inch EIA or WECO equipment rack.

Unless noted other

wise, views of the Host in this document show the mounting

brackets in the 23- inch position. The defa

ult is the 19- inch position.
