1 Product Overview
 0DLQ)XQFWLRQV
Antenna sharing is part of co-siting, that is, using a cabinet operating on
another standard together with a GSM cabinet in the same sector. The ASU
allows a TDMA (or other) cabinet and a GSM cabinet to share RX antennas. It
does this by sharing the RX signals between both cabinets.
The ASU is a broadband product, which means that it covers 800 –1910 MHz.

4 Function Description
The general function of the ASU is to take a portion of the RX signal and send
it to the co-sited RBS.
The ASU also switches the attenuation according to whether or not a TMA is
used. It also indicates the attenuation state via an indicator.
