CCI's SMR800 Band DAS I n t e r f a ce Tra y with Independent Control provides an integrated, convenient, and single connection point when using multiple base stations with a common DAS system.  The unique architecture of the CCI DAS Interface Tray can simultaneously accommodate up to four TX/Rx inputs from single or multiple base stations.  Also provided are four extra Rx connections for Rx Only BTS ports or signal monitoring.  Independent integrated leveling controls for each pair of Tx/Rx inputs are provided in both the uplink and downlink path to achieve accommodate multiple base station inputs with different output levels in order to achieve the proper link balance to the DAS system for each base station channel.

BTS's of different technologies having different output powers can also be independently adjusted.  Base stations are connected directly to the DAS Interface Tray without the need to attenuate power as the DAS tray provides integrated high power attenuation for each channel with an adjustment range of 30 dB with 1 dB increments.  The DAS Tray is a completely passive assembly with no external power requirement thus providing the highest reliability and convenient installation. High rejection, low PIM Duplexer filters are utilized in this design.
