Install Chassis

There are three types of BTS chassis: Combo, Split and TTA (Figure 23). Prior to Ripwave

Release 1.19 (2.4 GHz systems), only the Combo Chassis was used, but with the licensed bands

(2.3, 2.5, and 2.6 GHz systems) it is allowed to transmit at higher levels of power, which

required better air circulation. This resulted in the introduction of the Split Chassis.

The recently introduced Tower Top Antenna (TTA) chassis, consists only of a digital shelf

because the PAs are incorporated into the base of the RFS. Notice that the TTA digital shelf

includes 8 new additional cards called RF Controllers or RFC.

CAUTION! - Please contact Navini Technical support before attempting to

exchange cards between chassis of different type and frequency to verify

compatibility.
