7 Connection Once the TB8100 BSS hardware is installed, you need to connect the individual modules to each other, and to any ancillary equipment required in your system. This chapter provides information on all the inputs and outputs available on the TB8100 BSS. 7.1 Overview of Inputs and Outputs This section identifies the main input and output connections for the TB8100 BSS. Figure 7.1 below identifies the connections at the front of a dual base station, and Figure 7.

We recommend that a standard 3-wire grounded outlet is used to supply the AC power. The socket-outlet must be installed near the equipment and must be easily accessible.
Terminate and insulate the DC input leads so they are protected from accidentally shorting to the subrack if the PMU is removed before the leads are disconnected.

The RF output is via the N-type connector on the rear panel of the PA (refer to Figure 7.3 on page 85). We recommend that you use dual-screened coaxial cable such as RG223 for the BNC connections, and RG214 for the N-type connections.
7.4 System Connections The reciter can be fitted with an optional system interface PCB which provides the links between the reciter’s internal circuitry and external equipment. This PCB is securely mounted to the reciter’s chassis and is connected to the control PCB with a flexible connector. The system interface PCB is fitted with industry-standard connectors and several standard types are available for different applications.
