1 INTRODUCTION
This section describes the basic components of the Digivance CXD system including the Hub
and Remote Access Node (RAN) equipment. The Hub equipment consists of the Central
Processing Unit (CPU), the System Interface (STF), the Sonet Interface (SIF), the Full Band
Hub Down Converter (FBHDC), the Hub Up Converter (HUC), the Forward Simulcast Card
(FSC) and the Reverse Simulcast Card (RSC).
The RAN is an assembly that consists of the RAN equipment including the RAN Chassis,
CPU, STF, RAN Down Converter (RDC), RAN Up Converter (RUC), and RF Assembly
(RFA).
1.1 Digital Chassis
The Digital Chassis, shown in Figure 2-1, is a rack-mounted chassis (known as the digital
shelf) capable of housing 8 industry standard cPCI circuit card modules; one CPU module, one
System Interface module (STF), and Six RSC/SIF digital modules.
