1 INTRODUCTION
This section discusses the steps necessary to setup the Digivance CXD system communications
and operating parameters. It is assumed for the purposes of this discussion that the required
system elements have already been installed and powered on, and that the reader has an
understanding of TCP/IP networking basics.
2 NETWORKING OVERVIEW
A Digivance CXD network consists of several CPUs running the Linux operating system as
shown in Figure 3-1 Network Architecture. The CPUs residing in the Digivance CXD Hub
(called “Hub nodes”) are connected through a router to an existing LAN to effect SNMP status
and control. The CPUs in the RAN’s (called “RAN nodes”) are connected to the LAN using
WAN bridges in each SIF, which transmit packet data across a fiber back-haul from each RAN
node to its corresponding Hub. All Digivance CXD nodes support telnet, ftp, and vnc by
default.
