1 INTRODUCTION
This section discusses the steps necessary to setup the Digivance CXD-Hub 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
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. Each Digivance CXD-Hub node supports telnet, ftp, and
vnc by default. See Section 9.4 "Accessing Nodes via TCP/IP for details.
