E XAMPLE N ETWORKS
We provide several example networks, beginning with a simple network and progressing to more
complex networks. You may find the configuration instructions provided for each example helpful
when configuring your own network.
We include the following chapters:
• Simple Remote Bridging Network
An example of a simple network using remote bridge devices toaccessa CyberSWITCH’sfour
basic rate lines.
• Remote Bridging Network with Security
A bridged network with Calling Line Id security and Bridge MAC Address security enabled.
The network is configured with two devices. One device will be configured to require a Bridge
MAC Address security password, and one device will not. This network uses BRI lines.
•IPRoutingNetwork
An IP routing network with devices accessing the network from their homes.
• IP Routing Network with Remote Bridge Devices
A smart bridging interface to allow the two remote bridge devices to connect to an IP subnet.
The CyberSWITCH treats these devices connected to the Smart Bridging network interface as
if they were connected to the same Ethernet segment.
• IP Routing Network with PPP Devices
Uses IP routing to connect two of our products, both using PPP. Each system is on a separate
LAN. The configuration for this network is designed to allow three different types of accesses.
•IPXRoutingNetwork
A sample networkusing IPX protocol to communicate with remote bridges as well as a remote
IPX router.
• AppleTalk Network
An AppleTalk network made up of two LANs, separated by the WAN.

OVERVIEW
This chapter provides an example of a simple network using remote bridge devices to access four
basic rate lines in the CyberSWITCH. Bridges are formed between each of the LANs to which the
remote bridge devices are connected, and the LAN to which the CyberSWITCH is connected.
The following section provides the initial installation steps that would be used with any type of
network installation.
INITIAL INSTALLATION STEPS
The initial steps in the CyberSWITCH installation process are basically the same no matter how
complicated the network. These steps are:
• completing the requirement worksheets
•orderingISDNservice
• powering on the system
• accessing Release Notes
• connecting an administration console
• setting up Telnet access
• upgrading system software
• changing defaults to secure system
• returning configuration to factory defaults
The chapters Accessing the CyberSWITCH and Upgrading System Software (in the User’s Guide)
describe each of these steps in detail.
Worksheets for this network are included on the next few pages.
CONFIGURING THE SIMPLE REMOTE BRIDGE
Because this is a simple bridged network, you only need to fill out the System Details and Bridging
and Routing Information worksheets. The worksheets for Example 1 are on the following pages.
