Chapter 3 - Configuring the REX2

Configuring Routing Protocol, Encapsulation and Timing

The Campus-REX2, as a default configuration, is set to bridge data. You can, however, change this setting for the Campus-REX2 to be a router. In the following procedures, you can set up the router encapsulation and timing source.

You can only configure the Campus-REX2 as a router through connection to the Console port or a Telnet session. Most router options are not configurable through the LCD menus.

1Type 1 then press ENTER to select Router as the Network Protocol.

2To change the packet encapsulation, type 2 then press ENTER . Select an Encapsulation option:

•cHDLC for Campus-REX2 to another Campus-REX2 application

•PPP when the remote Campus unit has a synchronous interface card such as a V.35 or when connecting to Ethernet equipment from another manufacturer

3To change the timing source, type 3 then press ENTER . Select a timing source setting:

•Internal (default setting) which takes its timing from an internal oscillator

•HDSL which takes its timing from the HDSL link

The Timing Source option determines the source of circuit timing on the HDSL link. The proper setting of the Timing Source option depends upon the interface card of the remote Campus unit:

•If the Campus-REX2 is connected to a Campus unit with another Campus-REX2, leave the Timing Source option set to Internal. Set the other end (remote) of the connection to HDSL; the Campus system will not operate properly if both units are set to HDSL.
