8. Configuring Frame Relay/PPP And T3/E3
Revision 1.14.3 81 RX1000/RX1100™
Figure 8.3. T3/E3 Network Interface With Logical Interfaces
8.2.1.1. Naming Of Logical Interfaces
RuggedRouter names the logical interfaces that are created for T3/E3 Trunks, but allows you to
provide a description. All interfaces start with a "w" to identify them as wan interfaces, followed by the
interface number. The next part of the identifier is either "ppp" or "fr" and the frame relay DLCI number.
8.2.1.2. T3 Interface Parameters
The Edit T3-X Parameters link from the T3/E3 WAN Interfaces menu links to this menu, which
displays and configures T3 Trunk parameters, including the option to use the interface in E3 mode.
Figure 8.4. Edit T3 Interface
The Framing field determines the framing format used. Your line provider will indicate the correct
format.
The Line Decoding field reflects the line encoding/decoding scheme. Almost all T3s now use B3ZS.
The Clocking field selects whether to accept or provide clock signal. In normal use the central office
provides the clock signal in which case the setting should be "Normal". It is also possible to connect
to another router, for example, by using a cross-over cable and selecting "Master" on one of the two
routers to provide the clock signal.
The link: Convert this interface to E3 reconfigures the interface for use as an E3 trunk.
