RuggedCom RuggedRouter RX1100 - Manual (Page 68)

7. Configuring Frame Relay/PPP And T1/E1
Revision 1.14.3 68 RX1000/RX1100™
Unlike PPP, a Frame Relay link can provide multiple connections. Each connection is identified by
a Data Link Connection Identifier (DLCI) and must match at the DCE and DTE. The use of multiple
connections can support meshed network interconnections and disaster recovery.
7.1.1.2. Location Of Interfaces And Labeling
Unlike the Ethernet ports (which are statically located), the location of T1/E1, DDS and ADSL ports
in your router depends upon the number of ports and how they were ordered. Refer to the labeled
hardware image as presented in the Webmin home page.
To make labeling easy to understand, all T1/E1, T3, DDS and ADSL ports are assigned a unique port
number that relates to the LEDs on the status panel.
7.1.1.3. LED Designations
The RuggedRouter includes two sources of LED indicated information about T1/E1 lines, the T1/E1
card itself and the LED Panel.
One LED is associated with each line, next to the interface jack. This LED is red when the link is
disconnected, flashes green when the link is connecting and remains solid green when the link is
established.
The RuggedRouter also indicates information about T1/E1 ports on the LED Panel. A pair of LEDs
will indicate traffic and link status of the port. Consult the section
Using The LED Status Panel to
determine which LEDs correspond to the port.
7.1.1.4. Included With T1/E1
T1/E1 includes wanpipemon, a utility that can capture traces from the T1/E1 line.
7.2. T1/E1 Configuration
Figure 7.1. T1/E1 Trunks And Interfaces
This menu allows you to display and configure T1 or E1 Trunks as well as display the routes and
status of the network interfaces.
