RuggedRouter® User Guide
Unlike PPP, a Frame Relay link can provide multiple (up to 990) 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.
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 T1E1, T3, DDS and ADSL ports are
assigned a unique port number that relates to the LEDs on the status panel.
LED Designations
The RuggedRouter includes two sources of LED indicated information about T1E1
lines, the T1E1 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 T1E1 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.
Included With T1E1
T1E1 includes wanpipemon, a utility that can capture traces from the T1E1 line.
