Chapter 7 – Configuring Frame Relay/PPP And T3
Introduction
This chapter familiarizes the user with:
• Configuring Frame Relay and PPP Links
• Viewing status and statistics
• Upgrading Firmware
T3 Fundamentals
A T3 is a communications circuit upon which has been imposed a digital signal 3
(DS3) signaling scheme. The scheme allows 672 “timeslots” of 64 Kbps DS0
information to be multiplexed to a 44.736 Mbps circuit.
Channel groups and fractional lines are not supported.
The RuggedRouter provides you the ability to operate Frame Relay or PPP over your
physical interfaces.
Location Of Interfaces And Labeling
Unlike the Ethernet ports (which are statically located), the location of T1/E1, T3,
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 T3
lines, the T3 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 T3 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.
