Configuring TDR on TX Access Card
The Time Domain Reflectometer (TDR) sends a signal from one end of a cable and measures the time
for the signal to reflect back. To detect shorts and breaks, to measure the length of the cable, and to find
other physical-layer network problems, use the TDR.
The TDR is used for Fast Ethernet ports on 10/100BASE-TX and 4-Port Gigabit Ethernet 8-Port 10/100
Ethernet TX access cards. For information about how to use the TDR, refer to "Testing for a Cable
Problem on a Fast Ethernet Interface" in the
Internet Router
