Loopbacks
The OC3/STM-1 UNI module supports the following loopbacks:
Local Card
—Loops the transmit OC3/STM-1 output on the receive side. All cells
coming from the OC3/STM-1 port card are looped through the backplane and
back to the OC3/STM-1 port card. The transmitted data will continue to go on the
output.
Network Line
—Loops the OC3/STM-1 received data back on the output side
after the digital data has been recovered.
Figure 170 illustrates the loopbacks for OC3.
