E3 Loopbacks
The E3 module supports the following loopbacks:
Local Card
—Loops the transmit E3output on the receive side. All cells coming
from the E3 port card are looped through the backplane and back to the E3 port
card. The transmitted data will continue to go on the output.
Network Line
—Loops the E3 received data back on the output side after the
digital data has been recovered.
Network Card
—Loops the E3 received cell payload back toward the line output.
Figure 151 illustrates the loopbacks for the E3 module.
