FAM Loopbacks
The FAM module supports the following loopbacks:
Local Card
—Loops the transmit FAM output on the receive side. All cells coming
from the FAM port card are looped through the backplane and back to the FAM
port card. The transmitted data will continue to go on the output towards the
trunk card.
Network Line
—Loops the DS1 received data back on the output side after the
digital data has been recovered.
Network Card
—Loops the DS1 received payload back toward the line output.
Figure 154 illustrates the FAM loopback options.
