Switch set #1 - T1/E1 options
5, 6, 7, 8 - Loop-Back settings
The loop-back setting is used for installation and network debugging procedures. Each
of the T1/E1 ports can be individually set for loop-back mode:
• Switch 5 controls T1/E1 port 1
• Switch 6 controls T1/E1 port 2
• Switch 7 controls T1/E1 port 3
• Switch 8 controls T1/E1 port 4
When the loop-back switch for a particular T1/E1 port is enabled, the port loops the
signal from the receive port back to the transmit port. The T1/E1 loop-back test
scenarios are described in detail in under Troubleshooting, on page 24.
