Installation -- Continued	Installation -- Continued
Switch set #1 - T1/E1 options	Switch set #2 - serial and ethernet 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.

1, 2, 3 - Serial connection speed line settings

Switches 1, 2, and 3 on switch set #2 are used to set the serial connection speed.
