5.0 OPERATION

Once the Model 1088 is properly configured and installed, it should oper- ate transparently. This sections describes power-up, reading the LED status monitors, and using the built-in loopback test modes.

5.1 POWER-UP

To apply power to the Model 1088, first be sure that you have read sec- tion 4.3, “Connect Twisted-Pair DSL Interface” on page 16, and that the unit is connected to the appropriate power source.

5.2 LED STATUS MONITORS

The Model 1088 features six front panel LEDs that monitor power, the DTE signals, network connection and test modes. Figure 10 shows the front panel location of each LED. Following Figure 10 is a description of each LEDs function. See also APPENDIX E.

	Figure 10. Model 1088/K Front Panel
DSL LInk	(Active Green) Solid green (On) indicates that the
	end to end DSL Framer Link is up, signifying that
	the link across the DSL span is active. The DSL
	Link LED is Off when the link is down.
E1/FE1	(Active Green) Solid green (On) indicates a valid
Link	E1 connection.
LOS	(Active Red) The Loss of Sync indicates that the
	unit has lost synchronization with the incoming sig-
	nal. This may happen when there is a framing mis-
	match or a loss of signal. In unframed mode, the
	LOS LED monitors the status of the transmit clock.
NS	(Active Red) The No Signal LED glows red to indi-
	cate that the local Model 1088 is not connected
	with the remote Model 1088.
