The unit can be placed in test mode by the local user or by the remote user. The TM LED will flash for 400 msec when a valid packet is received from the Model 1001MC.

In normal Data Mode, if the box receives 4 seconds of unframed packets it will restart the box and begin trying to re-establish a connection with the far end. The distinction between framed packets and unframed packets becomes important when we discuss the Pat- tern Generator.

This symbol designates an invalid data path. If there is data present it should be ignored. 5.4 LOOPS AND PATTERNS The following section describes the Test Modes used in the Model 1088.

The remote unit will remain in the StartUP mode, NS LED on, DSL Link LED stays off, until the local unit is taken out of the Local Loop mode. After the Local Loop is deselected, the units will both be in StartUP mode and the link will be established.

So if the 511/511E is turned on during a local loop, the restart procedure is set to one minute, but the 511/511E pattern will time out after 45 seconds, allowing the framer to begin seeing framed packets (and not restart the box).
