lish a connection after the framer begins seeing unframed pack-
ets. The Test Model Timing Chart below shows the amount of
time the framer must see consecutive unframed packets before
the unit will restart and try to establish a new line connection.
The reason that there are different Restart Times will become
apparent after reading the rest of the document. The 511/511E
Time Out shown refers to the amount of time the 511/511E pat-
tern will be valid. At the end of this time the pattern will automat-
ically turn itself off and the normal data path will be re-
established. The ER led will flash indicating to the user that the
test has timed out. The ER led will stop flashing once the 511/
511E switch is placed into the normal position.
