IMEOUTS
The restart procedure is in place to allow the units to re-establish a connection
after the framer begins seeing unframed packets. Table 6-2 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 timeout shown refers to the amount of time the 511/511E pattern will
be valid. At the end of this time, the pattern will automatically turn itself off and
the normal data path will be re-established. The ER LED will flash, indicating that
the test has timed out. The ER LED will stop flashing once the 511/511E switch is
placed into the normal position.
