Search Pattern 1 (SP1) reduces the time re-
quired for link setup so that the user can
start talking sooner or data transmission
can begin sooner. SP1 should be selected
if synchronization within the SECOM-H net
is good, i.e. if the last time acquisition took
place not too long ago.
Late Traffic Entry (LTE) is only supported up to
Search Pattern 3.
The greater the search pattern, i.e. the tolera-
ble deviation, the longer the time required for
link setup.
