4. ANALYSIS PARAMETERS
The menus described in this section are used to set parameters which the AM8a uses for
interpreting expected events as well as analyzing the events that occur during a call sequence.
The parameters provide lower and upper ranges or single-value thresholds for event
recognition and for flagging failures of specific events. To use these menus, the operator
must first select the
ANALYZE
Setup menu. The parameters are then set as menus are
displayed.
During tests, if an event falls outside of the programmed range, the display will indicate this
failure by flashing the analysis line of the Events Display; when the ">"character is selected
for analysis, the detail line will flash to indicate that an Event in the call sequence failed.
The user may then move the cursor to find the specific Event which failed. Once the failed
Event has been selected, the specific detail which failed will flash. An
RS232
report will flag
an out-of-spec. event with an "*".
4.1 HOOK ANALYZE
This menu controls how the AM8a interprets "
ON HOOK
" conditions. This applies to all
TRUNK TYPES
that can be selected in the
CONFIG SETUP
menu. See 4.11.2 for
OFF HOOK
information if
ANALOG
(loop) is used.
HOOK :
ANALYZE: FLASHms(min)
450
50 to 1250 (1ms steps)
DISCONNECTms(min)
1000
50 to 1250 (1ms steps)
Alternate:
4.1.1
FLASHms(min):
An "
ON HOOK
" greater than the
FLASH
timing but less than the
DISCONNECT
time is considered a hook flash.
An "
ON HOOK
" duration less than the
FLASH
time is considered to be a dial pulse digit.
4.1.2
DISCONNECTms(min):
If the duration of an "
ON HOOK
" signal exceeds this parameter,
the AM8a assumes a true disconnect has occurred and will interpret the next "
OFF
HOOK
" as the beginning of a new call..
