Function 142: Automatic time setting
1: Synchronize with Caller ID
This function, when enabled, synchronizes the real-time clock with Caller ID (CID) messaging: call
processing compares the time of a CID message to the system real-time clock and, if the difference is
more than two minutes, resets the real-time clock to match the time (minutes) of the CID message. The
system will analyze each such message (or — if it receives more than four calls with CID information
within a one-minute period — as is needed). Select ENABLE or DISABLE by pressing a scroll key (either
or
). Choosing ENABLE will allow the CID data to update the time and date.
Default: Disabled.
Esi-Link-related notes (see also "Function 83: Esi-Link programming," pages M.9–M.10):
If "synchronize with Caller ID" is enabled, Esi-Link time synchronization (from location 700)
will be disabled.
If "synchronize with Caller ID" is disabled, Esi-Link time synchronization will be allowed (minutes only).
When Esi-Link is used, all cabinets' time will be synchronized by cabinet 700, unless "synchronize
with Caller ID" is enabled in Function 142.
2: Adjust for Daylight Saving Time
This function, when enabled, causes the real-time clock to adjust itself automatically for Daylight Saving
Time (DST). Select AUTO or DISABLE for DST by pressing a scroll key (either
DISABLE is best for those areas that don't observe DST.
Default: Disabled.
Note: If this function is enabled and it causes an automatic time change, the system won't update the real-
time clock from either Caller ID messages (Function 1421, above) or Esi-Link time synchronization
for 25 hours before and 25 hours after the time change is due to be effective (i.e., 2:00
Function 143: Clock adjustment
This function lets the Installer or Administrator have the system automatically compensate for a clock that's
running too fast or too slow. The clock adjustment speeds up or slows down the clock over a 30-day period by
the amount selected. If the system clock is running slow, select a positive value. If the clock is running fast,
select a negative value.
Range: -2 to +5.5 minutes. Default: 0.
Example: If the clock is running two minutes fast over a month, select -2 (minus two minutes).
