7-6
Time Service Abbreviation:
This field indicates the source from which a dial-out client is
receiving Universal Coordinated Time (UTC). It is inserted in the ACTS timing message sent to
the modem client. A time service abbreviation of SPEC will appear in the timing message as
UTC (SPEC).
DUT1 Value
: This is a correction factor for converting UTC to an older form of Universal Time.
The value should always be a number between -.8 and .8 seconds. Adding DUT1 to UTC
produces UT1 (a specific measure of time related to the rotation of Earth). The three-digit string
entered in this field appears in the time messages sent to the modem client.
Leap Second:
This field allows the user to specify the addition or removal of a leap second as
well as the month and year in which this addition or removal will occur. The ACTS Server uses
this information to notify the modem client of a pending leap second. It does so through time
messages sent to the modem client.
Daylight Saving Time:
This field is used to specify the month and day of the current year in
which Daylight Saving Time (DST) is entered and exited. This information is included in the
time messages sent to the modem client.
Modem Configuration File:
The ACTS Server uses built-in, Hayes-compatible commands to
configure the modem. Some modems may support additional or different commands, which
may be required for proper configuration. If a
modem configuration file
is specified, the ACTS
Server will use the commands in that specified file to configure the modem, rather than using its
built-in Hayes-compatible commands.
Modem Speaker:
Clicking the appropriate radio button toggles the modem speaker on or off
during dial out.
The ACTS Server Greeting (Figure 7-4), accessible using the left-hand menu, is a message
sent to a modem client when a connection is made. The Acts Server Greeting screen allows
the user to customize the greeting message for the specific application.
