Description
The circuit order determines the span order in which
an MCU dials out. The Circuit Order is assigned
automatically by the system according to the order in
which the spans are added.
In dial-out connections, when the operator calls the
participant, the MGC unit allocates ports from the
spans starting with the span having the lowest
number and the lowest port number within that span.
You can change the span order (if there are several
spans defined in the system) using the Set Before or
Set After buttons.
To do so:
1.Click the name of a circuit in the Circuit Order list,
which is to be adjacent to the circuit you are defining.
The circuit's entry is highlighted.
2. To insert the new circuit, do one of the following:
• Click Set Before to insert the new circuit before
the highlighted entry.
Click Set After to insert the new circuit after the
highlighted entry.
Enter the number of the DCE port that will be used by
a dial-in participant when connecting to the
conference. This number is used to identify the
participant name when a dial-in participant connects
to the conference. According to the span carrying the
call, the system identifies the Network Service and
takes the phone number from it. This phone number
is also defined in the Participant Properties dialog
box (as the CLI number). The system is therefore
able to display this participant's name in the Monitor
and Status panes.
Note: The Phone Number box is only enabled when
the Dialing Mode is set to Dial in the Settings
dialog box.
