Description
The Circuit Identification is a logical number used to
identify the span to the MGC Manager. This number
is later used to assign the span to the network card.
Type any integer number from 0 to 65535, to be
used as the circuit identification number in the MGC
Manager.
Note: If there are other Network Services defined in
the system, the Circuit ID must be a unique
number, not used by any other Network
Service.
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.
