Custom Circuit Configuration
While Full Duplex point-to-point and Half Duplex broadcast should cover most
Out-of-Band scenarios, the Custom circuit type addresses special cases.
Although it can be used to configure typical point-to-point and broadcast
circuits, it primarily provides a means for creating atypical circuit types. Illus-
trated below is an example of how to build a full duplex point-to-point
combined with a half duplex broadcast in a single circuit.
The Custom circuit type utilizes managed devices and unmanaged/assigned
devices, rather than units. Thus, the selection process requires navigating down
to the device level to select a modulator and demodulator(s) for each channel
that will belong to this circuit.
1. Right-click on the site icon that will be utilizing the circuit and select Create
OOB Circuit from the drop-down menu to open the Circuit Creation
Wizard. The Hub site is used in this example.
The Circuit Identification dialog will appear, as shown in figure 7-23.
2. Select the Custom radio button in the Type box.
3. Enter a Label and a Description for this circuit.
