6. Right click on the STM-1 Interface object again and select New DS-3 Interface. The DS-3 object that gets created will be the equivalent of one DS-3 worth of spans. The Interface ID will default to ID:3 indicating it is a DS3 map of spans within the optical stream. The ID starts with ID:3 because ID's 0-2 are reserved for the physical DS3 Interfaces on the rear of the IMG 2020. ID's 3-5 are reserved for DS3 over optical. Refer to the DS-3 Interface topic for more information on configuring this object.

7. Right click on the DS-3 Interface:3 object created and select New DS-3 Optical Bearer Spans. Select the Starting and Ending Offsets and the profile that will be utilized for these spans. Refer to the DS-1 Spans topic for more information on configuring the individual fields.

8. Within the DS-1 object pane is an Object Table Tab located towards the bottom of the Web GUI. Click on the Object Table tab and each of the individual DS-1's will be displayed. Click on one of the DS-1's and a Span ID:<x>pane will appear. Within this object, Loop Timing, Loopback Mode, and Logical Span Status can be configured on each individual DS-1. Refer to the DS-1 Service State Specifications topics for more information on configuring this pane.

9. Repeat steps 6-8 for and create the remaining two DS3 interfaces. They will be given ID:4 and ID:5 and will be a DS3 mapping of spans within the optical stream. Below is screen capture displaying the Optical Facility tree once all interfaces are configured.
