In this example a payload type of E1 is selected. This means that this line service will carry an E1 payload over the DS3 line interface.

Note: Line services employing M23 framing will always have a local index of 0.

3. The resulting line service is displayed in the information panel.

• Repeat this procedure for each line service that will be used to carry payload on the first DS3 line interface.

Note: The previous procedure for the DS3 TDM module must be carried out for each DS3 line interface, referred to as local indexes 0-2, and for each required line service carrying payload inside these DS3 line interfaces.

4. Click Create New Child Line Service to create a child line service for the DS3 line service.

• Enter a local index from 0-27 for T1/J1 lines and 0-20 for E1 lines.
