To specify the CEM functionality for an Epipe or Cpipe L2 access interface with CEM encapsulation
Note: Consider the following when creating a VLL Epipe or Cpipe L2 access interface with CEM encapsulation:
-
The Time Slots parameter of the DS0 channel must be configured with at least one time slot.
-
Time slots are automatically configured for unstructured E1 and T1 endpoints
-
The Clock Source parameter of the DS1 channel must be set to Node-Timed.
Steps
| |
|
1 |
Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.
|
2 |
Choose a VLL and click Properties. The VLL_type Service (Edit) form opens.
|
3 |
On the navigation tree, expand Site→L2 Access Interfaces, right-click on the L2 access interface and choose Properties. The VLL L2 Access Interface (Edit) form opens.
|
4 |
Click on the CEM EPipe tab or the CEM CPipe tab.
|
5 |
Configure the required general parameters.
|
6 |
For Cpipe VLL L2 access interfaces, configure the required parameters in the VLL Specifics panel.
|
7 |
For Cpipe VLL L2 access interfaces, configure the Control parameter in the Asymmetric Delay panel.
You must enable the Control parameter before you can configure the Samples parameter and the Repeat Period parameter.
You must enable the Control parameter on both ends of the Cpipe VLL to ensure symmetric delay in the jitter buffer.

8 |
Save the changes and close the forms.
