Creating MTP2 Links

Applies to: Tmedia 3.0, 3.2, 3.3

Once you have created an MTP2 configuration, you must create the necessary MTP2 links. An MTP2 link is used to connect the MTP2 physical layer to a line service carrying SS7 signaling.

To create an MTP2 link:

1- Click MTP2 in the navigation panel.

Mtp2 0 A

2- Click Create New MTP2 Link in the MTP2 configuration window

Create MTP2 Link 0

3- Configure the new MTP2 link:

• Enter a name for the new link

• Select a connection mode

• Select a line service

• Assign timeslot(s) to the link

• Select a protocol type

• Select a DPC length

• Select a timeslot rate

• Select the type of Error Correction to use.

• Click Create

Create MTP2 Link 2.8 2.9

4- Verify that the "MTP2 link was successfully created" message appears

Create MTP2 Link 2
