Creating MTP2 Links

This article applies to: Product Version
Tmedia 2.9, 2.10, 3.0, 3.2

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.

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

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
