Creating the M2UA Configuration

Applies to version(s): 2.9, 2.10, 3.0, 3.2

To create your M2UA system, you must create a new M2UA configuration.

M2UA (Message Transfer Part 2 User Adaptation Layer) is used to interface the MTP2 Layer of a signaling gateway to the MTP3 Layer of a media gateway controller (MGC). M2UA can also be seen as a way to extend an MTP2 link. An M2UA link is always bound to an MTP2 link.

To create an M2UA configuration:

1- Click M2UA in the navigation panel

2- Create the M2UA configuration:

• Enter a name for the M2UA service
• Select a Node Type (SG, ASP, M2UA-MTP2 Relay)
• Click Create

3- Verify that the "M2ua Cfg was successfully created" message appears
