The M2UA (Message Transfer Part 2 User Adaptation Layer) is used to interface MTP2 of the signaling gateway to the MTP3 of a media gateway controller. M2UA can also be seen as way to extend a MTP2 link. An M2UA link is always bound to an MTP2 link.
Here is a diagram of a setup using M2UA:
As you can see the M2UA layer can interface with either a NIF or MTP3 layer. Therefore M2UA has 2 modes of operation. Toolpack can configure M2UA in both modes.
TelcoBridges and M2UA
TelcoBridges supports M2UA as part of its SIGTRAN implementation. Additional information will be provided when SIGTRAN ships at the end of 2009.
