19.1.2 SS7 M2UA – Media Gateway Controller Side

For the SS7 M2UA – Media Gateway Controller side network element, the M2UA Media

Gateway Controller link is from the IP side. MTP3 is supported in the board's software. The

MTP3 payload is sent via M3UA to the Soft-Switch. (MTP3 can also route MSUs to other

SS7 network elements via other links).

For the SS7 MTP2 Tunneling configuration, the MTP2 SS7 link payload is sent across long

distances (over the IP network). Both of its termination ends have SS7 MTP2 interfaces,

which are unaware of the MTP2 Tunneling between them.

MTP2 Tunneling is a proprietary solution, based on SS7 and SigTran standards.
