SS7 MTP Level 2 User Adaptation Layer (M2UA)

This is the SS7 MTP2-User Adatapation Layer (M2UA) component of the OpenSS7 SIGTRAN stack. This component implements the M2UA functions in a STREAMS multiplexing driver.

The M2UA STREAMS driver provides the Signalling Link Interface (SLI).

The M2UA STREAMS driver supports I_LINK and I_PLINK of Signalling Link Interface (SLI) streams providing SS7 MTP Level 2 signalling links under the driver. It also supports I_LINK and I_PLINK of Transport Provider Interface (TPI) streams providing Stream Control Transmission Protocol (SCTP) or other transports under the driver.

The M2UA component was started in January 2000.

The M2UA component of the OpenSS7 stack is in the Testing stage, however, it has been rewritten several times.

This component depends on the SS7 MTP Level 2 Signalling Link Interface (SLI) and Transport Provider Interface (TPI) access to the Stream Control Transmission Protocol (SCTP) or other transports.

Designs for the M2UA component are available here.

Documentation for the M2UA component is available here.

OpenSS7 has participated in testing events for the M2UA component. These are:

ETSI SIGTRAN Plug Test

Test results have not yet been released to the public.

Code is not yet publicly available.

The SS7 MTP2-User Adaptation Layer (M2UA) is an integral part of the OpenSS7 STREAMS SIGTRAN stack and can be found in the m2ua sub-directory in the strss7 release code. Please see the Downloads Page and CVS Archive Page for more information.
