SS7 TCAP User Adaptation Layer (TUA)

This is the SS7 TCAP-User Adaptation Layer (TUA) component of the OpenSS7 SIGTRAN stack. This component implements the TUA functions in a STREAMS multiplexing driver.

The TUA STREAMS driver provides three interfaces: the Transaction Interface (TRI), the Transaction Component Interface (TCI) and the mOSI Transport Provider Interface (TPI).

The TUA STREAMS driver supports I_LINK and I_PLINK of Transaction Capabilities Application Part (TCI) streams providing SS7 TCAP TCAP-SAPs under the driver (SG operation). It also supports I_LINK and I_PLINK of Transport Provider Interface (TPI) streams providing Stream Control Transmission Protocol (SCTP) or other transport under the driver.

The TUA component was started in Februrary 2001.

The TUA component of the OpenSS7 stack is in the Coding stage, however, it has been rewritten on a number of occasions.

This component depends on the SS7 TCAP Transaction Capabilities Application Part Component Interface (TCI) and Transport Provider Interface (TPI) access to the Stream Control Transmission Protocol (SCTP) or other transports.

Designs for the TUA component are available here.

Documentation for the TUA component is available here. The TUA man page is available here: tua(8).
