Introduction to the Compaq FTAM Responder

The Responder and Underlying Subsystems

•

•

Compaq application, presentation, and session service provider (TAPS) processes perform the services of the Association Control Service Element (ACSE) in the Application Layer, plus the services of the Presentation Layer and the Session Layer. TAPS processes are provided by the OSI/AS subsystem.

Transport service provider (TSP) processes perform the services of the Transport Layer. These processes are provided by the OSI/TS subsystem.

•Network service provider (NSP) processes perform the services of the Network Layer and/or the Data Link Layer. These processes are provided by the X25AM and TLAM (or PAM for G06 and above releases) and TCP/IP subsystems.

The figure also shows the hardware used to implement Data Link Layer and Physical Layer OSI communications through TLAM (or PAM) or X25AM.
