OSI/AS Architecture
The Compaq OSI/AS subsystem includes the OSI manager process along with one or 
more Compaq application, presentation, and session service provider (TAPS) processes. 
TAPS processes provide Session Layer, Presentation Layer, and ACSE services. OSI/AS 
also requires other subsystems that provide lower-layer services: the Compaq OSI/TS 
subsystem and the X25AM, NonStop TCP/IP, or TLAM ( for D-series releases) or PAM 
(for G06 and above releases) subsystem.
Note. When this manual refers to “the OSI/AS subsystem,” the meaning depends on the 
context. However, unless otherwise indicated, this term means the software and hardware 
providing all services up through Layer 7.
Note, however, that this manual covers only the use of the management facilities provided 
by the OSI manager process. Configuration and management of the lower layers also 
requires the use of management facilities provided by the underlying subsystems. These 
facilities are covered in other Compaq manuals.
