Presentation Layer Protocol
Presentation Layer Protocol
The OSI Presentation Layer protocol is organized into a set of functional units. Each
functional unit provides a related set of Presentation Layer services. TAPS processes
implement the ISO 8322 service definitions and the ISO 8323 protocol specifications,
and provide the kernel functional unit. TAPS processes support both normal mode and
X.410 1984 mode. They do not support the context management or context restoration
functional units.
ACSE Protocol
TAPS processes provide the ACSE services. They implement version 1 of the ISO 8649
service definitions and the ISO 8650 protocol specifications. TAPS processes support
both normal mode and X.410 1984 mode. They do not support the proposed OSI
standards version 2 nor the proposed authentication addendum.

DSM/SCM, SYSGEN, and Install
For G-series releases the Distributed Systems Management/Software Configuration
Manager (DSM/SCM) configures the NonStop Kernel operating system and the Port
Access Method (PAM). PAM provides the NSP processes. For D-series releases the
system generation (SYSGEN) and Install programs initially configure the NonStop
Kernel along with the x25AM, TLAM, and TCP/IP subsystems, which provide the NSP
processes.
TACL RUN and NEWPROCESS Procedures
TAPS and TSP processes are started in one of three ways, as follows:
•
By the Subsystem Control Facility (SCF), as described in SCF on page 1-14. SCF is
the preferred method.
•
From the Tandem Advanced Command Language (TACL) command interpreter,
using a RUN command.
•
From the application, using a NEWPROCESS procedure call.
