Introduction to ATP6100
The ATP6100 subsystem consists of the ATP6100 line-handler process and a protocol
module.
The ATP6100 line-handler process, is a NonStop process pair running in a NonStop
server. The process acts as a file-system interface between an application and a
protocol module that resides and runs in the Communications Line Interface Process
(CLIP) as a task. In the wide area network (WAN) subsystem that uses the SWAN
concentrator, the ATP6100 line-handler process thus allows communication over a
variety of asynchronous communications devices (especially terminals and printers).
Application data is passed to one of several protocol modules by ATP6100.
The protocol module gives the application extensive control over the line, and each
protocol module can control either a single line or multiple lines.
ATP6100 Subsystem Management Tools
The ATP6100 subsystem supports the following utilities and tools to assist in managing
the subsystem.
•
Subsystem Control Facility (SCF)
•
Event Management Service (EMS)
•
Compaq TSM
•
HP Open System Management (OSM)
Subsystem Control Facility (SCF)
SCF is a Distributed Systems Management (DSM) interface that can be used
interactively to control, configure, and monitor the ATP6100 subsystem. The SCF
interface to the ATP6100 and wide area network (WAN) subsystems are used to
configure and manage the ATP6100 subsystem. The SCF interface to the ATP6100
