6100 MPS-B Programming Manual

SECTION 1
INTRODUCTION TO 6100 MPS-B
The 6100 Multipoint Supervisor-Burroughs (MPS-B) protocol allows
an application process, executing in a Tandem system, to act as
the supervisor station controlling tributary stations on a
multipoint asynchronous or byte synchronous line.
6100 MPS-B provides a protocol that conforms to the ANSI Standard
X3.28, "Data Communication and Link Specification" Subcategory
2.5 (Establishment and Termination Procedure: Two-Way Alternate,
Nonswitched, Multipoint with Centralized Operation and Fast
Select), and Subcategory A4 (Message Transfer: Message-Oriented,
with Replies and with LRC--Longitudinal Checking).
Specifically, 6100 MPS-B supports the following types of
tributary stations:
• Burroughs terminals using the Burroughs Basic Poll/Select
protocol.
• Lear-Siegler ADM-2 Data Display terminals with polling option.
• NCR terminals using NCR Multipoint protocol.
An application process communicates with the 6100 MPS-B protocol
module through the CP6100 I/O Process.
The 6100 MPS-B protocol module provides functions similar to
those described for the ENVOY ADM-2 Multipoint Supervisor in the
ENVOY Byte-Oriented Protocols Reference Manual.
This book describes the 6100 MPS-B protocol module. It provides
information you need to set up an MPS-B configuration and write
programs that supervise an MPS-B environment. These sections
assume that you know the protocol supported by MPS-B and that you
have read the CP6100 I/O Process Programming Manual.
