Data Analyzer Overview
The data analyzer is supplied with the ACC Base System product. It is a
software based tool that allows real-time capture and analysis of X.25
traffic on one or more X.25 links simultaneously. It runs within an
HP-UX based HP 9000 system. Although the data analyzer is designed to
monitor X.25 or ISDN traffic from the ACC products, it can be attached
to any RS-232 or V.35 X.25 connections with line speeds up to 1222 Kb/s.
Each X.25 connection to be monitored on an 8-Channel card requires two
ACC multiplexer ports, thus a single 8-channel ACC multiplexer card
can support up to four analyzer sessions. Two ports are required on the
8-channel PCI card only if a non-ACC X.25 link is being monitored. The
analyzer can provide up to 8 concurrent sessions by using the ports on
two or more 8-Channel ACC cards. For ISDN traffic analysis, each
connection requires only one sub-channel.
The Data Analyzer is composed of three major components:
• HDLC frame receiver multiplexer firmware
• HP-UX capture/filter daemon
• Display and analysis program
Figure 1-1 on page 13 shows the relationships between these
components, as well as the unique 'software-only' input configuration
with respect to the 8-Channel PCI ACC products. Configuration
information is set up either in the ACC TTGEN configuration file, or
dynamically by means of the convenient runc command.
