Clarinet: Data
Communication Test Equipment
|
|
- The Clarinet-system, developed by
Acacia, is a very powerful PC-based tool for testing protocols
on ATM, LAN, and WAN networks.
- The hardware units - Clarinet-Books -
can be connected to any PC-Desktop or Notebook running Windows®
98 or Windows® 2000.
|
|
- ATM
- ISDN-BRI
- ISDN-PRI
- Trunk E1 / T1.
- Ethernet AUI, 10base2, 10baseT.
- V24-V28, V35, V36 and X24-V11
interfaces.
|
|
- Protocol decoding according to a
user-specified protocol stack.
- Statistics: message counting , flow
details.
- Filtering and triggering on message
type.
- Simultaneous network/user simulation and analysis (ATM,
ISDN, QSIG, SS7, V5, IP, Frame Relay, X25,).
- Clarinet-API: development of programs
in the C language.
- Conformance testing: execution of ETS,
compilation of ATS.
- User-friendly operator interface using
dialogues under MS-Windows.
- Easy use of multiple interfaces by connecting units to the
USB or SCSI2 bus.
|
|
- Common protocols supported on bit or
character oriented links in a user-specified stack
- ATM cells,
HDLC frame, Asynchronous characters, ATM UNI & PNNI, ISDN,
QSIG, V5, X25, Frame Relay, IP/IPX, H323, TCP,
X224/X225, V120, PPP, LCP, GSM, SS7 and many variations
(national versions, RFC extensions, ISO/ITU/ANSI...)
|
Clarinet: A Protocol Analyzer
|
|
- All the exchanges occurring on the
Interface Under Test are time-stamped with resolution of 0.1
millisecond (0,1 microsecond ATM).
- The events are recorded in real-time
directly to hard-disk in their native format (binary data +
date).
- The events report the physical state (ATM, E1/T1, BRI, Vseries), bop framing, Bert counting....
- The beginning and end of recording can
be triggered on any user specified events.
|
|
- An event editor displays the events
stored on hard-disk :
- Events are decoded and translated
under protocol strings.
- The protocol stack specification
provides an unlimited number of combinations for two
channels.
- The editor can select the events in
the file according to filter specification.
- Powerful search and edit facilities
allow easy location and manipulation of desired events.
|
|
- A complementary function provides
statistics counting on BOP events, data flow, delay events.
- Counters can be displayed under
history or counter modes.
|
|
Protocols
|
- Automatic simulator allows controlled ATM UNI, ISDN, QSIG,
ISUP, communications, X25 or Frame Relay circuits.
- The built-in simulator emulates the layers of protocol and includes the
behavior functions:
- Generator (outgoing call)
- Responder (incoming call) .
|
Control and
Parameters
|
- The messages and parameters are fully
specified within the Windows dialogue. The parameters allow
configuration of:
- Network/Terminal mode,
- Versions of protocol (ATM, ISDN, SS7, SVC/PVC)
- Time-limits values...
- Commands allow the user to manually
control the simulator: call/clear, send messages,
- Built-in data sources are available to
fill in channels or virtual circuits
|
|
C Language
|
- The Clarinet-API provides all the
interfaces for programming in the C language.
- The executable program specifications
are included in the standard Clarinet environment.
|
|
TTCN
|
- The Conformance Testing Simulation
runs executable programs generated by using the
Clarinet-TTCN-compiler and the API interfaces.
- Software packages corresponding to
standard ETS are available (ATM, ISDN, QSIG, SS7, V5, Frame Relay X25).
- Optional functions are dedicated to
conformance testing:
- Setting of parameters
(PICS/PIXIT;TC list)
- Full TTCN-GR trace
- Access to HTML TTCN edition
|
|
User
Interface
|
- The Clarinet-manager offers a
user-friendly operator interface developed under the Windows
environment
- The choices of configuration are
selected by a Windows dialogue and systematically saved in
files.
- Configuration of tests are defined in
Clarinet profiles. Profiles can be automatically repeated,
chained, looped...
|
Versatility
|
- Clarinet-Book units can be supported
by any type of PC: Desktop or Notebook.
- USB or SCSI2 ports are used for
multi-point connection.
- Different types of Clarinet-books
can be mixed on the USB bus or used independently.
- The software can be installed under Windows 98 or Windows
2000 .
|
|
|
- CLARINET-System has many functions to
evaluate the behavior and performance of PBX, terminals,
switches supporting ATM, WAN and LAN protocols. Versatile
configurations of the automatic simulator, programmable
simulation and protocol-stack analysis can be combined.
|
|
- CLARINET-System provides a reference
against which to validate communications equipment in a
production line. The automatic simulator and the analyzer run
pre-prepared profiles.
|
|
- CLARINET-System, with the complementary
ETS packages, is a powerful and low cost TESTER to run standard
ETS or to compile ATS developed in TTCN language.
|
|
- CLARINET-System is a powerful tool to
investigate when random faults occur on links and networks:
the triggers and recording capabilities allow all of the
messages and physical states to be stored.
