Newsletter: GL Announces Enhanced T1 E1 Products and Software Version 6.22

Welcome to an October 2012 issue of GL's Newsletter covering the latest applications and enhancements to our versatile T1 E1 Analyzer product line. Both T1 E1 Software and Hardware has been enhanced, now Version 6.22.



New Hardware Features and Software Applications :

  • tProbe™ Datacom Emulator/Analyzer Daughter Card

    GL's Datacom Emulator/Analyzer is an optional board available with GL's tProbe™ T1 E1 Analyzer USB unit. It is designed for service installation, verification, and maintenance of data communications and telecommunications equipment.

    The Datacom Emulator/Analyzer daughter card provides software selectable interfaces to emulate DTE and DCE interfaces and monitor the Datacom lines for both synchronous (SYNC), and asynchronous (ASYNC) data interfaces. The analyzer supports BER testing in ASYNC and SYNC modes. In SYNC mode, the Rx and Tx clock sources are either internal or external.

    The Datacom Emulator/Analyzer supports V.24, V.35, V.36, X.21, RS-449, RS-485, EIA-530, and EIA-530A interfaces. It can be configured as DTE or DCE to test Channel Service Units (CSUs) and Data Service Units (DSUs) used point-to-point and multi-point applications.



    tProbe™ Datacom Emulator/Analyzer Daughter Card Installed


  • tProbe™ FXO FXS Simulator Daughter Card



    The FXO port on tProbe™ allows simulation of a two-wire FXO device such as a telephone or a fax machine. This feature allows you to capture and analyze data from a two-wire telephone line, as well as to generate and transmit analog voice or data onto that two-wire line.

    Similarly, the FXS port on tProbe™ emulates a two-wire FXS service such as a telephone wall jack. This feature allows you to interface with an FXO device such as a telephone. Server commands allow you to provide standard FXS features such as monitoring for the off-hook line, sending ring signals, and providing dial tone.

  • FAX Simulator (Client Server Based)

    Client Server Based Fax Simulator module uses simple commands to transmit and receive the faxes over timeslots of  T1 E1 lines.  It supports almost all FAX standards such as V.17, V.27, V.29, V.33, and V.34.

  • CAS (Channel Associated Signaling) Analyzer

    GL's CAS (Channel Associated Signaling) Analyzer supports monitoring and decoding of CAS signaling events over T1 E1 networks. Supported CAS signaling types include MFC-R2 and R1. The real-time analysis is used to capture data on one or multiple T1 E1 lines on specified timeslot simultaneously during transmission. Users can record all or filtered traffic into a trace file. The recorded trace file can then be analyzed offline and exported to an ASCII file, or printed.

  • MAPS CLI (Command Line Interface) Server

    MAPS™, a multi purpose protocol emulation platform, can be configured as server application, to enable remote control of the application through multiple command-line based clients. Supported clients include C++, TCL, Python and others.

    Users can remotely perform all functions such as start testbed setup, load scripts, and profiles, apply user events such as send digits/file/tones, detect digits/file/tones, dial, originate call, terminate call, start and stop traffic and so on. Users can also generate and receive calls through commands. This client application is distributed along with MAPS™ Server application. Multiple MAPS™ CLI servers can be controlled remotely from single client application (such as TCL, Python, etc)

    MAPS™ TCL Client Interface (MAPS Client IFC)

    The application includes a MapsClientIfc.dll file, a packaged library that enables communication with the MAPS™ Server from a TCL environment. The advantage of such communication enables user to control MAPS™ by sending commands and receiving responses in a scripting language already familiar with many users.

Enhancements Introduced to Existing Applications:

  • Basic T1 E1 Analyzer Software Enhancements
    • Windows Client Server (WCS) - xx600 and Simplified Audio Client (SAC) - xx605 are now part of Basic Applications.
    • Additional physical level alarms: clock slip, signal level, frequency measurement
    • Clock slip display implementation for Universal and tProbe™ boards
    • FPGA enhancements - Added Clock Slips, 64-bit interval timer, and AppFPGA.map for clock slip and timer register changes

  • Protocol Analyzer Enhancements
    • Flexible summary setup improvements: collapse/expand layer/field tree, wildcard field search in the tree
    • Protocol analyzers detail view field offset display and upon selection of a detail view line (field) highlighting corresponding hex dump view bytes.

  • GSM Analyzers
    • Standard updated to 3GPP TS 24.008 V8.15.0 (2011-12)

  • SS7 Analyzers
    • High Speed Link (HSL) is supported in MTP2 layer. User is allowed to set this preference in ini file.

  • Octal/Quad T1 E1 Board Enhancements
    • Updated the Octal Board to use Message Signaled Interrupts (MSIs) on Windows systems that support MSI

      MSIs are a new type of interrupt available on PCI Express boards. A board using MSI doesn't share its interrupt with any other board on the system, so the OS will service the interrupt faster. MSIs are supported on Windows Vista and later versions. Most Linux systems also support MSIs.

  • MAPS™
    • MAPS applications version 1.4.11.8 released
    • MAPS Framework now includes -
      • Changes to Profile Handling
      • Profile selection, and Script Selection changes in Call Generation
    • MAPS ISUP Conformance Scripts - scripts are in an encrypted zip file.

  • Client Server and Introduction of FXO/FXS

    • Two new commands have been introduced to decode a wide variety of tones - These commands examine the signal arriving on the designated timeslots for the tones specified in the tone-list. A wide variety of tones may be designated, making these commands suitable for high-level analysis of calls. The command also allows you to specify the format of the timeslot data as A-Law, μ-Law, or 16-bit linear.

    • A new DSP operator that decodes tones from a source data stream has been introduced - These DSP operators examine the signal supplied by the DSP operator for the tones specified in the tone-list. A wide variety of tones may be designated, making these operators suitable for high-level analysis of signal streams. The operator also allows you to specify the format of the timeslot data as A-Law, μ-Law, or 16-bit linear.

    • Code added to the WCS FXO and FXS commands to keep FXO/FXS and VF in sync with regard to the data format in use (A-Law, Mu-Law, or 16-bit PCM). Whenever a client requests a particular format for FXO/FXS, that format is set for VF also.

    • Many new commands have been introduced that allow clients to control the operation of the FXO and FXS ports on tProbe and later platforms.

    • A new command has been introduced that allows you to set the companding/encoding option in use to the default for the system you are using. This command sets the companding (or encoding) option to the default for the system in use. This is normally μ-Law for T1 systems, and A-Law for E1 systems.

    • The default timeslots associated with FXO and FXS Input/Output operations has been changed for T1 systems. The default timeslots used for both T1 and E1 systems are now: FXO input -- Tx timeslot #1:1; FXO output - Rx timeslot #1:5; FXS input - Tx timeslot #2:1; FXS output - Rx timeslot #2:5

      Idle Code now kept in sync with FXO/FXS coding option - When you change the coding option used for FXO and/or FXS operations, the idle code used for the digital port associated with the specified FXO or FXS port is changed to correspond to the specified coding option. For A-Law and μ-Law encoding, the idle code specified in the T1/E1 Analyzer's Configuration menu will be used. For 16-bit linear PCM coding, the idle code is assumed to be zero.
In addition to the above, there have been many minor modifications and bug fixes to the T1 E1 Software. For more details, please refer to the link what's new in the current version web page.
