Newsletter: GL Announces tProbe™ - T1 E1 VF and Serial Data Analysis and Emulation Hardware

Welcome to another February 2011 issue of GL Communications' newsletter providing information and insight into our latest hardware platform tProbe™ T1 E1 VF and Serial Data Analysis and Emulation Hardware.

Overview

GL's new tProbe™ is an enhanced version of our popular USB-based T1 E1 VF Analyzer / Emulator. This hardware incorporates all the features of the previous analyzer such as portability, USB interface, remote accessibility, scripting, and a vast collection of optional applications. Recently tProbe™ was introduced with the following important enhancements:

  • T1 E1 Pulse Shape and Jitter Measurement Analysis

  • "Cross-port Through" and "Cross-port Transmit" Modes - these configurations make cabling with Drop/Insert and Fail-Safe Inline Monitoring very easy

  • Enhanced VF Drop and VF Insert Capabilities (including 3.5 mm or Bantam physical connection options)

  • Improved circuitry for very accurate Digital Line Level measurements

  • Ethernet interface for future standalone operation

  • Easy calibration

  • Forward thinking hardware design for future daughter board expansion applications

  • Windows XP / Widows 7 operating system support with user-friendly GUI

  • Lightweight (1.24 lbs) and small footprint (6.05" x 5.55" x 1.60")

tProbe™ comes with "basic software applications" for basic testing needs and optional software applications that extend the capability far beyond the most expensive T1 E1 VF and Serial Data testers. For example, capturing and transmitting an entire raw T1 E1 VF or Serial Data signal simultaneously on two full duplex ports, or performing ISDN emulation, or SS7 analysis, or analyzing echo and voice quality.

Enhanced Loopback Modes:

tProbe™ supports Normal (no cross-port), Cross-port Through, and Cross-port Transmit loopbacks.

Cross-port Through Loopback

This mode is similar to the standard Outward Loopback except that the signal received on Card 1 (Port 1) is transmitted out onto Card 2 (Port 2). Likewise the signal received on Card 2 (Port 2) is transmitted out onto Card 1 (Port 1). This feature allows monitoring T1 E1 lines in-line while still being protected from loss of power to the board. This mode is effected entirely thru relays and eliminates complex cabling.

Cross-port Transmit Mode Loopback

In this Mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2 (Port 2) and the data that would normally be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1 (Port 1). The receive paths are completely unaffected. This mode is particularly useful for Drop and Insert and Error Injection applications in which the board analyzes and may insert traffic running between two pieces of T1 E1 equipment. This feature also eliminates complex cabling.

Future Capabilities Include

  • 10/100 Ethernet Interface for standalone embedded applications

  • 2-Wire Daughter Board for FXO and FXS (RJ-11) connections
    • FXO - 2-Wire Calling/Answering, Caller ID, T1 E1 to 2-Wire FXO Drop or Insert, PC to 2-Wire FXO Drop or Insert
    • FXS - Ring and Battery Voltage Generation, T1 E1 FXS Drop or Insert, PC to 2-Wire FXS Drop or Insert

  • Optional DataCom Board (Dual DB-25 Connections) supporting the following DTE/DCE interfaces:
    • RS-232 (V.28)
    • X.21 (V.11)
    • RS-449/V.36 (V.10 & V.11)
    • EIA-530 (V.10 & V.11)
    • EIA-530A (V.10 & V.11)
    • V.35 (V.35 & V.28)

  • Standalone Embedded Processor Flash and Platform Flash (SDRAM 512 MByte)

  • Additional Daughter Boards planned include ADSL, Octal T1 E1, T1 E1 Switch, and many more.
