tProbe™ – T1 E1 VF and Serial Data Analysis and Emulation Hardware

מאפיינים מרכזיים

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 ShapeJitter Measurement Analysis and Jitter Generation
  • tProbe™ FXO and FXS board allows simulating FXO and FXS ports; FXO port to simulate a two-wire FXO device such as a telephone or a fax machine and the FXS port on tProbe™ to emulate a 2-wire FXS service such as a telephone wall jack.
  • tProbe™ Datacom Analyzer board supports V.24, V.35, V.36, RS-449, RS-485, EIA-530 and EIA-530A interfaces and can be configured as DTE or DCE to test Channel Service Unit (CSU) and Data Service Unit (DSU) entities
  • Software selectable T1 or E1 interface along with Drop and Insert
  • Monitor the T1/E1 line conditions such as frame errors, violations, alarms, frequency, power level, and clock (or frame/bit) slips.
  • TDM, ISDN, SS7 – High Density Voice
  • VoIP, Frame Relay, Multilink Frame Relay, PPP and Multilink PPP, HDLC
  • Physical layer analysis includes ability to send alarms and errors via SNMP Traps
  • Routing and Bridging emulation over Multi T1/E1 WAN interfaces using MLPPP (Multi Link PPP) and MFR (Multi Link Frame relay) protocols
  • Call Recording, Generation, and Monitoring for hundreds to thousands of calls in one platform
  • Capable of simulating as well as decoding and demodulating fax calls over T1/E1 lines using Fax Simulator andFaxScan™
  • Windows® and Linux Drivers for Open Source Applications
  • Supports both 32-bit and 64-bit Windows® operating system.
  • "Cross-port Through" and "Cross-port Transmit" Modes – these configurations make cabling with Drop/Insert and Fail-Safe Inline Monitoring very easy
  • Support for all  "basic applications" and "special applications"
  • Comprehensive Analysis / Emulation of Voice, Data, Fax, Protocol, Analog, and Digital signals, including Echo and Voice Quality testing
  • 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
  • Lightweight (1.24 lbs) and small footprint (6.05" x 5.55" x 1.60 ")
  • Switchable Line Level or Microphone input using 3.5 mm or Bantam physical connectors
  • Enhanced VF Drop and VF Insert Capabilities using 3.5mm Balanced (Stereo), or Unbalanced (Mono) physical connections.
  • Includes individual speakers (one speaker per card).
  • The VF Tx and Rx impedance for tProbe™ analyzer supports software selectable 135, 150, 600, or 900 Ohm terminations. Additionally, the VF Rx impedance supports New High Impedance Monitor Termination (>50K Ohms), and external Microphone and Headset (Mic/HS) impedance .
  • VF Tx Gains for tProbe™ analyzer ranges from -12 dB to +59.5 dB in 0.5 dB steps, and VF Rx Gains for tProbe™analyzer ranges from -63.5 dB to +9 dB in 0.5 dB steps.
