Newsletter: GL Announces tProbe™ - T1 E1 VF and Serial Data Analysis and Emulation Hardware
Gaithersburg, Maryland, USA - February 14, 2011 - GL Communications Inc. announced today the release
of its latest hardware platform tProbeTM– T1 E1 VF and Serial Data Analysis and Emulation Hardware. Speaking to
newsmen, Mr. Jagdish Vadalia, Senior Manager of Product Development at GL, said,” 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”.
He added, “Recently tProbe™ was introduced with the following
- 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")
Mr. Vadalia explained , “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”.
He added, “Our latest hardware platform tProbeTM– T1 E1 VF and Serial Data Analysis and Emulation Hardware
provides customers an inexpensive and feature rich tool to analyze and test T1 E1 VF and Serial Data circuitry”.

Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture,
storage, and convenient features like portability, remotability, and scripting.
GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire,
and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband
traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303,
Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products
provide astonishing capacity and capture capability up to and including gigabit speeds.
GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as
frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729,
AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording.
The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput
parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS,
PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice
Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE
networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal
GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic
echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted
in the industry.
GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice
compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and
other distortions are easily assessed and accurately measured.
GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional
T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers
provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1,
T3, E3, and many others.
GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An
open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized
or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based
