GL Announces T1 E1 Jitter and Pulse Mask Measurement Solutions
Gaithersburg, Maryland, USA - March 02, 2009 - GL Communications Inc., announced today T1 E1 Jitter and Pulse Mask Measurement Solutions. Addressing a press conference, Mr. Jagdish Vadalia Senior Manager of Product Development said, "Jitter along with wander and frequency drift are major impairments of clocks in synchronous systems. Jitter is the time discrepancy between the time of arrival of a clock pulse and its theoretical arrival time. Jitter arises from a number of sources, including aging of clock circuits, thermal and loading effects, Doppler shifts, and de-multiplexing from higher bit rate data streams". He added, "GL's Jitter Measurement module allows evaluation of jitter on either a tick-by-tick or a cumulative basis. Technically, cumulative jitter is of primary importance as network equipment must cope with the cumulative jitter".
Mr. Vadalia further added, "GL's solution provides pulse mask compliance testing using Pulse Mask Display for both T1 and E1 applications as specified by standards ITU G.703 and ANSI T1.102-1993. The software is available in both visual and tabular formats. Tabular formats are convenient for automation and scripted test environments".
Important Jitter Measurement Features
oEasy, accurate, jitter measurements for T1 E1 signals (Universal T1 E1 cards only) oOption to select T1 or E1 port for monitoring and jitter frequency range oSupports One-Shot capture, Repeated Capture, and Save options oResults of measurements in *.CSV file oSupported on Windows 2000/XP/Vista oJitter generation (coming soon)
For further information, please refer to http://www.gl.com/jitter-measurement.html web page.
Important Pulse Mask Compliance Features
oPlots the pulse measured within a predefined template oCompares the incoming T1 E1 pulses against the pulse mask display oFor T1 pulses, the X-axis measures time in unit intervals (UI); for E1 pulses, the X-axis measures time in nanoseconds (ns) oY-axis measures the normalized amplitude in volts oStandards compliant with ITU G.703 and ANSI T1.102-1993 oSoftware is available in visual and tabular formats

About GL Communications Inc.
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, 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, STM-1, 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, etc.), and with capacities up to thousands of channels.
GL's VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes a Software Ethernet Testing capability that checks frame transport and throughput parameters of Ethernet and IP networks.
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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1/E1/T3/E3/OC-3, VoIP, Wireless, Landline, etc.) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wirelss 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, RS422 / RS530, 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
