GL Announces Enhanced T1 E1 Jitter and Pulse Mask Measurement Solutions
GL Communications Inc., announced today its enhanced T1 E1 Jitter and Pulse Mask Measurement Solutions.
- (1888PressRelease) June 22, 2011 - Gaithersburg, Maryland, USA - Addressing a press conference, Mr. Jagdish Vadalia Senior Manager of Product Development said, "Jitter, 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. GL's Jitter Measurement module allows evaluation of jitter on either a tick-by-tick or a cumulative basis.
He added, "Now, the Jitter measurement can be performed through commands with the Windows Client-Server application as well. The jitter ranges can be monitored on a specified port using simple commands by a client application."
Mr. Vadalia further added, "It is quite common for T1 E1 signals, within a central office environment or an enterprise telecom room, to NOT meet pulse mask requirements due to interference, too long or short cable lengths, improper impedances, or simply poor transmitter design. In such cases, pulse mask compliance is very useful in diagnosing problems.
GL's tProbe™ T1/E1 Analyzer and Universal T1 E1 Cards have pulse shape measurement capability. Software has been developed to determine if the pulse shape fits within a "pulse mask" as specified by standards ITU G.703 and ANSI T1.102-1993. The software is available in both visual and tabular formats."
He added, "WCS Pulse Mask-The Pulse Mask Client-Server application in Universal boards is used for detection, monitoring, and plotting of transmitted pulses. Some of the commands supported are CheckPulseMask, validate pulse, stop pulse mask validation, and others. Pulse Mask will also return all error and warning message to WCS client as task error or warning message."
Important Jitter Measurement Features
•Easy, accurate, visual pulse shape and jitter measurement for T1/E1 signals (only available with Universal T1/E1 cards and tProbe™ T1/E1 analyzer)
•Provides an option to select T1 or E1 port for monitoring and the frequency range of interest
•Supports One-Shot capture and Repeated Capture options for jitter measurement
•Jitter generation (coming soon)
Important Pulse Mask Compliance Features
•Plots the pulse measured within a predefined template
•Compares the incoming T1/E1 pulses against the pulse mask display
•For T1 pulses, the x-axis measures time in unit intervals (UI), while for E1 pulse, the x-axis measures time in nanoseconds (ns),
•The y-axis measures the normalized amplitude in volts.

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 measurements.
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 monitoring systems.
