Gaithersburg, MD (PRWEB) August 02, 2012
GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today its expertise in designing Video Surveillance and Passenger Information Systems for Mass Transit Agencies.
Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “The goal of Video Surveillance and Passenger Information Systems (PIS) that many Mass Transit agencies use is of transit network operation and passenger safety. In general, such surveillance and information systems help: Provide patrons with a 24 x 7 contact point in case of emergency, allow for important announcements to patrons, allow for displays using LED signs for special events and train or bus schedules, assist police to prevent and discourage crimes, and monitor transit network operations.”
He added, “Mass transit agencies in many countries are increasingly using Video or Close Circuit Television (CCTV) surveillance to enhance public security within the transit network. Experience shows that video surveillance has been successful in reducing and preventing crimes and helpful in prosecuting individuals caught in the act of committing a crime by having access to recorded evidence of crime scenes. Overall, operational cost savings are realized. Video surveillance systems can passively record and play back video as needed or be actively monitored by security personnel.”
Mr. Kulkarni further added, “CCTV Surveillance and PIS have evolved from standalone displays and audio to multimodal integrated systems to keep passengers informed and safe within public transit systems, such as trains, station platforms, buses and bus shelters. Left Objects Detection (LOD) feature of CCTV systems have become very popular and useful to prevent serious crimes such as early detection of timed-release explosive materials. Modern systems incorporate multiple communications technologies, including IP networks, wireless networks, video streaming, advanced visual displays, public address, emergency intercom etc. They are controlled and managed from a centralized operations center and deliver real time information for remote monitoring and control.”
Mr. Kulkarni added, “Transit agencies need to consider many factors while planning and implementing passenger information and security systems. They include: Customer satisfaction and ADA (Americans with Disability Act) compliance, use of modern State-of-Art technology solutions, system scalability for future expansion and upgrades, passenger growth and convenience, advertising potential, capital expenditure and long term sustained cost savings and reduced recurring expenditure (manpower, infrastructure maintenance, transmission bandwidth etc.).
GL’s expertise span in designing CCTV Surveillance Systems, station emergency telephone systems, public address (PA) and LED sign systems and more.”

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) is 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.
