Advanced Telecom Infrastructure at a Train Station

Mass Transit systems rely on advanced telecommunications systems to operate efficiently, safely, provide timely information to its patrons, and provide a comfortable experience.

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 providing Advanced Telecom Infrastructure for Mass Transit Systems.

Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “Mass Transit systems rely on advanced telecommunications systems to operate efficiently, safely, provide timely information to its patrons, and provide a comfortable experience. These days mass transit systems use: Right of ways with Fiber Optic cables and SONET, OTN, or Gigabit Ethernet transmission systems, Wireless and wired broadband applications for voice, data, and video, GPS (Global Positioning System) for locating and timing, Super fast distributed and networked computers for operations, maintenance, and planning.”

He added, “GL Communications provide design, planning, and operations of communications systems that are advanced, efficient and cost effective. Our expertise cover broad spectrum of mass transit communication systems and are: Fiber optic infrastructure build-out that cover Inspections, terminations, splicing, and testing services using sophisticated tools - OTDR and precision power meters. Inspect and retrofit existing light rail vehicles to the new Automatic Train Protection (ATP) signaling system. Support installation of the Light Rail Overhead Catenary system and its integration with the traction power substations. Support and develop new LRCI software Graphical User Interface (GUI) for train control systems. And provide technical specification, system construction, management inspection and end-to-end testing services of the telecom infrastructure.”

Mr.Kulkarni further added, “GL has completed many such advanced telecom infra projects within the stipulated time and budget successfully. And to name a few of the projects undertaken and completed are: Upgrade of the Light Rail System. Evaluation of Tunnel Radio Coverage for a Metro Transit System, Comprehensive Network Management System for a Transit Administration, Agency wide Customer Information System for a Mass Transit Agency and Agency Wide Trunked Radio System for a Mass Transit and Public Safety System.“

About GL Communications Inc.,

Founded in 1986, GL Communications Inc. Provides technical consulting, engineering and testing services in wireless, telecom, and IT disciplines. Our customers include telecom wireless and landline carriers, mass transit and public safety systems nationwide. We have designed hundreds of wired and wireless telecom network systems over the past 23 years.

GL is a DBE/MBE firm certified by Maryland's Department of Transportation (MDOT), Washington Metropolitan Area Transit Authority (WMATA), Virginia Department of Transportation (VDOT), and South Eastern Pennsylvania Transportation Authority (SEPTA).

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) 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. 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.
