GL Conveys its Expertise in Climate Controlled Outdoor Cabinets for Communications Systems

Gaithersburg, Maryland (PRWEB) July 26, 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 Climate Controlled Outdoor Cabinets for communications Systems.

Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “Climate controlled outdoor equipment cabinets play an important role in insuring reliable and quality communications links. Outdoor cabinets that house today's modern communications systems are very different from their earlier versions. Present-day cabinets are home to a number of state-of-the-art electronic systems and components used for public communications, intelligent transportation systems, CCTV surveillance, and other equipment related to homeland security for transit and public safety requirements.”

He added, “The electronic systems include computers and servers consisting of microprocessors, fiber optic devices, Ethernet routers and switches, uninterrupted power supply units, and other semiconductor components. They are very susceptible to high temperatures and high humidity. Overheating and condensation would shorten their life expectancies and cause major failures. Hence, they require an environment controlled for heat and humidity for proper functioning.”

Mr. Kulkarni further added, “Two basic technologies are available for cooling an outdoor cabinet, a passive 'heat exchanger', or active (Freon-compressor type) air conditioning. This is apart from the traditional fan or blowers used in some cases. A passive heat exchanger consists of a fluid-filled 'heat pipe' assembly. Typically, passive heat exchanger units are only good for very minor cooling tasks (around 600 BTU or less) with very little heat producing equipment inside the cabinet, and in very moderate climates. Even with minimal equipment installed in a cabinet, a 600 BTU 'heat exchanger' would not come close to cooling adequately when outside temperatures reach 80°F or more. Active air conditioning becomes a must for anything more than that.”

Mr. Kulkarni added, “Designing a modern-day communications cabinet is complex and requires extensive knowledge and experience. Some factors that go into design considerations are: Size and type of communications equipment, Equipment placement inside cabinet, Mounting systems for the equipment, Total estimated power dissipation, and Site location requirements and more.

Our experts study the environmental conditions inside the cabinets and leverage their experience to design and specify climate controlled outdoor cabinets. Our solution leads to a more controlled environment inside the cabinet and ensure that our customers' telecommunications links continue to be highly reliable even under adverse weather conditions.”

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.
