Gaithersburg, MD (PRWEB) August 11, 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 Testing and Verification of High Speed Telecom Lines before they start carrying commercial live traffic.
Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, These days telecom networks support a number of applications, including voice, data, and video. The underlying technology may be different – such as TDM, ATM, IP, even Wireless. The physical network can be copper, radio/microwave, optical fiber, or satellite. Service providers must thoroughly evaluate their networks to ensure that their availability meets customer expectations. Such an evaluation would often include testing the networks under normal operating conditions as well as testing beyond normal operational environment, often to a breaking point or close to it, called stress testing. Most operators would prefer to stress test their networks and observe their performance to have a level of confidence before putting through commercial traffic.
He added, GL has expertise to test a domestic long distance carrier lines prior to turn up. We develop a test plan covering throughput testing, continuity testing, and stress testing. Our engineers programme test equipment to generate traffic with varying packet sizes and inter-packet gaps. Sending smaller packets with minimal gaps stresses network elements that switch packets and also tests any latency issues. Longer packets, scrambling, and octet stuffing and de-stuffing were also tested. An ideal way to generate the maximum stress on circuits under test is to transmit an IP packet, which has both a random packet size and gap. Internet traffic may, typically, transmit any of the definable packet sizes and gaps. However, in practice, it is more common to see fewer variations in the packet size as more packets are transmitted. GL’s test plans provide a packet stream that closely approximate real life traffic distribution as well as extreme ranges.
Mr. Kulkarni further added, Designing and conducting stress tests are specialty areas that are best handled by experts. Our engineers have extensive experience to perform the entire gamut of testing including – design test plans, write test procedures, conduct tests, and document test results. With extensive experience in telecom testing, GL offers a comprehensive suite of testing services to evaluate complex telecom networks. These services are intended to insure that the performance and reliability of networks are completely understood prior to decisions to start carrying live traffic.

GLs 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.
GLs 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.
GLs 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.
