GL Conveys the Availability of Its OC-3 STM-1 and OC-12 STM-4 Analyzer for Packet Over SONET (POS) Mode
(PR Web Via Acquire Media NewsEdge) Gaithersburg, MD (PRWEB) April 07, 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 the availability of its product OC-3 STM-1 and OC-12 STM-4 Analyzer software for POS mode.
Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”Packet Over SONET (PoS) is a highly scalable layer 2 protocol that uses PPP encapsulation to carry IP packets directly in SONET/SDH networks. Currently it carries a majority of the Internet traffic because it can make efficient use of existing SONET infrastructure. The protocol uses practically all optical interfaces as defined by the Internet Engineering Task Force (IETF).”
He added, ”GL’s OC-3 STM-1 and OC-12 STM-4 analyzer is referred to as LightSpeed1000™ analyzer supports Packet over SONET / SDH (PoS) at OC-3 STM-1 and OC-12 STM-4 at full rates over dual interfaces. Access, capture, analysis, and emulation of PPP and HDLC, all carrying IP traffic in real-time makes this card useful to many applications including Routing, Deep Packet Inspection, and other Internet traffic applications. Multiple cards can be installed in a PC making it scalable to monitor or generate OC-3 or OC-12 traffic on multiple ports. Each port on a card can work independent of others, which extends analyzer's flexibility as test equipment.”

·Packet statistics: Tx/Rx Byte Count, Tx/Rx Packet Count, Rx FCS Error Count, Rx Abort Packet Count, Rx Minimum and Maximum Packet Length Violation Error Count
·IP Statistics: IP Packets Received, IP Checksum Errors, , UDP data over IP Layer frame count
·Loopback options include: Software Rx-to-Tx memory loopback, line loopback, diagnostic loopback, and PL3 loopback options
·Bit Error Rate Test module supports generation and analysis of payloads at wire speed. Supports many PRBS patterns and user-defined patterns as payload. Report on error count, error rate, sync loss, SES, and others is provided
·Capture data to file on individual ports, limited only by hard disk size
·PPP protocol analysis supported on single or multiple ports
·Memory based transmit/receive test with incremented sequence number based data for each packet
About GL Communications Inc.,
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
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.
