Gaithersburg, Maryland, USA - August 17, 2010 - GL Communications Inc., announced today the release of its newest product PacketExpert™ - A Quad port wirespeed Ethernet/Packet Tester. Addressing the press conference, Mr. Jagadish Vadalia, Senior Manager said, " PacketExpert™ is a quad port wirespeed Ethernet/Packet Tester. It supports 4 Gigabit Ethernet ports and connects to the PC through a USB 2.0 interface. Each GigE port provides independent Ethernet/IP testing at wirespeed for applications such as BERT, RFC 2544, and many more. It truly takes confusion out of Ethernet testing at all protocol layers - from raw Ethernet to IP/UDP packets. It can also be used as a general purpose Ethernet performance analysis tool for 10/100 Mbps or 1 Gbps Ethernet local area networks. Two of the 4 ports have both Electrical and Optical interfaces, enabling testing on optical fiber links as well".

He added, "A BERT application measures Bit Error Rate on Raw unframed Ethernet (Layer1), framed Ethernet (Layer2), IP and UDP data streams. Various PRBS patterns such as 2⁹-1, 2¹¹-1, 2¹⁵-1, 2²⁰-1, 2²³-1, 2²⁹-1, 2³¹-1 are supported. Also All Ones, All Zeroes, Alternate Ones and Zeroes patterns are provided as well as user-defined test patterns ranging from 1 bit to 32 bits. PacketExpert™ supports user-defined options to configure Ethernet/IP/UDP header parameters, including VLAN, Frame Size, and Rate".

Mr. Vadalia further added, "Per RFC 2544 specifications, PacketExpert™ supports Throughput, Latency, Frame Loss Rate, and Back-to-Back tests. It includes various parameter configurations such as Test Selection, Frame Sizes, Unidirectional/Bidirectional, Number of trials, Trial Duration, and many more. User-defined options to configure various packet header parameters, like MAC addresses, IP addresses, UDP ports etc. Results are displayed in both tabular as well as graphical format".

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) are all 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.
