GL Communications Inc., announced today the release of their newest product PacketCheckTM – A Software Ethernet Tester.

Ethernet Tester and Analyzer

The application makes use of the network interface card (NIC) in the PC to transmit and receive Ethernet packets over the network. Throughput up to 500Mbps can be easily tested

GL Communications Inc., announced today the release of their newest product PacketCheckTM – A Software Ethernet Tester. Announcing the news to the press, Mr. Vijay Kulkarni, CEO of the company said, "GL's newest product, PacketCheck™ is a PC based Ethernet test tool that is designed to check frame transport ability and throughput parameters of Ethernet and IP networks. It can be used as a general purpose Ethernet performance analysis tool for 10Mbps, 100Mbps and 1Gbps Ethernet local area networks". He Added, "The application makes use of the network interface card (NIC) in the PC to transmit and receive Ethernet packets over the network. Throughput up to 500Mbps can be easily tested".

Mr. Kulkarni further added, "PacketCheck™ allows generating full duplex (transmit and receive) IP, UDP, or Ethernet frame traffic with on-demand bandwidth (up to 500Mbps) control. Also included is BER testing capability with provision for user defined test patterns. Users can control the duration of traffic, and specify the format length, type, source IP and MAC address, and destination IP and MAC address. The software allows monitoring end to end performance statistics such as total packets, packet loss, out of sequence packets, error packets, correct pattern frames, pattern sync status, and protocol statistics (Broadcast / Unicast frames, IP/Non IP frames etc). It can operate on any of the three layers - Layer 2 (Data Link), Layer 3 (Network), and Layer 4 (Transport) of the OSI reference model."

Important features:

•Test Ethernet traffic of up to 500Mbps bandwidth
•Generates full duplex IP, UDP, or Ethernet frame traffic to transmit and/or receive traffic on any of the three layers (Data Link / Network layer / Transport) with on-demand bandwidth
•Bit-error-rate testing (BERT) on layer 2, layer 3, and layer 4 with detailed runtime statistics for both Tx and Rx
•Customizable 2 bytes test patterns
•Customizable protocol headers like MAC Source/Destination address, Length/Type field, IP Source/destination addresses, and UDP Source/Destination Port
•64 bytes to 1518 byte frame lengths supported
•Supports end-to-end (Tx and Rx) performance statistics monitoring
•Capacity to control the traffic duration with Tx and/or Rx run-time settings in seconds
•Ethernet Level BERT, Tx and Rx frame statistics
•IP level BERT, Tx and Rx packet statistics
•UDP level BERT, Tx and Rx packet statistics
•Generates test report summary in a log file
•Provides NIC performance details, such as, Received OK frames, Buffer overflow frames, and Received error frames

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, STM-1, 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, etc.), and with capacities up to thousands of channels.

GL's VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes a Software Ethernet Testing capability that checks frame transport and throughput parameters of Ethernet and IP networks.

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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1/E1/T3/E3/OC-3, VoIP, Wireless, Landline, etc.) are all available.

GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wirelss 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, RS422 / RS530, 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
