Press Release: GL Announces Enhanced PacketCheck™

Gaithersburg, Maryland, USA - January 19, 2010 - GL Communications Inc. announced today the release of enhanced PacketCheck™ - a PC based Ethernet / IP BERT and throughput test tool. Speaking to press, Mr. Jagdish Vadalia, Senior Manager of Product Development said, "PacketCheck™ is very easy to use tool, and it truly takes confusion out of Ethernet and IP testing at all protocol layers - from raw Ethernet frames to IP/UDP packets. It can also be used as a general purpose network performance analysis tool for 10Mbps, 100Mbps and 1Gbps LANs and WANs". He added, "The product has been enhanced to support multistream generation and reception, PRBS pattern generation and reception, RTD (round trip delay) measurement, impairment generation, loopback at all levels, including Ethernet frames and IP/UDP packets".

Mr. Vadalia further added, "The productís simple to use GUI interface, and its powerful features compare favorably with other test sets costing significantly more. It is perfect tool for customers who are on the lookout for cost effective Ethernet / IP BERT testing tools".


Important Enhancements Introduced:

  • Multistream Generation

    PacketCheck™ has now been enhanced to generate multi stream traffic. Each stream can be configured independently and can have different attributes like direction (Tx, Rx, or Tx and Rx), bandwidth, frame size, Layer (Ethernet/IP/UDP) . On the receiving side, performance measurements like Byte Error Rate, Packet loss are calculated and reported for each stream separately.

  • PRBS Pattern Generation / Reception

    PacketCheck™ can now generate PRBS patterns e.g. QRSS, 2ˆ6-1, 2ˆ9-1, 2ˆ11-1, 2ˆ15-1, 2ˆ20-1, and 2ˆ23-1. PacketCheck™ measures and reports the Byte Error Rate, Error Status and the Sync Loss Count based on the PRBS reception.

  • Loopback Mode

    PacketCheck™ in addition to the existing Tx (Transmit only), and Rx (Receive only) and Tx_Rx (Transmit and Receive) modes, can now operate in Loopback mode. PacketCheck™ can perform loopback at the Ethernet, IP and UDP levels.

  • Calculation of Round Trip Delay (RTD)

    PacketCheck™ now calculates the average Round Trip Delay. Round Trip Delay is the total time taken for a packet to travel to the remote end and back to the point of beginning. Round Trip Delay can be calculated using 2 PacketCheck™ applications - one at the local end running in Tx_Rx (Transmit and Receive) mode and another at the remote end running in Loopback mode. Round Trip Delay is reported in microseconds.

  • Run Time Impairment Generation

    PacketCheck™ can generate various Byte level impairments at run time. Each stream can be configured to generate impairments such as Insert/Delete bytes, Change bytes etc.

Other features include:

  • Test Ethernet traffic of up to 800Mbps 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 / Transport) with on-demand bandwidth

  • Monitor Performance Statistics (Throughput, Packet loss, Out of order packets)

  • Jumbo frames are supported, in addition to all normal frame sizes from 64 bytes to 1518 bytes

  • User defined test pattern of up to 24 bytes

  • Customizable protocol headers like MAC Source/Destination address, Length/Type field, IP Source/destination address, and UDP Source/Destination Port

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.

GLís 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.

GLís 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.

GLís 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.

GLís Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GLís compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GLís 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.

GLís 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.

GLís 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.
