Press Release: GL Releases PacketProbe™
A CPE Based VoIP Monitoring Solution

Gaithersburg, Maryland, USA - July 22, 2010 - GL Communications Inc., announced today the release of its latest packet product PacketProbe™ - A CPE based VoIP Monitoring Solution. Addressing a press conference, Mr. Jagadish Vadalia, Senior Manager, Product Development said, ďGL's PacketProbe™ is an advanced CPE (Customer Premise Equipment) based VoIP monitoring reporting and diagnostic appliance, stemming from GLís suite of market leading voice analysis tools. It can fit seamlessly into any existing standards based management or reporting environment, such as SNMP or RADIUS. PacketProbes™ can provide vital voice call quality statistics, Call Detail Records and Quality of Service metrics at the end of each call. Optionally, GL offers its own Monitoring and Reporting System called PacketScanWeb™Ē.

He added, ďPacketProbe™ can be used to ensure successful deployments, and can also be used to help with network design, ensuring that the most efficient topologies are implemented. Additionally, PacketProbe™ can be used for ongoing network management to allow for maximum customer uptime and to allow the Service Provider to meet or exceed their Service Level GuaranteeĒ.

Mr. Vadalia further added, ďPacketProbe™ can be integrated into an intelligent third-party network device, like a router for example, or it may be deployed as a stand-alone appliance. As a stand-alone appliance, PacketProbe™ is completely transparent to your existing network and is able to interface with WAN or LAN. It can even function as the demark point between WAN and LAN. In any scenario it passively monitors VoIP traffic and produces real-time per call and per-stream voice quality metrics necessary for network administrators to isolate and diagnose voice quality problemsĒ.

He added, ďPacketProbe™ has the real-time monitoring and reporting capability and can report call metrics to a local console or to a centralized database via industry standard protocols like TCP/IP, SNMP, and RADIUS. A Network Management System (NMS) like GLís PacketScanWeb™ would then allow many simultaneous users to read and query the database using a conventional web browser. Multiple PacketProbe™'s coupled with GLís PacketScanWeb™ can provide complete and immediate network-wide voice quality visibilityĒ.

Main Features:

  • Reports Call Detail Records (CDR) and Quality metrics per call/stream, including:

    • Call summary statistics including caller number, callee number, start time, duration, etc.

    • Listening and Conversational Quality Mean Opinion Score (MOS-LQ, MOS-CQ)

    • Listening and Conversational R factors (R-LQ, R-CQ)

    • R-factors for burst and gap conditions Ė R-Burst, R-Gap

    • For narrowband and wideband voice - R and MOS Scores

    • Degradation factors - % degradation due to loss, discard, delay, gap, jitter, and codecs

    • Packet Ė Packet Delay Variation (PPDV - RFC3550), Mean Absolute Packet Delay Variation (MAPDV - G.1020) and Y.1540 Jitter Metrics

  • Reports CDR with Quality Metrics for each stream

  • Automatically detects active VoIP calls based on VoIP call signaling or RTP session. Supports SIP, MGCP, MEGACO, H.323/H.255

  • Distributed network architecture

  • Call Quality analysis using optimized ITU-T G.107 with ETSI TS 101 329-5 Annex E

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.
