GL Releases PacketProbe™

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, "GL's PacketProbe™ is an advanced CPE (Customer Premise Equipment) based VoIP monitoring reporting and diagnostic appliance, stemming from GL's 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™".    

Mr. Vadalia further added, "PacketProbe™ 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 problems".

Important 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 - 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 Lost, Discarded, Out-of-sequence, Duplicate packet statistics Round Trip Delay (RTD) statistics Codec and SSRC identification Packet - 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 Supports Japanese TTC JJ201.01 VoIP monitoring requirements CODEC's supported include G.711, G.723, G.726, G.728, G.722.x, G.729A, G.729B, GSM, FR etc

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 VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, 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 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) 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.

The broadest range of simulation

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 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
