GL Communications Inc. conveyed today the availability of its PPP and ML-PPP Packet Data Analyzer (PDA) software.

Packet Data Analyzer (PDA) is a real-time IP and VoIP analysis tool in MLPPP Analyzer that non-intrusively captures and monitors live IP, VoIP, and IP based Video traffic.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its product PPP and ML-PPP Packet Data Analyzer (PDA) software.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ” Packet Data Analyzer (PDA) is a real-time IP and VoIP analysis tool in MLPPP Analyzer that non-intrusively captures and monitors live IP, VoIP, and IP based Video traffic.

·Segregates, captures, and collects statistics on VoIP calls (SIP / H323 / Megaco / MGCP / T.38 Fax).
·provides graphical presentation of analysis, including ladder diagrams of protocols
·monitors QoS (quality of service) on voice and video calls

Its real-time nature makes it an outstanding tool for live monitoring of VoIP traffic as well as long-term traffic statistics gathering. It can also monitor, report, analyze, and capture calls for infinite time, limited only by the finite space of your hard disk or network hard drive.”

He added, ”Detailed call statistics such as packet loss, gap, jitter, delay, RTP performance statistics, R-factor & MOS scores, and unparalleled voice band statistics can be monitored simultaneously. Sophisticated filters permit zooming and recording of specific calls of interest. All or filtered traffic can be recorded into a trace file.

Users can listen/record audio and video data of a session VoIP calls in real-time; perform power, frequency, spectral, tone and digit analysis, and video analysis with ease and precision; get an exact picture of QOS (quality of the service) and the technical adherence (adherence to the protocols specified by the standardizing authority) of the system under test.”

Some of the Important features

·Supported protocols - SIP (Session Initiation Protocol RFC 2543 and RFC 3261), Megaco RFC 3525, Megaco RFC 3015, MGCP, H323/H225, and RTP.
·Full RTP Analysis with audio capture/playback supported for all common codecs.
·Support video QoS for H.263+ and H.264 video codec; H.263 provides video capture and video conference monitoring capability, while H264 is an industry standard codec for video compression, the codec offers better compression performance over previous standards
·Provides the registration summary of each SIP registration including the user agent, registrar, status, registered time, expiry time, time to live, remaining time, and Registration Request Delay (RRD).
·Supports saving the selected calls from traffic analyzer into *.HDL or *.PCAP formats.
·T.38 Analysis - The application has the call graph and T.38 ladder diagram display. User can decode T.38 frames received over VoIP calls and can have ladder diagram for T.38 traffic flow, reassemble the fragmented data and to identify the T.30 message from it.
·Displays summary of signaling, audio, and video parameters such as Source/Destination Video Channels, Media Type, SSRC, Average Delay/Gap, Packet Counts, Media Delivery Index (MDI- (Delay Factor : Media Loss Rate)), and Frame Rate are calculated and displayed for all video calls.
·Triggered Actions and E-mail Support.
·Its ability to monitor / record audio and video data of a session to files (in QuickTime *.qt format), allows user to perform powerful video analysis.
·R factors/MOS supported for more audio and video various codecs:G.711 (µ-law and A-Law - 64 Kbps), G.711 App II (A-law and µ-law with Voice Activity Detection). G.726 (40/32/24/16 kbps), GSM (13.2kbps), G729 (8kbps),G729B (8kbps) , G.722, G.722.1 (24 kbps and 32 kbps Wideband) and more
·Provides graphical presentation of analysis, including ladder diagrams of protocols.
·Provides the registration summary of each SIP registration including the user agent, registrar, status, registered time, expiry time, time to live, remaining time, and Registration Request Delay (RRD).

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) is 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.
