GL Announces High Capacity PacketGen(TM) Software
Gaithersburg, Maryland, USA - October 06, 2009 - GL Communications Inc. announced today the release of its enhanced VoIP Testing tool PacketGen(TM) - a software based VoIP Testing tool for real-time VoIP bulk call generation, stress testing, and analysis of VoIP networks and equipment. Speaking to the press, Mr. Karthik Ramalingam, Project Manager said, "PacketGen(TM) is based on a distributed architecture with SIP and RTP software cores modularly stacked in one or many PCs to create a scalable high capacity test system - capable of more than 1000 simultaneous calls with both SIP and RTP generation. He added, "This performance is with a G.711 codec but other codecs may provide higher call densities. PacketGen(TM)'s distributed architecture as well as greater PC performance are key factors in achieving the higher call densities.".
Mr. Ramalingam further added, "Up to 20 SipCores can be run on the same PC or a multiple PC system. All 20 SipCores can be remotely controlled from a single system".
Other Important features:
o New Codec Support with an enhanced script editor
New codec support for EVRC and EVRCB with Silence Suppression and G.711 Appendix II has been added. RTP script editor is enhanced with a new feature - Define User Tone. The feature help users define multiple tones before monitoring receive tone action. The 'Tone Label' helps in identifying the type of tone detected. The user can trigger some actions like IVR applications based on the tone detected.
o Reliable Provisional Responses (RPR)
The ability to send "reliable provisional responses" and start early media actions has been added. We have two options in Reliable Provisional Responses Viz: Required and Supported.
o Digit Detection Qualifications
We support both Time and Power qualifications for digit detection. The detected digit's On time or power MUST be >= to the value set by user for the digit to be detected.
o Option to turn on/off sending outband digits information in signaling
This new option allows user to decide whether to send outbound digit codec information in the SIP signaling. If option is true, then the RFC 2833 codec will be included in the m= line of the outgoing SDP (either in an outgoing INVITE or in an outgoing 200 OK in response to INVITE). Also, corresponding a=rtpmap and a=fmtp attribute lines are added. The new command has been added to control the outbound info as in GUI. This option helps user control sending/detecting of outbound digit codec in the SIP signaling. If the option is set to 'true' then PacketGen(TM) can detect Outbound digits. If the option is set to 'false' the application cannot detect outbound digits.
o RTP Script Editor Changes
Script Editor has been enhanced with a Monitor Tone option that helps the user to detect single/dual frequency tones. The NAT Address option has also been modified so that the PacketGen(TM) is configured to send only NAT Address in a contact header while sending any request.
o Command Line Interpreter
New command line has been added to set/reset the required or supported flag. It has also been modified to read the G726 Packing Type from the User Agent configuration automatically.
o Option to set EVRC Packing Format (Using INI File)
The application supports both LSB and MSB packing for EVRC payload. User can choose the value by editing the appropriate (RTPConfig.ini) file.
o UA Configuration
G726 packing type has been moved from SIP Call parameters to Media parameters. G726 codec options dialog now displays the Packing Type. Default value is set to RTP.

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 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.
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.
