Gaithersburg, Maryland (PRWEB) May 08, 2012

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 PacketGen – SIP Call Generator Software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager said, PacketGen is a PC-based real-time VoIP bulk call generator (including both SIP signaling and RTP generation) for stress testing and precise analysis of the VoIP network equipment. PacketGen 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 generating more than 1000 simultaneous calls.

He added, GL’s PacketGen breaks ground with high density performance on a Duo Quad Core PC, it can support 1000

GL Conveys the Availability of its T1 E1 Error Insertion and Bulk Delay Application

Gaithersburg, MD (PRWEB) November 09, 2012

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 T1 E1 Error Insertion and Bulk Delay Application.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, Simulating bulk delay and errors like that found in real networks can help optimize the performance of applications. GL’s USB based or PCI Card based T1 E1 Analyzers can easily simulate such conditions. For example: At what delay does the application under test suffer throughput degradation due to ARQ Automatic Repeat Requests, at what error rates does voice performance on compressed codec circuits start to degrade, how good is error correction when the underlying uncorrected error rate is 10E-5, how to simulate the error characteristics of a microwave circuit, a copper T1 line, a fiber optic transmission line, Does encryption multiply the inherent error rate of the circuit and by how much and so on..

He explained, The Error insertion application permits inserting single, fixed, automatic, random, and burst error into the incoming bit stream. A block diagram, GUI, and schematic of the function is provided for Error Insertion application, ensure that the analyzers framing format configuration should be set according to the input signal framing format. As shown in the diagram the input to the T1 Card is fed back to the output after passing through the error insertion logic. When the aforementioned feature is used in conjunction with Cross Port Transmit, introducing delays and errors is extremely easy.

In the Cross Port Transmit Mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2 (Port 2) and the data that would normally be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1 (Port 1). The receive paths are completely unaffected. This feature also eliminates complex cabling.

Mr. Kulkarni further explained, Bulk delay is an added feature in Error insertion application, that allows users to apply delay on the entire T1 E1 trunk (full multi-frame) of 1.544Mbps (T1) pipe or 2.048 Mbps (E1) pipe. This helps to simulate network delay along the T1E1 links. After selecting or adjusting the delay, the Delay will fill a buffer and begin transmitting the signal; this will cause the T1 or E1 multi-frame signal to briefly lose sync when applying the delay.

He added, Bulk delay can be applied in either microseconds or milliseconds units and delay can be varied from 0 to 169.77mSec or 69 to 169845

GL Announces Single and Bulk Fax Simulation Over T1 E1 FXO FXS Lines

Gaithersburg, Maryland, (PRWEB) November 15, 2012

GL Communications Inc. announced today the release of its latest Single & Bulk Fax Simulation Over T1 E1 FXO FXS Lines.

Speaking to reporters, Mr. Jagdish Vadalia, Senior Manager for Product Development of the company said, Ordinary telephone lines can be used for voice, data (modem), and for fax. Believe it or not fax is still very popular. No business can be without a fax machine and some businesses, like banks, rely heavily on fax transmission for transactions involving money because faxes are considered legal documents.

He added, GL has recently introduced Single and Bulk Call Fax Simulator. This software is capable of transmitting and receiving over many T1 E1 timeslots or through two-wire FXO and FXS lines. The software can emulate many virtual fax machines – Transmitter as well as Receiver. All variations are supported. Fax Simulator can be used with any GL Protocol Emulation tools such as MAPS CAS Simulator, MAPS ISDN Simulator, and MAPS SS7 Simulator to simulate complete real time Fax calls.

Mr. Vadalia added, Using GL’s versatile hardware product line, various fax testing scenarios can be simulated: Bulk Fax tesing over many T1 E1 lines (100′s of timeslots) with our Octal T1 E1 Cards, or single FXO and FXS lines on our versatile tProbe platform, or hundreds of FXO FXS lines with our High Capacity Analog 2-Wire platform.

Fax Emulation Applications

Typical applications of our Fax Emulation software are load testing of fax servers, qualification testing of T.38 Gateways, testing of ATAs (Analog Terminal Adapters), testing of fax machines, and many more. Features and applications are:

Load Testing sending or receiving up to hundreds of faxes simultaneously; one end can send and receive simultaneously on different timeslots; over many T1 E1 lines; over many FXO or FXS lines; any signaling protocol can be used such as PRI ISDN, SS7, or CAS
V.34 Testing there are many fax modulations and V.34 is the fastest, permitting many pages to be transmitted quickly
High Speed / Low Speed fax protocol consists of low speed handshaking and high speed image transmission
Multiple Pages single or multiple page fax transmission is supported
With or without ECM Error Correction Mode permits the retransmission of erred pages.

New Fully Digital 800 Watt Bulk Front-End Power Supply from Emerson Network Power Features 80 PLUS Gold Standard Efficiency

Carlsbad, CA (PRWEB) December 05, 2012

A new 800 watt bulk front-end power supply from Emerson Network Power, a business of Emerson and the global leader in enabling Business-Critical Continuity, meets the 80 PLUS Gold standard for efficiency. The DS800SL-3 power supply has an exceptionally high efficiency of 92 percent when operating at half-load from a 230 Vac input, combined with a typical power factor in excess of 0.99.

With a high power density of 19.05 W/in3 (1.16 W/cm3) in a slim-line rack-mounting package, DS800SL-3 power supplies enable system designers to minimize space requirements in enterprise servers and similar space-constrained applications.

The new DS800SL-3 is a fully digital design; it features a built-in I2C serial bus interface and uses the industry-standard PMBus communications protocol. Developed primarily for systems employing distributed power architectures, the power supply has a wide input voltage range of 90 to 264 Vac and is rated for 800 watts output power. The main 12 Vdc payload output is programmable by plus/minus 10 percent, and can deliver up to 65.7 A continuously. An auxiliary always on 5 Vdc output, rated at 2.4 A, is also provided for powering server management circuits. Both outputs are tightly regulated, have no minimum load requirement, and offer remote sensing the 12 Vdc output can compensate for a load bus drop of up to 200 mV.

Opposite-end ac input and dc outputs facilitate fast replacement in the field, and the dc output card edge connector is compatible with the Intel
