GL Conveys the Availability of Signaling System 7 (SS7) Protocol Simulation using Digital Central Office Switch Simulator (DCOSS)

Gaithersburg, Maryland (PRWEB) April 19, 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 Signaling System 7 (SS7) Protocol simulation using Digital Central Office Switch Simulator (DCOSS).

Speaking to media persons, Mr. Robert Bichefsky Senior Manager of the company said, The Digital Central Office Switch Simulator (DCOSS) offers the capability of simulating Signaling System 7 (SS7) digital protocol. DCOSS SS7 utilizes a user-friendly GUI in which the complex SS7 configuration can easily be created, thus allowing DCOSS SS7 to be fully functional within a few minutes.

He added, DCOSS SS7 also incorporates the flexibility to modify SS7 parameters, both at the MTP and ISUP/TUP layers as well as the ISUP/TUP message content. This flexibility ensures that the DCOSS SS7 will communicate with the system under test.

Mr. Bichefsky further added, Configuring DCOSS SS7 is quite simple, even for the most complex requirements. The DCOSS SS7 utilizes a GUI that provides the user with all required SS7 parameters. These parameters may be saved to the DCOSS database, after modification, for later retrieval.

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.

GL Conveys the Availability of its LTE Protocol Analysis and Simulation Software

Gaithersburg, Maryland (PRWEB) November 22, 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 LTE Protocol Analysis and Simulation software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, LTE (Long Term Evolution) protocol standard is the so called 4G (4th Generation) mobile standard in the rapidly evolving mobile technologies. Its distinguishing feature is an all IP infrastructure and significantly greater air interface bandwidth to the mobile handset. It was developed as an enhancement to the existing 3G UMTS System (Universal Mobile Telecommunications System) to provide users enhanced mobile radio and Internet access.

He added, The LTE air interface is a completely new system based on orthogonal frequency-division multiple access (OFDMA) in the downlink and single-carrier frequency-division multiple access (SC-FDMA) in the uplink. The system efficiently supports multi-antenna technologies (MIMO). OFDMA is considered much better at handling the varying propagation conditions seen in mobile radio. This is similar to WiMAX. In MIMO techniques, either multiple antennas can transmit the same data stream to improve data-transmission reliability or different antennas can transmit different data streams simultaneously to increase throughput.

Mr. Vadalia further added, Another significant feature of LTE is its high bandwidthup to 20 MHz. Because the usable bandwidth is scalable, LTE can also operate in the existing 5-MHz UMTS frequency bands, or in even smaller bands.

GL Conveys the Availability of its SS7 over IP (SIGTRAN) Protocol Analysis and Simulation Software

Gaithersburg, Maryland (PRWEB) November 30, 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 SS7 Over IP (SIGTRAN) Protocol Analysis and Simulation software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, GLs SIGTRAN protocol decoder software is a VoIP testing tool that permits real-time analysis, call trace, capture, and filtering of SS7 and ISDN signaling messages over IP. SIGTRAN uses a new connection oriented transport protocol called Stream Control Transport Protocol (SCTP). SCTP is at the same level but more efficient at transport than TCP, UDP, or RTP.

He added, SIGTRAN Analyzer supports SCTP, M2UA, M3UA, M2PA, SUA, IUA, SIGTRAN protocols. It is a stack of networking protocols having Stream Control Transport Protocol (SCTP) and a bunch of user adaptation (UA) layers over it.

Mr. Vadalia further added, GL’s MAPS SIGTRAN is an advanced protocol simulator/tester for SS7 simulation over IP Networks. It can simulate a Signaling Gateway and Softswitch ISUP signaling specification as defined by ITU-T standards. The tester supports testing network elements, error tracking, regression testing, conformance testing, load testing/call generation and generation of high volumes of ISUP traffic. MAPS SIGTRAN functionality covers the ITU and ANSI variant of SS7 implementing M3UA, and ISUP protocols. It is able to run pre-defined test scenarios against ISUP test objects in a controlled & deterministic manner.
