The SS1 Emulator (Dialer) application provides the ability to setup and dial tone sequences that make up SS1 dial digits.
Gaithersburg, Maryland (PRWEB) December 03, 2011
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 Real-time and Remote SS1 Emulator and Analyzer.
Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”Selective Signaling "SS-1" is a 2 and/or 3 digit dial system used by the Federal Aviation Administration "FAA" within their National Airspace System "NAS" Ground-to-Ground Air Traffic Control Network. It is used on leased and FAA lines between the Air Route Traffic Control Center's "ARTCC", Terminal Radar Approach Control "TRACON", Air Traffic Control Tower's "ATCT", Lockheed Martin Flight Service Hub's "FS-21", Military, National Weather Service and nongovernmental aviation facilities for the control and management of aircraft flights.”
He added, “The SS1 Emulator (Dialer) application provides the ability to setup and dial tone sequences that make up SS1 dial digits. The applications' interface includes options to setup Dial Code, and control Mask (pulse) & Space (guard) frequencies and duration, Initial, Nominal, and Final Durations, Timeout definitions, Transmit Channel, and other similar parameters related to the dial code.”
Mr. Kulkarni further added, “The GL's SS1 Analyzer detects and analyzes tone sequences that make up SS1 dial digits. Sequences of pulse and guard tones are detected, decoded, and assembled into their corresponding dial digits. The tone sequences are also verified for compliance against a "specification" parameter file which can correspond to published standards or user criteria.”
·Real-time and File-based analysis
·Generate and introduce SS1 Dial Codes on Transmit Channels using SS1 Dialer
·Control mark & space frequencies and duration, and power during transmission of SS1 Tones
·Dual monitoring capability allowing multiple instances of SS1 analyzer to simultaneously tap E and W direction traffic.
·Ability to capture either TDM or audio signals
·Configuration screens to conveniently specify the criteria used to evaluate the sequence of SS1 tones, including specifying the use of 2-digit or 3-digit dial codes. See the figure below.
·Display of received dial codes, including the characteristics of the underlying tones. Dial codes whose underlying tone sequences do not meet stated criteria are clearly identified with the erroneous tone characteristics highlighted
·Provides controls to save sets of evaluation criteria, to reinstate previously saved criteria, and to reinstate factory default (industry standard) settings
·Save results to files in a form that is widely understood by popular desktop data management and analysis tools such as Microsoft® Access and Microsoft® Excel
·Allows easy reviewing any number of selected dial code sequences and their underlying tone sequences while ongoing capture and analysis is proceeding
·Operate the SS1 Analyzer either remotely from the data acquisition site, or as on the same PC that is capturing the data
·Examine a faulty dial code at length with Review Dial Code and Spectral Graph features, even as a run is in progress
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) are all 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.
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 characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
