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

Bulk Fax Simulation & Analysis over T1 E1 FXO FXS Lines.

Our Fax Simulator is capable of transmitting and receiving over many T1 E1 timeslots or through two-wire FXO and FXS lines.

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.
  • Alaw and µlaw – In TDM networks, USA uses µlaw and the rest of the world use Alaw – both coding standards are supported
  • Over T1 E1, PSTN, IP – Fax transmission may be over T1 E1 digital lines, over PSTN FXO / FXS lines, or over VoIP (packet) networks

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.
