T1 E1 Analyzer software

Our T1 E1 Analysis suite of products continue to provide the most comprehensive analysis and emulation capability of any product on the market. Any traffic over T1 E1 lines including voice, fax, modem, signaling, mobile, IP, VoIP,and more is addressed.

GL Communications Inc. announced today the release of T1 E1 Analyzer Software Version 6.14. Addressing the media, Mr. Vijay Kulkarni, CEO of the company said, "Our T1 E1 Analysis suite of products continue to provide the most comprehensive analysis and emulation capability of any product on the market. Any traffic over T1 E1 lines including voice, fax, modem, signaling, mobile, IP, VoIP, ATM, and more is addressed. We continue to satisfy the requests of each and every customer.”

He continued with some of the major applications, “Multi-Link Frame Relay Emulator – Frame Relay and Multi-Link Frame Relay can be emulated on up to 16 T1 E1 lines using GL’s client-server based MFR Emulator GUI or command line scripts.

Inverse Multiplexing over ATM (IMA) Emulator - Inverse Multiplexing over ATM (IMA) can be emulated on up to 16 T1/E1 lines using GL’s optional client-server based IMA Emulator software module.

Channel Associated Signaling (CAS) Emulator - GL’s MAPS™ CAS (Channel Associated Signaling) Emulator is an advanced protocol simulator for simulating CAS signaling over TDM (T1 E1). MAPS™ CAS automates the testing procedure with the ready scripts on single, multiple, or all timeslots. Calls are established, once the signaling information such as the signaling bits, MF, DTMF, or tones are detected. All CAS protocols, including wink-start, loop-start, ground start, R1, MFC-R2, etc. are supported, including custom CAS protocols.

Mobile Application Part (MAP) Emulator - GL’s MAPS™ MAP (Mobile Application Part) Emulator is an advanced protocol simulator to simulate MAP signaling over D & H interfaces in GSM/UMTS networks as defined by 3GPP standards.

Multi-Link Point-to-Point Protocol (MLPPP) Emulator - GL’s MAPS™ MLPPP Emulator is an advanced protocol simulator for PPP and MLPPP simulation over TDM (T1 E1 lines). Ready scripts are capable of generating and receiving MC-MLPPP/PPP traffic (with or without impairments), perfect for automating the test and regression procedures.

Fax Decoder/Demodulator (FaxDD)

Fax Decoder/Demodulator, an optional module within VBA, can be used to decode both 2-wire and 4-wire voice band captures to produce the Fax TIF images and corresponding signaling information. Fax Decoder/Demodulator is also available through command line.

Another version of this application is, FaxDDT38, designed for decoding IP captures and is a command line or batch file based application. FaxDDT38 converts a PCAP file, the output of packet captures such as from GL’s PacketScan™ or other third party IP capturing tools such as Wireshark, into TIFF-F files containing the fax image. It also provides analysis of T.38 packets, T.30 frames, and general call-flow indicators.”

Mr. Kulkarni further added, “There are enhancements introduced to our existing applications and to name a few: Call Capture and Analysis (CCA), Call Data Records (CDR) , ISDN Analyzer, protocol analyzers and Error Insertion, Capture Dialed Digits and more and the addition of the new applications and the enhancements to the existing applications of the T1 E1 Analyzer product suite enhances significantly the user experience and adds value to the T1 E1 testing needs of the customers.”

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.
