T1 E1 Traffic Classifier

A Tool for Non-intrusive, Real-time Monitoring and Classification of T1 and E1 Traffic.

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 T1 E1 Traffic Classifier - A Tool for Non-intrusive, Real-time Monitoring and Classification of T1 and E1 Traffic.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”It is vital to know, what is happening on T1/E1 network and how optimally the T1/E1 network is being used even though one may be running a gigabit LAN for internal network. But most corporate networks are still connected to the WAN through a T1 or slower connection. This speed mismatch between the internal network and the outside world may lead to a potential data bottleneck, and is an important reason why for any Network Provider or Network Manager to understand and analyze 'what is happening on their T1/E1 line."

He added, “GL's Traffic Classifier can analyze and classify various traffic such as voice, fax, data, tones (dial tone, ring-back tone, busy tone etc) as well as identify dialing digits and other events happening on a T1/E1 network. It uses various identifying schemes depending on the country of choice and classifies the traffic, based on the dialing tones stipulated for that country.”


·Real-time Snapshot: Get a real-time snapshot of your T1/E1 network activity.
·Surveillance and Data Collection: You can monitor all the events on all the timeslots on a single or multiple T1/E1 line. You can also do surveillance for extended periods by recording the classification results for days, weeks or months at a time.
·Equipment Manufactures and Equipment Vendors: Use Traffic Classifier to do pre-deployment analysis of a network so as to provide an optimized solution for your customers.
·R & D, Traffic Engineering and Network Condition Analysis: Traffic Classifier is an ideal tool in an R & D environment for understanding, analyzing and traffic engineering of a T1/E1 network.

Important Features:

·Ability to non-intrusively monitor the traffic on a T1 or E1 line in real-time and offline modes.
·Sixteen traffic types are classified, which include Tones (dial, ring, busy), Voice/Speech, Data and Fax Signaling, Dialing digits (DTMF, MFR1, MFR2F, MFR2B) etc.
·Data and fax modulations such as V.22, V.34, V.29, V.32, and V.27 are supported as traffic types.
·Monitor single or multiple DS0s on multiple T1/E1 lines.
·Monitor the T1/E1 line locally or remotely through TCP/IP connection.
·Provides real-time display of the traffic types for each DS0 on the T1/E1 trunk.
·Result options allow the results to be either displayed on the screen, and/or save it to a file for extended periods.
·Off-line (playback) feature can playback or fast forward previously recorded results.
·Analyzes the T1/E1 traffic and graphically displays the results as a strip-chart.
·Codecs supported - µ-Law, A-law, and linear.
·Traffic view for a particular span of time by using the File Scroller option.
·Four algorithm options (Linear, quadratic, hybrid and hybrid filtered) to fine-tune the classification results.

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) is 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.
