T1 E1 Call Capture & Analysis

The Call Capture and Analysis (CCA) application is used to initiate recording of calls, either automatically or manually directly from T1 E1 and/or 2-wire lines.

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 T1 E1 Call Capture & Analysis software product.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”The Call Capture and Analysis (CCA) application is used to initiate recording of calls, either automatically or manually directly from T1 E1 and/or 2-wire lines. The application uses GL's USB Portable T1 E1 Analyzer Units or Universal HD T1 E1 Analyzer Cards to interface non-intrusively with T1 or E1 lines.”

He added, “Automatic call capturing can be triggered from both directions (east and west) of transmission. The call capture application supports following types of triggers for auto capturing of call:
·Signaling based triggers - CAS -R1, wink start, MFC-R2
·ISDN and SS7 message based triggers
·Traffic activated triggers: Voice based on a minimum power level, Tones of specified frequency - Ring back tone, Dial tone, Busy tone, and DTMF digits, Fax traffic - V.32 / V.17, V.27, V.29, Modem traffic - V.22 forward/reverse channel, V.34 & V.90 uplink, Binary V.90 downlink, FSK, Any type of signal based on any power level

Subsequently, captured calls can be played back and analyzed in time and spectral modes using a commercial sound card, built-in high fidelity speakers, and audio viewing software (Adobe Audition, Goldwave).”

Mr. Kulkarni further added, “Frequency, power of east and west directions cannot be shown in real time in CCA application. The application can only capture the files. The application also indicates the channels on which a recording is taking place and the files names to which data is being stored. Scanning mode is possible wherein all 24 or 30 channels are scanned for call initiation and recording. A message area provides status of the capture process.”

Important Features:
·Automatic or manual initiation of call recording.
·Real-time display of signaling bits for all channels in both directions.
·'Scan' or 'Channel' mode for call initiation detection and capture.
·User specified record time.
·Automatic termination of recording, or Manual termination.
·PCM data captured to two synchronized disk files (east and west directions) for post processing.
·All call data are captured including signaling bits, voiceband data, signaling protocol data (e.g. DTMF or MF digits), various types of traffic such as fax, modem, voice, and any type of signal.
·Unlike the other traffic options, triggering on voice traffic can be fine-tuned to the power level of the voice data.
·Voice power level can be set to filter out weak or undesirable voice data.
·ISDN calls recorded with CRV, ISDN message type, channel, direction, called and calling numbers. ISDN calls can be captured with customized called and calling number filter.
·Enhanced application includes call capture based on SS7 signaling messages, and the ability to set triggering to capture calls when any SS7 signaling messages are received.
·"Call filtering" feature is used to capture calls with a user-defined called and calling numbers rather than all calls.
·Various File naming conventions based on the type of capture. The file naming conventions suit various types of capture applications such as MFC-R2, signaling, ISDN capture, manual capture etc.
·Different Encoding formats supported, including automatic conversion of u-law and A-law PCM files to WAV file format if required.
·The digit parsing feature of CCA application helps user to distinguish CAS R1 or MFC-R2 calls by prefixing called or calling numbers to the filename.
·Capability of capturing on a single direction, East or West side in a dual card system.
·Supports logging of call summary records, facility alarms, and supervisory signals in CSV or binary file formats.
·Provides an option of stamping the captured files sequentially or with date/time.

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.
