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 Signaling Bits Recorder/Analyzer software which records all signaling bit changes along with the time-stamped indications for each bit.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”The time-stamp clock starts from zero and then continues by displaying the elapsed time-period for each bit in ‘ms’. The same application can also provide time stamped indications of all extra bit changes for E1 systems in Data Display. The signaling transitions may be transmitted using Transmit Signaling Bits, Transmit Multiframe, Transmit Gaussian Noise, Transmit Tone, or Playback from File applications (available under Intrusive Test and Special Applications menu options).”

He added, “The Display page allows the user to select the type of timestamp that is displayed - Absolute or differential. By default, Absolute time stamping is enabled and Differential time stamping is disabled. In case of Differential time stamping, the time elapsed since the last transition is displayed. In Absolute time stamping, the application displays the time elapsed since it started scanning for transitions. The user has the option to select Device and Timeslots using Device and Timeslot selection options respectively. These features can be accessed using the ‘Options’ control as shown in the screenshot to the below. Users can select one or more devices with 1-31 timeslots for E1 and 0-23 timeslots for T1.”

Mr. Kulkarni further added, “Data display option only for (E1) provides two types of data display options, namely Signaling Bits and Extra Bits. Extra Bits- displays 3 bits, which are defined as bit positions 5, 7, and 8 of timeslot 16 of frame -0 in the CAS framing format only. The E1 software can configure these bits.

Signaling Bits- The signaling bits associated with each timeslot are displayed in real-time. This application should be used in CAS mode only. The signaling bits A, B, C, and D are displayed for all channels. These bits are demultiplexed from timeslot 16."

Important Features:

·Continuous full-duplex recording of signaling bits for any or all channels for any length of time
·Permits detailed analysis of recorded signaling bits for any channel
·Applications include call duration, wink analysis, abnormal terminations, call setup, etc.
·Live T1/E1 signal is not disturbed
·Recording can continue for extended periods of time
·Recording can be terminated at any time manually
·User has the choice of recording the data from selected channels or from all the channels

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

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.
