The Multiplexer/ Demultiplexer software provides the capability to multiplex individual files on different timeslots into one aggregate output file and the reverse process of demultiplex one aggregate file into individual timeslot files.
Gaithersburg, Maryland (PRWEB) July 14, 2012
In Gaithersburg, Maryland, USA, on July 13, 2012, 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 Multiplexing /Demultiplexing Software.
Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “The Multiplexer/ Demultiplexer software provides the capability to multiplex individual files on different timeslots into one aggregate output file and the reverse process of demultiplex one aggregate file into individual timeslot files. The program is applicable to T1 E1 multiplex systems and is a companion software for the files transmit and the files receive programs available with the T1 E1 cards.”
He added, “In Multiplexing process a frame is created with one byte from each input file. Finally the frame is copied to the output file. This process is repeated until all bytes from input files are exhausted. For smaller files once the end of file is reached, bytes are read from the beginning of the file or filler bytes are used for padding. The Demultiplexing process is the reverse process of multiplexing. In case of Demultiplexing bytes from an input file is copied into the output files successively starting from the 1st file to last file. Each time a single byte is copied into a single file.”
Mr. Kulkarni further added, “The Multiplexer/ Demultiplexer software is an accompanying software for the File-transmit & File-receive programs, which accompany the T1 E1 cards. Using the multiplexing feature, files from different time slots can be multiplexed together & sent in the T1 or E1 line. Now the same file can be transmitted back by loop back technique. This is De-multiplexed and resultant files can be compared with the original files to find out any fault in the line and the fault free working of the Multiplexing/De-multiplexing algorithms used.“
·The user enters the output file format for multiplexing, which can be any number of channels from 2 to 24 for T1 or 2 to 32 for E1.
·The user provides the output file names for the demultiplexed outputs. He will be able to select certain timeslots (or all timeslots) for demultiplexing as desired. The user enters the file format of the aggregate input file, which can be any number of channels (timeslots) from 2 to 24 for T1 or 2 to 32 for E1.
·Mux De-mux application supports Multiplexing and De-Multiplexing of files (voice data streams) of different sizes. Its Wrap file feature when checked will enable retransmission of smaller file from beginning till the completion of copying of all the files into the output file. Incase the wrap feature is not checked, the filler bytes (Specified by user/Default Value '00') will be used to fill the gap

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.
