Traffic generation, over established voice calls, provides quality measurement results for VOIP Networks, Wireless Networks, PSTN, ATM Networks, and all switch types that utilize T1 E1 circuits.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, announced today enhanced Traffic Generation using its Digital Central Office Switch Simulator (DCOSS).

Speaking to media persons, Mr. Robert Bichefsky Senior Manager of the company for Product Development said, “Generating telecommunications traffic is one of the essential elements of a quality Central Office Simulation tool. Traffic generation, over established voice calls, provides quality measurement results for VOIP Networks, Wireless Networks, PSTN, ATM Networks, and all switch types that utilize T1 E1 circuits.”

He added, “DCOSS provides two methods of generating traffic. External traffic generation implies that analog/digital phones, fax machines, and modems be connected directly to the DCOSS for both generating calls as well as terminating calls. DCOSS can accept up to 64 analog phones and/or 16 BRI channels. Internal traffic generation is accomplished using the onboard DCOSS DSP resources.”

“Voice Files (PCM a-Law, PCM u-Law, WAV), DTMF/MF Digits, Single/Dual-Frequency Tones, Faxes, and Modem traffic can be simulated over the established calls. The user can configure the DCOSS to generate various types of traffic over multiple timeslots/trunks.”

“High-density traffic generation is very common during telecom testing. Using the DCOSS, up to 16 digital T1/E1 trunks can be configured, simultaneously, for sending a variety of traffic, which in essence will simulate real world scenarios.”

Mr. Bichefsky further added, “DCOSS provides Quality Assessment tools for the internal/external generated traffic. Modem traffic (text files) and received Fax files are quality tested using methods to determine if the data received coincides with the original data sent. DTMF/MF Digits and Frequency Tones are quality tested using digit and tone detectors. Voice Files are quality tested using VQT algorithms. These algorithms include PAMS (ITU P.800), PSQM/PSQM+(ITU P.861), and PESQ (ITU P.862).”

Main Features:

·Modem Traffic Generation (V.21, V.23, V.34, V.90, V.92) with up to 96 simultaneous calls. Send/Receive text files with verification of information (MQT). Display modem terminals for manual modem traffic generation.

·Fax Generation using V.27, V.29, V.33, V.17 protocols with up to 480 simultaneous calls. Multiple page documents allowed with verification of information (FQT).

·Voice Files (in 8-bit a-law & µ-law, 16-bit raw & WAV file formats) Generated/Recorded using PCM a-Law, PCM u-Law, WAV file types with up to 480 simultaneous calls. Send Files continuously. Recorded file verification using PAMS, PSQM, PSQM+, PESQ algorithms. A-Law to u-Law auto conversion.

·Send/Detect DTMF/MF Digits simultaneously over 480 established calls. Auto-send digits when call is established.

·Send/Detect Single or Dual Frequency Tones simultaneously over 480 established calls. Auto-send tones when call is established. Send tones continuously.

·Call Quality Criteria with user-defined configuration. Pass/Fail calls based on results from MQT, FQT, VQT, detected digits, detected tones. Additional Statistics and Call Records associated with Call Quality Criteria.

·Traffic Generation using Manual Calls or Automated Bulk Calling. Create Bulk Call configurations fast, incorporating great flexibility and testing power. Optional Bulk Call Scripting allows additional flexibility including conditional statements and loops.
