DCOSS Simulation System is a single platform system that supports traffic and signaling testing of TDM, VoIP, 2-Wire, and BRI networks. Large volumes of traffic of any type can be simulated including: voice, fax, modem, tones, and dual tones
Gaithersburg, MD (Vocus) July 29, 2009
GL Communications Inc., announced today the release of Enhanced DCOSS Simulation System. Disclosing the news to the media, Mr. Robert Bichefsky Senior Manager at GL said, “DCOSS Simulation System is a single platform system that supports traffic and signaling testing of TDM, VoIP, 2-Wire, and BRI networks. Large volumes of traffic of any type can be simulated including: voice, fax, modem, tones, and dual tones”. He added, “Signaling flexibility spans from ISDN, SS7, CAS, MFC-R2, SIP, H.323, Loop start, ground start, Fax and Modem signaling, and many many more”.
Mr. Bichefsky, further added, “The main feature of the Digital Central Office Switch Simulator (DCOSS) is the ease with which it can be operated removing the complexity of configuration and signaling setups associated with other simulators. The system can be up and running within minutes creating loads of hundreds to thousands of calls. However simplicity does not preclude complexity. If the user so desires, she (he) can use the inherent power of the DCOSS to create the most complex calling scenario possible”.
Compatibility of DOCSS Simulation System with different network platforms:
The DCOSS supports a variety of different TDM protocols including PRI ISDN, SS7, and CAS. All variants of these protocols are supported. Large T1 E1 networks with traffic can easily be simulated.
2-Wire with APS
The DCOSS with 2 Wire Analog Phone Simulator (APS) can generate/receive analog calls to connect to the PSTN, ATAs, or Gateways. Once the call is established, the APS can send/receive fax, modem, voice files, DTMF/MF digits and Single/Dual Frequency Tones. The APS also supports all supplementary call control features (3-way calling, call forwarding, call transfer).
VoIP with Media Gateway
The DCOSS with a Media Gateway front end provides full support for VoIP protocols including SIP, H.323, Megaco, MGCP, and T.38 fax. Using the DCOSS GUI or remote client, both VoIP and TDM calls can be established manually or automatically (Bulk Calling). Once the call is established a variety of traffic can be generated including fax, modem, voice, digits, and tones.
DCOSS with BRI Subscriber / Network
The DCOSS can connect to BRI Networks as either terminal (BRI phone) or the Network. The DCOSS BRI simulation supports up to 60 BRI terminal phones and up to 16 BRI ST-Interface Network connections. Both the BRI Terminal simulation and the BRI Network simulation supports 1 D-Channel + 2 B-Channels and Automated Bulk Calling with a variety of different traffic (Fax, Modem, Voice File, Digits and Tones). The BRI Terminal simulation also supports all supplementary call control features (3-way calling, call forwarding, call hold, call transfer).
Some of the Important Features
•T1 E1, 2-Wire, Ethernet, and BRI lines and trunks
•Call capacity from hundreds to thousands of calls simultaneously (scalable depending on configuration selected)
•Voice, Fax, Modem, and Tones Generation and Reception
•Remote Access including full support for SDK (great for regression testing)
•Call Monitoring and Recording
•Automatic Bulk Call Generation/Reception for Load Testing
•Bulk Call Scripting
•Call Statistics and Call Detail Records
•Save/Load all parameters as user-defined configurations

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, STM-1, 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, etc.), and with capacities up to thousands of channels.
GL’s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL’s wirelss 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
