DCOSS provides carriers and other operators with the ability to test virtually all elements of their networks. In addition, it provides a user-friendly GUI, remote client access (GUI, CLI, SDK), and scripting with which users can capture the performance of networks in a wide variety of scenarios
Gaithersburg, MD, USA (Vocus) June 10, 2010
GL Communications Inc., announced today the release of its enhanced Digital Central Office Switch Simulator (DCOSS) hardware and software. Speaking to media, Mr. Robert Bichefsky, Senior Manager at GL, said, “The DCOSS is a high density switch and a comprehensive traffic generator which supports large volumes of any traffic including voice, fax, modem, and tones. Unique applications of the DCOSS include Lawful Interception, Automated Attendant, IVR Testing, Gateway/ATA modem and fax testing, and SS7 Network simulation. For instance, being a self-contained system with capabilities to easily communicate with external networks, the DCOSS can support an entire SS7 network including LNP, GTT, internal traffic and external phones. Routing and hunt groups are fully supported and configurable”.
He added, “DCOSS is ideal for simulating and testing advanced telecom networks/products including switches, gateways, and transmission systems. DCOSS is a central office switch with both T1 and E1 trunks along with analog and BRI ISDN phone interfaces. DCOSS supports a multitude of protocols including SS7 (SSP/STP/SCP), PRI ISDN (all variants) and CAS (MFC-R2, E1 CAS, and T1 CAS). The DCOSS CAS State Machine provides the versatility of a user-defined script for simulating custom CAS protocols”.
Mr. Bichefsky further added, “DCOSS provides carriers and other operators with the ability to test virtually all elements of their networks. In addition, it provides a user-friendly GUI, remote client access (GUI, CLI, SDK), and scripting with which users can capture the performance of networks in a wide variety of scenarios”.
New Features & Enhancements Introduced in Latest DCOSS version:
•New DCOSS T1/E1 Hardware
The DCOSS has been enhanced to support the latest T1/E1 hardware. The latest DCOSS provides backwards compatibility for the previous versions of T1/E1 hardware as well. And it supports only Windows XP operating system.
Several new enhancements have been added to the DCOSS Remote for additional flexibility when using the remote Client. This includes send/record individual traffic (voice files, digits, tones, fax), access to the SS7 Link Status and increased status of the DCOSS Bulk Calling.
•SS7 Enhanced Support
From the DCOSS GUI or the Remote Client, the individual SS7 Signaling Links can be enabled and disabled. This provides added flexibility when testing the SS7 network.
•Bulk Call Scripting
In order to provide greater flexibility and communication within a running Bulk Call script, the DCOSS can send user-defined events between two scripts. The user-defined events allow for proper synchronization and positive feedback between the two sides of a call.
•CAS State Machine
The DCOSS supports auto start of the CAS State Machine script after loading the T1/E1 trunks.
The latest T1/E1 boards provide full fax capability without additional hardware. In other words, there is now a software option to provide minimum fax or full fax on all boards within the DCOSS (not board specific) when using the latest T1/E1 hardware.
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 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
