EANTC Selects Adax for Comprehensive Voice over Broadband Emulator; Costs to Verify Broadband Loop Emulation Services -BLES- and V5.x Voice Gateways Greatly Reduced.Business Editors/High-Tech Writers 3GSM World Congress CANNES, France--(BUSINESS WIRE)--Feb. 19, 2003 Adax, the industry leader in high performance communications and signaling infrastructure, has been chosen by the European Advanced Networking Test Center (EANTC EANTC European Advanced Networking Test Center ) to provide the foundation for its Voice over Broadband (VoB) emulator. The emulator from EANTC, a leading European provider of test and certification services, allows vendors and users of voice gateways to verify standards compliance and performance of access devices without incurring the cost of a large test bed. In addition, further savings are made because the emulated Integrated Access Devices (IADs) are managed by one common user interface, greatly reducing testing time. Adax's ACT4-PCI communications card provides the network interface and V5.x link layer software for the VoB emulator. With this solid foundation, the emulator is able to monitor a high signalling load and simulate both IADs and Local Exchanges (LEs) in a fully integrated, highly intuitive test environment. Adax's ACT4-PCI card provided EANTC with an easy to implement and cost-effective solution. The VoB emulator verifies Voice over DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary networks and gateways. Features include the test of signaling protocol It is a protocol used to identify signaling encapsulation. Signaling is used to identify the state of connection between telephones or VOIP terminals ( IP telephone or PCs or VoWLAN units ). List of signaling protocols:
"Voice over DSL network emulation Network emulation is a technique where the properties of an existing, planned and/or non-ideal network are simulated in order assess performance, predict the impact of change, or otherwise optimize technology decision-making. for IADs and LEs is important for both vendors and users of voice gateways," said Carsten Rossenhoevel, Managing Director Research & Manufacturer Testing, EANTC. "Adax's cost-effective, high-performance, ACT board was crucial in enabling us to bring the VoB emulator to market rapidly providing us, and our customers, with a commercial advantage. The high port density enables our customers to test full 16-link V5.2 interfaces." "EANTC's design team integrated our ACT board into the VoB emulator quickly and easily," commented Robin Kent, Director of European Operations, Adax. "This powerful tool is going to really help people with testing Voice over DSL Networks and Gateways, and we look forward to enhancing it further with EANTC." The ACT4-PCI is a four port fully channelised HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. board, with high-impedance ports for non-intrusive passive network monitoring The term network monitoring describes the use of a system that constantly monitors a computer network for slow or failing systems and that notifies the network administrator in case of outages via email, pager or other alarms. and one of the highest port densities in the industry. The ACT card can handle multiple protocols including X.25, frame relay, LAPB LAPB - Link Access Protocol Balanced , LAPD 1. LAPD - Link Access Procedure on the D channel. 2. LAPD - Los Angeles Police Department. , HDLC and LAPV5, providing up to 1024 DSOs and increasing cell capacity in a single system. This powerful functionality makes the ACT card especially well-suited to the emulator in terms of performance and features but it is also a cost-effective solution, a factor that was very important to EANTC. About Adax Europe Ltd Adax is the industry leader in high performance communications and signaling infrastructure, providing communications controllers and protocol software for existing and next generation networks. Built to meet the demanding signaling needs of packet and circuit switched networks, the Adax products are used for: Signaling and Media Gateways; Gateway and Serving GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. Support Nodes (GGSNs and SGSNs); Base Station Systems (BSS See 802.11. BSS - Block Started by Symbol ) for GPRS networks, SGSNs, Node B and Radio Network Controllers (RNCs) for 3G networks, and Billing and Monitoring Applications.
