Tdsoft Announces Standard Based ELCP Signaling Stack Software Between VoDSL Gateways and IADs.Business Editors/High-Tech Writers CeBIT 2001 HANNOVER, Germany--(BUSINESS WIRE)--March 22, 2001 Allows Carriers to Chose Best-of-Breed VoDSL Equipment and Speed Up Interoperability Following its successful Voice over Next Generation Access (VoNGA) program, Tdsoft, the leading provider of Voice over Next Generation Access solutions, today announced the first standards-based ELCP ELCP Emulated Loop Control Protocol ELCP Extended Linear Complementarity Problem Signaling Stack software between VoDSL Gateways and IADs (Integrated Access Devices). In order to promote the deployment of Voice over ATM 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 service, enable carriers to choose best-of-breed equipment based on open solutions, and to speed up interoperability, the ATM Forum specified in June 2000 the ELCP protocol in a standard that outlines voice transport Over ATM (Broadband Loop Emulation Service, BLES BLES Broadband Loop Emulation Service (DSLF) BLES Buffer Layer Engineering in Semiconductors (ESPRIT Project 6854) ) using AAL (ATM Adaption Layer) The part of the ATM protocol that breaks up application packets into 48-byte payloads which become ATM cells when the 5-byte headers are attached. The AAL resides between the higher layer transport protocols and the ATM layer. 2 signaling. ELCP (Emulated Loop Control Protocol) is a message-based protocol that relies on the ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe. V5.2 standard. This protocol specifies the mechanism where V5.2-based signalling messages are exchanged between the VoDSL Gateway and IAD to support both POTS (Plain Old Telephone System) and ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. voice over ATM. The major advantages offered by ELCP, such as open standard, concentration and dynamic bandwidth allocation Dynamic Bandwidth Allocation (DBA) is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth. capabilities, POTS and ISDN over ATM, ATM Forum LES-MIB for integrated standards-based management support, support for National parameters and reliable connectivity between the VoDSL Gateway and IAD, make this the signaling protocol of choice for Carriers who are deploying robust and feature-rich Voice over DSL services to their business and residential customers. "The extensive experience with V5 software, protocol converters and switch simulators, places Tdsoft as the best vendor to bring an advanced standard ELCP signaling stack," said Ezra Mizrahi Marketing Director of Tdsoft. "ELCP will allow IAD, IAD reference design, IAD on a chip and network processors vendors to build a flexible design platform that supports seamless interoperability with leading voice gateway vendors, which should in turn further simplify the product development process, increase interoperability at the IAD product development stage and reduce the time to market for a fully interoperable end-to-end VoDSL solution," adds Mr. Mizrahi.
