Aztek Engineering Announces First Protocol Software Solution for New ETSI V5 Second Edition Standards.BOULDER, Colo.--(BUSINESS WIRE)--June 29, 1999-- New Protocol Software Provides Access Network Vendors With Compatibility Between Existing 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 Standards and Future ETSI V5 Second Edition Specifications Aztek Engineering, Inc., an international provider of software and hardware for the telecommunications industry, today announced the availability of the industry's first V5 Second Edition compatible software product, AV5 Release 3.0 with the Second Edition Module. The new software provides a complete interface solution for the new European Telecommunications Standards Institute (body) European Telecommunications Standards Institute - (ETSI) A European version of the ITU-T(?).

"The Second Edition of the ETSI V5 standard poses a variety of compatibility challenges for the access network equipment manufacturer," says John Farnbach, vice president of marketing for Aztek Engineering. "Aztek's new AV5 software products will provide access network customers with a flexible, future-proof solution to manage the array of compatibility issues that are imminent with the release of the new V5 Second Edition standards." As an associate member of the ETSI since 1996, Aztek participated in the creation of the ETSI V5 Second Edition specification. With Aztek's AV5 Release 3.0 and Second Edition Module, access network vendors are provided with the first complete solution for compatibility between both V5 First Edition and V5 Second Edition standards. The new AV5 software effectively bridges compatibility between newly introduced switch equipment and older systems still operating with original V5 standards. By integrating Aztek's modular, customizable and proven AV5 real-time software, access network vendors save time and money, and remain focused on system designs that expand carrier options for purchasing access network and local exchange equipment. The V5 Standard and the Second Edition In 1994, the ETSI published an open digital interface standard for access network systems in local exchanges. The resulting European standards, V5.1 and V5.2(Footnote No. 5), were rapidly adopted by the ITU as worldwide standards. A growing number of operating companies operating company A business that engages in transactions with outsiders. and telephone administrations in Europe, Asia, Africa and Latin America Latin America, the Spanish-speaking, Portuguese-speaking, and French-speaking countries (except Canada) of North America, South America, Central America, and the West Indies. now mandate the V5 protocol as part of any newly deployed local exchanges or access network systems. In 1999, ETSI will publish the Second Edition for the V5.1 and V5.2 standards to improve robustness and efficiency and also to eliminate ambiguities. The ETSI V5 Second Edition, relative to the original V5 specification, provides: - Improved robustness in the startup of a V5 interface. In particular, it defines how protection switching is supported during a V5 interface startup. - Improves the accelerated port unblocking process and adds an accelerated port blocking process. - Significantly improves the efficiency of periodic pulse metering. - Adds timers on the variant and interface ID checking process. - Clarifies ambiguities in the original specification. Access Network Challenge Telecommunications carriers have historically placed the responsibility for interoperability The capability of two or more hardware devices or two or more software routines to work harmoniously together. For example, in an Ethernet network, display adapters, hubs, switches and routers from different vendors must conform to the Ethernet standard and interoperate with each other. between the access network and local exchange on access network equipment manufacturers. Now with the advent of the ETSI Second Edition, access network vendors are additionally faced with the interoperability challenge between first and second edition switches. These new V5 standards are expected to be deployed beginning in mid-1999. Second Edition and original V5 will coexist co·ex·ist intr.v. co·ex·ist·ed, co·ex·ist·ing, co·ex·ists 1.

To face the broad responsibility for interoperability the access network vendor needs an adaptable, future-proof V5 solution. Aztek's AV5 Second Edition Module's Benefits and Advantages to Access Network Suppliers The following capabilities are supported by AV5 with the Second Edition module: - First and second edition behavior can be set with provisioning flags, independently for each V5 interface. - Enables an AN to simultaneously interface correctly (meeting ETSI requirements) with both first and second edition switches. - Future-proofs the AN: When a switch is upgraded to second edition, the AN can simply re-provision the V5 interfaces for second edition. - Solves the problem of first/second edition incompatibility The inability of a Husband and Wife to cohabit in a marital relationship. incompatibility n. the state of a marriage in which the spouses no longer have the mutual desire to live together and/or stay married, and is thus a ground for divorce . - Continues the capabilities established with AV5's provisionable V5.1 or V5.2 behavior. - AV5 supports up to 256 V5 interfaces. Each can be provisioned independently as V5.1 or V5.2 and as first or second edition. Aztek's AV5 software meets all applicable ETSI requirements, is hardware independent and designed for maintainability. The product is scaleable for different size installations and is processor and memory efficient. In addition, the AV5 platform is portable to a variety of real-time operating systems (operating system) Real-Time Operating System - (RTOS) Any operating system where interrupts are guaranteed to be handled within a certain specified maximum time, thereby making it suitable for control of hardware in embedded systems and other time-critical applications. and microprocessors. Aztek's AV5 products offer a unique processor redundancy option that supports redundant CPUs for systems where high availability Also called "RAS" (reliability, availability, serviceability) or "fault resilient," it refers to a multiprocessing system that can quickly recover from a failure.
