MontaVista Rolls Out 3.1 Release of Linux Carrier Grade Edition

10/14/2003 - MontaVista Software Inc., the company powering the embedded revolution, announced MontaVista® Linux® Carrier Grade Edition 3.1 (CGE), the next generation of the company’s carrier-grade Linux operating system and development environment.

MontaVista Linux Carrier Grade Edition 3.1 advances earlier versions of CGE with support for key emerging industry standards designed for high availability and telecommunications. It also adds support for the IBM PowerPC architecture. CGE 3.1 will be the first Linux operating system to combine full support for the PICMG 3.0 Advanced Telecommunications Computing Architecture (AdvancedTCA®) technology with support for key high availability APIs from the Service Availability (SA) Forum. CGE 3.1 is the first Linux operating system to begin implementing APIs from the SA Forum’s Application Interface Specification (AIS) for clustering. Other highlights of the new product are increased support for standards including a Native POSIX Thread Library (NPTL). The third release of MontaVista Linux Carrier Grade Edition also boasts an expanding ecosystem and growing customer adoption.

CGE 3.1 is a carrier-grade quality Linux distribution targeted for edge and core telecommunications including applications for the converging IP and voice networks such as soft switches, SGSN(1) and GGSN(2) and Voice over IP (VoIP) gateways, and many other applications. CGE 3.1 enhances standard Linux with additional real-time, high availability and high reliability features based on the Open Source Development Lab (OSDL) Carrier Grade Linux Specification, and it is designed for deployment in any carrier-grade class environment.

“With a rapidly growing number of major design wins including leading equipment providers such as Alcatel, Iskratel and NEC, MontaVista Linux Carrier Grade Edition has gained strong acceptance in telecommunications. CGE is also being deployed beyond traditional telecommunications applications in areas such as equipment testing and airport ground services by leading companies such as Agilent and CNS Systems,” said Glenn Seiler, director of Product Marketing, MontaVista Software. “CGE addresses the needs of telecommunications equipment manufacturers (TEMs) and networking equipment providers (NEPs), enabling them to meet ever-increasing time-to-market pressures by lowering their cost and accelerating time to deployment.”

Key Features
CGE 3.1 adds many important features to the already rich Carrier Grade Edition product line. New features include Persistent Device Naming (guaranteeing consistent device naming), SysFS – a standard device driver interface model that supports Persistent Device Naming, and NPTL support for improved compliance and scalability for POSIX threads. CGE is also certified on Oracle 9i, Release 2. CGE builds on key new technologies introduced with the previous release (Version 3.0), some of which are only available from MontaVista, such as online debugging (MontaVista Field Safe Application Debugger) and patching of deployed applications (MontaVista Runtime Application Patcher). MontaVista, a significant contributor to open source, has also contributed high availability features including the OpenIPMI project and CompactPCI Hot Swap subsystem. CGE 3.1 now supports more than a dozen reference boards including both Intel Architecture and PowerPC boards from vendors like Force Computers, IBM, Intel, Motorola and RadiSys.

Growing Customer Adoption
Earlier this year, Alcatel signed a major multi-year corporate contract with MontaVista Software for CGE, making it a key building block for Alcatel products with embedded or real-time constraints. (Read the joint Alcatel-MontaVista announcement at

NEC recently launched a new NEC Advanced-TCATM telecommunications platform for mobile operators using CGE. “We believe that MontaVista Linux is one of the most powerful Linux development platforms available today and we are giving our customers the best foundation one can think of to realize their product features,” explained Mr. Takatoshi Numasato, senior general manager of the Mobile Network Operation Unit at NEC “CGE 3.1 will reduce development time and costs for telecommunications and networking equipment providers. It will also allow telecom carriers to provide rich services to their customers promptly, with carrier-grade reliability, easy operation and high performance.”

CGE also has played a key role for Iskratel, a provider of integrated telecommunication solutions in Europe. “Iskratel has been able to launch new and advanced telecommunications products consistent with the needs of our customers," said Franc Dolenc, director of Iskratel Business Unit Wireline. "By using a modern OS such as CGE, we can provide our customers with a low-risk and cost-effective product platform supporting carrier grade services."

CGE is the chosen operating system for the data management and monitoring and control subsystems in the new VDL 4000/GS I ground station from C.N.S. Systems AB in Sweden. “MontaVista Linux Carrier Grade Edition provided us with a robust and stable platform and enabled us to get to market in an extremely short time period, ” said Tommy Bergström, chief technology officer, C.N.S. Systems. “We also appreciated MontaVista Software’s great regional support and the fact that CGE has been validated to work seamlessly with our chosen hardware platform.”

MontaVista Linux Carrier Grade Edition is fully compliant with the current Open Source Development Lab Carrier Grade Linux Specification 1.1, and the company will work to ensure future product compliance with OSDL Carrier Grade Linux Requirements Definition 2.0, announced recently. CGE 3.1 also supports open modular communications standards such as Advanced TCATM 3.x from the PCI Industrial Computer Manufacturers Group (PICMG). CGE 3.1 is the first Linux operating system to comply with key APIs from the SA Forum Application Interface Specification (AIS). They include the AIS CLM (Cluster Membership) API that provides a mechanism for applications to determine members of a cluster and track membership changes. The AIS AMF (Availability Management Framework) API provides a mechanism for applications to register with the cluster executive. CGE 3.1 will implement an Application Heartbeat that complies with the AIS AMF specification.

“Once again, MontaVista Software is taking the lead in delivering high availability open source software solutions that are compatible with industry standards,” said Timo Jokiaho, president of the Service Availability Forum. “MontaVista Software continues to provide vision and guidance as well as real products to enhance Linux to meet the needs of the telecommunications market segments.”

MontaVista Linux Carrier Grade Edition 3.1 will be available in the fourth quarter of this year. For more product information and highlights of the key new features in CGE 3.1, please visit Additionally, visit the MontaVista Technology Highlights Web page at
