Formed in 1979 at the convergence of Computers, Compatibility, and Communications, 3Com has always been committed to interoperability. 3Com's focus helps them to deliver solutions that reduce cost, speed implementation, and strengthen competitive position. The interoperability lessons of 19th century railroads are clear. So as your company considers the requirements for an IP telephony system, interoperability becomes a required feature. And what could be more natural than to look to 3Com for the advantages of IP telephony solutions. After all, compatibility is 3Com's middle name.

This paper describes how VoIP applications can be easily implemented by AudioCodes’ MP-1xx Analog Media Gateway product line together with the Mediant 2000, AudioCodes’ digital gateway. AudioCodes MP-1xx enables distributed enterprises to provide their employees working from small offices or small branches with direct connections via the IP data network to the corporate headquarters’ PBX. In addition to cost-savings related to the installation and PBX maintenance on each remote location, the MP-1xx also enables unified phone services to all enterprise employees.

Many companies have come to the conclusion that enabling their IT infrastructure with VOIP is a good investment. Today it is necessary to keep costs down. Therefore, getting more value out of the IT infrastructure investment especially makes sense. This paper describes a solution whereby business customers can lower their telephone expenditures, while improving communications between employees (both from the workplace and the home) by using VOIP.

There are thousands of network protocols in active use on the internet. System administrators often need to extract information from particular fields in such protocols without having sufficient information or time to programmatically parse the packets. This paper proposes an active learning framework to perform this extraction in an unknown protocol, in which the user presents the system with a small number of labeled instances. The system then automatically generates an abundance of features and negative examples; it then use a boosting approach for feature selection and classifier combination. The system then displays its results for the user to correct and/or add new examples and iterate.

Industry analysts and vendors alike have been trumpeting the arrival of IP-based telephony using Voice over Internet Protocol (VoIP) and its benefits for quite some time now. There are also a number of issues and concerns that might not make VOIP right for a contact center today. This paper addresses the questions that are designed to help IT managers and directors determine if their organizations can easily achieve benefits from VOIP and how to make VOIP deployment a success, beginning with determining if VOIP is a cost-effective solution for an enterprise, understanding what support enterprise’s VOIP solution will need.

Centralized voice messaging allows an organization to provide messaging services to its associates by managing a small number of larger messaging systems from within today's communication networks rather than operating discrete messaging systems at each geographical - and now virtual - point of presence. The scalability of Avaya Modular Messaging supporting up to 144 ports, 15,000 hours of storage, and 20,000 subscribers, makes it an ideal solution to support the deployment of centralized messaging. In deploying a centralized messaging solution, there are several factors that become more important than when deploying messaging systems for a distributed location. These include integration features, scalability, reliability and fail over, time zone, dial plans, and network provisioning.

This paper presents a joint Sonus Networks/Riverstone Networks local voice switching solution that aims to answer the questions surrounding VoIP and to demonstrate that VoIP not only meets the stringent requirements of the world’s largest carriers, but delivers far more capability than the traditional circuit-switched infrastructure. The Sonus Networks/Riverstone Networks solution provides a fully NEBS-level 3 compliant VoIP architecture that can serve either as a dialup Internet offload solution, or as a full replacement for local switching architectures.

Imagine a communications environment where a central directory server not only knows how to reach an individual's work phone, cell phone, and pager, but also her Instant Messaging (IM) program, e-mail, and PDA. Finally, imagine that phone calls to an unavailable person can be intelligently rerouted to another person or group depending upon a number of interrelated factors such as time of day, whether the called person is scheduled to be in a meeting, or whether one or more of her modes of communication is unreachable. These capabilities aren't some dream of a far-off utopian future, but are available today with remarkable advance in communications: Session Initiation Protocol (SIP).

This white paper describes the requirements imposed on IP networks to support an IP Next-Generation Network (NGN) environment. Carrier-class IP will become a fundamental requirement in the development of IP NGN and associated services. Illustrating how this might occur for a typical traditional service, a scenario is presented in which carrier-class telephony is migrated from traditional circuit switching to IP. Each aspect of carrier-class IP in this migration is discussed to provide for a complete overview.

This paper discusses Data Over Cable Service Interface Specifications (DOCSIS) standards, outlines benefits to migrate to DOCSIS 1.1, and highlights the challenges of a migration to DOCSIS 1.1. It gives the motivation to migrate to DOCSIS 1.1, also covers how a DOCSIS 1.1-enabled system can increase a cable operator’s return on investment (ROI) beyond a DOCSIS 1.0 network. The paper talks about providing access to additional revenue streams, or reduce operational or capital expenditures by using DOCSIS 1.1.

In recent years, cable operators have delivered many new profitable data services to subscribers by upgrading their hybrid fiber-coaxial (HFC) networks. By mid-2003, the total number of cable modem subscribers had grown to more than 27 million worldwide, according to the InStat MDR market research group. The new Cisco 10/100 Ethernet and Gigabit Ethernet ML-Series line cards, running the proven, feature-rich Cisco IOS Software, are delivering packet multiplexing and quality of service (QoS) features on the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP).
