Data Connection Enhances DC-Megaco/H.248 Solution

DC-Megaco/H.248 adds support for ITU H.248.1v3, including several new features and enhancements for the Gateway Control Protocol

London, UK: February 5, 2007. Data Connection Limited (DCL), the world's leading independent provider of communications protocol software, has announced enhancements to its DC-Megaco/H.248 solution enabling compliance with the ITU's H.248.1v3 recommendation.

H.248 is an IETF/ITU standards-based signaling protocol that enables media gateway controllers to manage media gateways in establishing media paths in converged networks. It is an essential signaling protocol for gateways, call agents/softswitches, media controllers, media servers, and other voice/data platforms. The H.248 protocol is also utilized in IP Multimedia Subsystem (IMS) environments.

Version 3 of H.248.1 adds new diagnostic capabilities, such as stream level statistics, which enhance the user's ability to monitor and troubleshoot H.248 sessions. A new message segmentation package is also available, which greatly simplifies the transmission of large packets over transports that do not support message segmentation such as the commonly used User Datagram Protocol (UDP).

DC-Megaco/H.248 is a complete package of portable source code, reference and test applications, and customization tools. This package greatly reduces a system vendor's time to market, engineering cost and risk for developing multimedia components of wireline, wireless and IMS solutions. The DC-Megaco/H.248 solution is implemented as libraries and is pre-ported to all the leading operating systems, allowing easy and fast integration to any system architecture.
