Lindenbaum's Sophisticated Media Resource Function (MRF) Based on MicroTCA


The Lindenbaum Media Resource Function (MRF) is a flexible and energy-efficient carrier-grade MRF-platform based on MicroTCA technology. It is designed for IP Multimedia Subsystem (IMS) architecture and for Next-generation Networks (NGN), with a built-in PSTN gateway to ensure the smooth integration of legacy networks. The MRF is an ideal choice for voice and conferencing applications. Lindenbaum has enriched its product portfolio with this secure, scalable and sustainable “green” MRF solution.

Karlsruhe, Germany, July 19, 2012 --(PR.com)-- The Lindenbaum Media Resource Function (MRF) is a powerful, high-capacity, carrier-grade MRF-platform for cost-effective voice and conferencing solutions in Next-generation Networks (NGN). The IP-based open communication architecture ensures a perfect fit with IP Multimedia Subsystem (IMS) architecture, allowing seamless integration with packet-based access networks and supporting legacy PSTN networks using an optional integrated gateway. Redundant components eliminate single points of failure throughout the system. Several MRFs may be installed at different locations, for efficient geo-distributed solutions. This powerful MRF and PSTN gateway provide various application development interfaces that allow for the rapid development of new voice and conferencing services.

As an expert in innovative conferencing and media solutions, Lindenbaum is proud to add to its portfolio with its new MRF. Based on MicroTCA, that offers flexibility, scalability, easy maintenance, redundancy, high bandwidth capability and security. Lindenbaum is going green to create sustainable concepts: MicroTCA enables true “green” applications thanks to energy efficiency and flexibility, especially compared to other form factors (e.g. CompactPCI, AdvancedTCA). The power consumption in a Lindenbaum MRF can be as low as 0.03 watts per voice line (600 W/20,000 voice lines).

The “intelligent Time-Division Multiplexing” standard (iTDM) takes advantage of the integrated TDM gateway. The primary benefits of iTDM are that it exists as a chassis-optimized, fabric-neutral, multi-vendor supported technology. Within the iTDM standard several TDM channels are multiplexed together into one package, so that there is no need to wait for multiple frame times to accumulate enough data for a given TDM channel.

Within the Lindenbaum Media Resource Function NAT AMCs provide TDM interfaces and iTDM interworking. The MRF is managed by a NAT MicroTCA Carrier Hub (MCH) containing a 16 port GbE switch. It distributes clock signals, manages remote access and inventory. The MCH is responsible for electronic keying and redundancy on the lower layer. It generates system alarms and harmonizes firmware updates.

For a robust MRF solution, Lindenbaum has opted for Erlang and the Open Telephony Platform (OTP). Erlang is a programming language used to build massively scalable soft real-time systems with high availability requirements. The Open Telephony Platform (OTP) is a set of Erlang libraries and design principles providing middleware to develop these systems. It includes its own distributed database, applications to interface with other languages, debugging and release handling tools [see http://www.erlang.org/]. Release handling in Erlang is upgrading and downgrading between different versions of a release, in a (potentially) running system i.e. new software releases of the media resource function can be deployed without interrupting running services.
