2012-06-01 - N.A.T. provides AMC and MCH cards for Lindenbaum’s sophisticated Media Server based on MicroTCA

The new generation of the Lindenbaum Media Server is based on MicroTCA components supplied by N.A.T..

The Lindenbaum Media Server is a powerful, high-capacity, carrier-grade media platform for cost-effective voice and conferencing solutions. N.A.T. as expert of innovative communication solutions replaced the former standard Compact PCI with MicroTCA due to advantages such as flexibility, scalability, maintenance, redundancy, high bandwidth and security.


The Lindenbaum Media Server is a powerfulhigh-capacitycarrier-grade media platform for cost-effective voice and conferencing solutions. The IP-based open communication architecture allows seamless integration with (growing) packet-based access networks while supporting legacy PSTN networks using an integrated gateway. Thus protecting current investments and offering smooth migration to next-generation IMS-based architectures. Redundant components eliminate single points of failure throughout the system. For geo-distribution media server resources may be utilized at different locations. The complexity of this powerful media server and PSTN gateway is hidden behind multiple application interfaces that allow rapid development of new voice and conferencing services.


N.A.T. as expert of innovative communication solutions replaced the former standard Compact PCI with MicroTCA due to advantages such as flexibility, scalability, maintenance, redundancy, high bandwidth and security. N.A.T. goes beyond these technical features and highlights the aspect of going green to create sustainable concepts: MicroTCA enables this "green" application due to energy efficiency especially compared with other form factors (e.g., cPCI, AdvancedTCA). Additionally, the power consumption in a Lindenbaum media server can be as low as 0,03 Watt per voice line (600 Watt/20,000 voice lines).


By using the I-TDM standard the advantages of an integrated TDM gateway can be leveraged. The primary benefits of the iTDM standard are that it exists as a chassis-optimized, fabric-neutral, multi-vendor supported technology. Within the I-TDM standard several TDM channels together are multiplexed into one packet, so that there is no need to wait for several frame times to accumulate enough data for a given TDM channel. Two options are provided within I-TDM and both options are supported by the Lindenbaum Media Server:
  • Packet emission interval of 125 µs, which provides the lowest possible latency
  • Packet emission interval of 1 ms, which provides higher latency, but is easier to handle in software-centric approaches


Within the Lindenbaum Media Server NAT AMCs provide TDM interfaces and I-TDM interworking:
  • The NAMC-8569-xE1/T1 is a signalling processing engine providing 16 E1/T1/J1 line interfaces including TDM cross connect and I-TDM interworking in full-size form factor.
  • The NAMC-STM1 is a STM-1 SDH line interface card providing add/drop functionality at DS0 and subrate levels including TDM cross connect and I-TDM interworking for termination and monitoring in mid-size form factor.


The Media Server is managed by the NAT-MCH containing a 16 port GbE switch, distributing the clock signals, managing the remote access and the inventory. The NAT-MCH is responsible for electronic keying and redundancy on the lower layer and generates system alarms and harmonizes the firmware updates.
