COM Express
This popular standard continues to be updated as improvements and changes to silicon continue. The subcommittee has been focused on support for four 10 G KR interfaces with a new Type 7 pinout. Discussions have revolved around the total number of signals to support the 10 G channels, including interfaces for PHY configuration, LEDs, and [...]

Hardware Platform Management
The Hardware Platform Management (HPM) subcommittee started work in January 2015 with a focus on enabling the PICMG HPM layer for Internet Protocol version 6 (IPv6). See the article “Adding IoT friendliness to AdvancedTCA and related specifications” in the Winter 2015 issue of PICMG Systems and Technology for background on the history and importance of [...]

Physics activities
The Physics community that developed ATCA 3.8 rear transition module (RTM) extension and MTCA.4 with µRTM is very close to issuing a set of new hardware extensions, called MTCA.4.1, which introduce an additional rear backplane to support both precision analog and digital functions. The backplane supports ancillary rear power modules that can deliver positive and [...]

MicroTCA and the Advanced Mezzanine Card (AMC)
The “Higher Speed Ethernet Fabrics for MicroTCA.0 and AMC.1” group is working on bringing 40 GbE to MicroTCA systems. The committee is currently working on completing signal-integrity studies across the full interconnect channel. S-parameter models for the backplane and AMC have been developed and simulated; work on the MCH is being completed. Combinations of 90 [...]

Where does xTCA fit in SDN?
It’s widely known throughout the carrier world that there is an alarming trend in the ARPU, as well as cost per bit. This has driven a significant interest in the carrier world in Software-Defined Networking (SDN), which separates the control and data planes in network switches. At the first day of AdvancedTCA Summit 2012, many of the presentations – and much of the hall talk – was centered around OpenFlow, the preeminent SDN specification, and how it can/may be used in future carrier network architectures.
