•MicroTCA Module Handles. Using the same handles as those used for mezzanine card modules in the AdvancedMC installations provides for consistent form, fit, and function throughout an installation or an organization.

•MicroTCA Light Pipes. The light pipes provide an indication of the operating status of the module, allowing for quick and easy identification and hot-swapping of modules during system use, without risk of shorting or equipment damage.

Status of PICMG Applications in Today’s Telecom Industry.

Although awareness and acceptance of the PICMG standards have grown steadily, implementation of each standard has followed the needs of the marketplace. While the AdvancedTCA concept was the first to be introduced, the AdvancedMC applications might soon outnumber AdvancedTCA applications in terms of number of units implemented and the amount of hardware sold. This is due, in part, to the nature of each application.

AdvancedTCA installations are geared toward the core of the network, so the majority of use is being seen in new (i.e. wireless) applications as opposed to extensive retrofitting of legacy applications. On the other hand, AdvancedMC applications, which provide greater flexibility for applications at the edge of the network, offer opportunities for faster growth in the near future.

However, while recognition and acceptance of the standards continue to grow, there are still some practical considerations to take into account in terms of physical implementation. One of those is that even within the standards, there can be dimensional variations that affect the relationship between a specific handle and a specific microswitch mounting style. For this reason, it pays to evaluate all facets of fit and functionality carefully in the early stages of system design. An experienced hardware provider can help you match appropriate handles and microswitches to ensure smooth operation.
