One of the foremost global communications equipment providers needed a high-reliability interface board in order to upgrade submarine cable power feed equipment (PFE) installations in the field, and to provide access to their new Network Management System.
LeoTel Software Systems ported and upgraded the VxWorks and Zinc-based embedded software for the later PFE targets, and provided the full software implementation and Windows Embedded image for a rugged embedded Computer-on-Module (COM) interface board in order to extend the feature-set of earlier revisions.
LeoTel worked in partnership with the client’s senior engineers in order to define the requirements for the system and the Computer-on-Module integration with the existing backplane and external interfaces, prior to completion of the full development process and handover.
A rugged embedded Computer-on-Module was chosen for the highly-optimised processing power and the low profile required to fit into the existing PFE shelf. The temperature profile of the board was established early on in the project to ensure that the extreme temperature operating requirements in the field would be met.
Windows Embedded was selected as a suitable embedded environment with a long support lifetime. Windows services, C++ and the boost libraries, supported a consistent memory and fault management strategy, and to enable the board to run for prolonged periods without maintenance, while allowing future upgrades to the feature-set with minimal interference to the software.
