Ericsson ROF131330/1 AXE-10 Telecom System Card / Module

The Ericsson ROF131330/1 is a Memory Unit circuit board used within the Ericsson AXE-10 digital telephone exchange platform. The AXE-10 is one of the most widely deployed public switched telephone network (PSTN) switching systems in the world, and memory unit boards such as this one form part of the processor and data-storage subsystem that keeps call-processing software, configuration data and subscriber records accessible to the exchange’s central processors. Boards of this type are typically installed within an AXE-10 magazine alongside regional processors, signalling terminals and other control cards, and are matched to the specific processor architecture and software release running on the exchange. This item is offered as a tested, refurbished spare suitable for maintaining or expanding existing AXE-10 installations where original equipment manufacturer parts are needed. Tech-Star (UK-based, shipped worldwide) stocks a wide range of legacy Ericsson telecom hardware; enquire with your exchange model and software release to confirm compatibility before ordering.
