Ericsson ROF131049/1 AXE-10 Telecom System Card / Module

The Ericsson ROF131049/1 is listed by Ericsson AXE-10 parts specialists as the APT SPGA card, a board belonging to the APT side of the Ericsson AXE-10 digital telephone exchange. In the AXE-10 architecture, the APT (the exchange’s traffic-handling half, as distinct from the APZ control computer) is the subsystem responsible for call switching and for customer line and junction/trunk access, and cards carrying the APT designation are fitted within this part of the exchange’s GEM subracks. The specific internal function of the SPGA circuit is not published in available documentation, so this listing describes its confirmed subsystem role rather than a detailed circuit-level function. It is supplied as a tested, second-user spare for engineers maintaining an existing AXE-10 exchange. Tech-Star (UK-based, shipped worldwide) stocks this and other legacy Ericsson AXE-10 cards; get in touch to check current stock and confirm compatibility with your installation.
