Ericsson ROJ20407/1 AXE10 Telecom System Card / Module

The Ericsson ROJ20407/1 is an IO2B input/output board used within Ericsson’s AXE-10 digital switching platform, documented as a 16-port I/O module. It fits into a standard Ericsson AXE-10 magazine alongside related regional processor and control boards, providing input/output interfacing between the exchange’s processing hardware and the wider switch. As with other ROJ-prefixed AXE-10 system cards, it communicates with the rest of the exchange via the magazine’s internal backplane and is not intended as a standalone device. AXE-10 exchanges built on this hardware generation remain in service in a number of legacy fixed and mobile networks, and operators continue to maintain them with tested used parts as new-build stock is no longer available from the original manufacturer. Tech-Star supplies the ROJ20407/1 as a tested pull from decommissioned AXE-10 equipment, suitable for engineers who need a working replacement card, a hot spare, or stock to support an ongoing maintenance contract.
