Ericsson ROJ20403/1 AXE10 / AXE810 Telecom System Card / Module

The Ericsson ROJ20403/1 is an ETC5 board used within Ericsson’s AXE-10/AXE810 digital switching platform. ETC5 cards are fitted into ETM-type magazines inside standard Ericsson BYB 501 switch cabinets, typically alongside related boards such as the DLHB and RP4-H, with multiple ETC5 units installed per magazine as part of the exchange’s core switching and control hardware. As with other AXE-10 system cards, the ETC5 plugs into the magazine backplane and communicates with the rest of the exchange over Ericsson’s internal bus architecture. AXE switches built around this hardware family have been deployed worldwide in fixed and mobile telephone exchanges, and remain in service in many legacy networks today. Tech-Star supplies the ROJ20403/1 as a tested pull from decommissioned AXE equipment, suitable for engineers maintaining existing AXE-10/AXE810 installations who need a replacement card, hot spare, or stock for a maintenance contract.
