Ericsson ROF1375291/1 Business Telephone / PBX Systems Telecom System Card / Module

The Ericsson ROF1375291/1 is a CPU (CP-3) processor board used within Ericsson’s business telephone/PBX system hardware. Ericsson’s ROF-prefixed cards of this type are central processing boards, providing the core control and call-processing logic for the exchange or PBX system they are fitted to, in the same product family as other Ericsson CPU cards such as the CPU-D3, CPU-D4 and CPU-D5C used in later PBX generations. The CP-3 fits into a standard Ericsson system cabinet and communicates with the rest of the platform over the internal backplane, coordinating signalling, switching and system management functions. Ericsson business communication systems from this generation remain in service at a number of sites, and engineers continue to maintain them with tested used parts as new stock is no longer produced. Tech-Star supplies the ROF1375291/1 as a tested pull from decommissioned Ericsson equipment, suitable for engineers who need a working replacement processor card, a hot spare, or stock to support an ongoing maintenance contract.
