Ericsson ROJ208317-1 AXE Telecom System Card / Module

The Ericsson ROJ208317-1 is documented as a Local Reference Board (LRB) within the Ericsson AXE switching platform’s timing and synchronisation subsystem. The LRB’s role is to deliver a high quality, locally generated clock signal to the exchange’s Clock Generation Boards (CGBs), working alongside the Incoming Reference Board (IRB) to give an AXE exchange a resilient, accurate timing source even where an external reference is degraded or unavailable. Stable timing is fundamental to an AXE exchange’s ability to switch calls and data correctly, so the LRB is considered a core part of the system rather than an optional extra. Because these boards are no longer manufactured, operators running legacy AXE platforms typically source replacements as tested used or refurbished stock, as offered here. This unit is supplied as genuine Ericsson hardware, tested before dispatch. Tech-Star (UK-based, shipped worldwide) stocks a broad range of legacy Ericsson AXE timing, switching and interface cards.
