Ericsson ROF1375314/1 AXE-10 / MD110 Telecom System Card / Module

The Ericsson ROF1375314/1 is a TSU (Time Slot Unit) circuit board used within Ericsson’s ROJ/ROF-series digital telephone exchange hardware, including the AXE-10 and related MD110 platforms. Time slot unit boards manage the allocation and switching of individual time slots on the exchange’s PCM highways, a core function of any time-division digital switch, ensuring that voice and signalling channels are correctly routed between line/trunk interfaces and the switching network. This exact board family is documented in reseller stock as an Ericsson TSU card (the /2 hardware revision, ROF1375314/2, is listed by telecom parts suppliers), and this /1 revision is the equivalent earlier hardware issue of the same functional board. It is offered here as a tested, refurbished spare suitable for maintaining existing installations. Boards should be matched to the specific exchange generation and software release in use. Tech-Star (UK-based, shipped worldwide) stocks a wide range of legacy Ericsson telecom hardware; enquire with your system configuration to confirm compatibility before ordering.
