Ericsson ROF1314309/2 MD110 Telecom System Card / Module

The Ericsson ROF1314309/2 is a TRU3 (Tone Receiver Unit) circuit board for the Ericsson MD110 private branch exchange (PBX) platform. The MD110 is a modular, scalable business communications system widely deployed across enterprise and campus telephony installations, and it relies on dedicated tone-receiver hardware to detect DTMF and other in-band signalling tones from connected lines and trunks during call set-up. Tone receiver boards such as the TRU3 are installed within MD110 line interface modules (LIM) and are essential to correct call routing and digit collection on analogue and digital extensions. This item is offered as a tested, refurbished spare suitable for maintaining existing MD110 installations or building out spare stock for planned maintenance. Boards should be matched to the specific MD110 hardware generation and software release in use. Tech-Star (UK-based, shipped worldwide) holds a wide range of legacy Ericsson/Aastra MD110 hardware; enquire with your system configuration to confirm compatibility before ordering.
