Ericsson 1/TSR9011219/15000 MD110 Telecom System Card / Module

The Ericsson 1/TSR9011219/15000 is a 15 metre DECT synchronisation cable for the ELU31/1 board used in the Ericsson MD110 and BusinessPhone PBX. The ELU31/1 is the DECT interface card that connects cordless DECT base stations to the exchange, and this cable carries the synchronisation signal that keeps those base stations time-aligned so calls hand over cleanly as users move between radio cells. The longer 15 metre length suits installations where the DECT base stations or synchronising equipment sit some distance from the ELU31/1 card, for example across separate cabinets or floors. Correct synchronisation is essential for stable DECT coverage and consistent voice quality across a multi-cell site. This is a legacy Ericsson part that remains in demand for maintaining MD110 and BusinessPhone systems still in active service. A shorter 3 metre variant (1/TSR9011219/3000) is also available.
