Ericsson 1/TSR9011219/3000 MD110 / BusinessPhone Telecom System Card / Module

The Ericsson 1/TSR9011219/3000 is a 3 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 links cordless DECT base stations to the exchange, and this cable carries the synchronisation signal that keeps the base stations time-aligned so calls hand over cleanly as users move between radio cells. The 3 metre length suits installations where the DECT synchronising equipment sits close to the ELU31/1 card within the same or an adjacent cabinet. Reliable synchronisation is critical for stable DECT coverage and consistent call quality across a multi-cell deployment. This is a legacy component tied to Ericsson’s traditional PBX platforms, many of which remain in active service, so replacement cables of this type are still sought for ongoing maintenance. A longer 15 metre variant (1/TSR9011219/15000) is also available.
