Applications
The Merlin LEGEND and Merlin Magix were AT&T/Lucent's primary small-to-midsize business phone systems of the 1990s and early 2000s, used widely in offices requiring a fully featured key system or hybrid PBX. The DS1 trunk module provides the critical T1 interface that allows these systems to connect to a T1 line from the carrier, supporting 24 voice channels over a single DS1 circuit — a far more cost-effective arrangement than individual analog lines for businesses with higher call volumes. Systems needing to add or replace a T1 trunk capability rely on modules exactly like this 517E15. Rebranding over the years moved these systems from AT&T to Lucent Technologies to Avaya, but the hardware remains the same, and the installed base is still maintained by telecom technicians and businesses running legacy Merlin systems today.
This Lucent Merlin 517E15 100D 1 DS1 Trunk Module was pulled from a working phone system. It has not been powered up or tested at our facility, but it was removed from an operational Merlin PBX environment where it was previously in use. The housing shows general yellowing and surface discoloration typical of older telecom equipment of this era, but no cracks, broken tabs, or connector damage are visible. The backplane card-edge connector and front RJ48 port appear intact. Please view our photo set and contact us if you have any questions.
