Applications

The Merlin Legend and Merlin Magix are Lucent/Avaya key/hybrid PBX platforms widely deployed in small-to-medium business telephone systems from the mid-1990s through the 2000s. The 408 GS/LS-ID-MLX card slots into the system cabinet and expands capacity by adding both outside CO line appearances and MLX digital station appearances simultaneously. GS/LS-ID signaling supports caller ID pass-through from the central office, and MLX ports connect Avaya's proprietary MLX-series digital desk phones. These cards remain in demand for legacy Merlin system maintenance, adds/moves/changes, and spare-parts inventory at organizations still running Merlin Magix or Merlin Legend infrastructure.
