Applications
The Avaya 008 MLX module was designed for use in the AT&T / Lucent / Avaya Merlin Legend business telephone system, a widely deployed PBX platform throughout the 1990s and into the 2000s. The Merlin Legend used a modular card-cage architecture: station modules like the 008 MLX were installed into the control unit to define the number and type of telephone sets supported. The 008 MLX specifically provides eight ports for MLX-series digital handsets, which used a proprietary digital protocol over standard twisted-pair wiring. These modules are still sought after by businesses and support organizations maintaining Merlin Legend systems, as replacement and expansion cards are no longer manufactured and must be sourced from the used market. Compatible MLX telephone sets include the MLX-5, MLX-10, MLX-16, MLX-20L, and related models.
This Avaya 008 MLX 8-Port Digital Telephone Module has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in use. The module shows light wear typical of a used PBX card — the housing is intact and the port connectors appear clean. Please view our photo set and contact us if you have any questions.
