Nortel NT2K22XH35 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NT2K22XH35 is a Key Expansion Module (Keylamp Module) in beige, a 22-button add-on unit for compatible Nortel Meridian digital deskphones such as the M2616, adding extra programmable line and feature keys beyond those built into the base handset. It attaches to the side of the phone and requires a matching footstand (single or dual) to support the combined phone-and-module assembly on the desk. Key expansion modules of this type are used where a user’s call volume or number of monitored lines exceeds the base phone’s own key capacity, common on reception or attendant positions. Genuine Meridian key expansion modules of this generation remain in active use, and spares like this one are a routine requirement for expanding or replacing a faulty module. Confirm the exact host phone model and footstand compatibility against your installation before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel Meridian accessories to support ongoing network maintenance projects.
