A50030651002 NEC NEC SL1000 Phone Accessory

The NEC A50030651002 is a DESI (Direct Extension Station Identification) label strip designed for 24-button digital telephones in the NEC SL1000 business communications system. This accessory provides a printed or writeable overlay that sits beneath the transparent button caps, allowing users to label programmable function keys with extension names, features, or speed dial numbers.

DESI strips are essential accessories for NEC SL1000 digital handsets, enabling clear identification of programmed buttons in reception, attendant, and high-call-volume positions. The 24-button format corresponds to NEC’s larger digital telephone models within the SL1000 range, typically used by operators or users requiring extensive one-touch access to extensions and features.

The NEC SL1000 is a small-to-medium business PBX platform that remains in service across many UK installations. While this system is considered a legacy product, replacement DESI strips remain in demand for organisations maintaining existing SL1000 deployments.
