NEC Display Solutions SL1100 12-Button Full-Duplex Telephone (Black)

NEC SL1100 12-Button Office Telephone

The NEC SL1100 is a full-duplex desktop telephone with twelve programmable buttons and a backlit alphanumeric display. It is designed for businesses using the SL1100 communication system that need direct access to lines, speed-dial entries and system features from a single handset. The handset supports hands-free conversation and provides visual feedback for call status, caller ID and system alarms. It suits office staff who handle moderate call volumes and rely on feature keys rather than a touchscreen.

Check SL1100 system compatibility

Before ordering, confirm that your SL1100 main unit has a free digital station port and sufficient power budget for an additional endpoint. The telephone draws power from the system, so no local mains adapter is required, but the cabinet must support the extra load. Verify that the site cabling uses the pin-out expected by the SL1100 digital interface; mismatched wiring will prevent the handset from registering. Ensure the system firmware revision supports the feature set listed for this model.

Bundled handset cord and line cord only

The package includes the handset, a coiled handset cord and a straight line cord for connection to the wall jack or patch panel. No separate power supply, wall-mount bracket or configuration software is supplied. Programming of speed-dial numbers, account codes and feature keys is performed through the SL1100 system administration interface, not via a PC application shipped with the phone. The backlit display and full-duplex speakerphone operate immediately once the endpoint is registered.
