The large LCD displays of the Cisco IP Phone 8851/61 Key Expansion Module allows for quick and easy identification of associated buttons. Using the settings menu of the IP Phone 8851, 8851NR, and 8861 models, you can adjust the brightness of the individual KEM LCD according to your preference.

The primary function of the 8851/61 Key Expansion Module is to provide additional keys for directory numbers, speed dial, or programmable feature keys to the IP Phone 8851, 8851NR, and 8861 models. These keys are illuminated, and when configured as directory numbers or shared-line keys they allow for easy identification of line status. The 8851/61 Key Expansion Module is an ideal call-coverage tool. It provides features that are similar, but not intended to be directly comparable to those of traditional Direct Station Selection/Busy Lamp Field (DSS/BLF) modules; therefore, it is neither an operator nor an attendant console.

The two illuminated page buttons below the Cisco IP Phone 8851/61 Key Expansion Module display allow you to shift between the first and second page of 14 buttons, providing access to all 28 keys.
