Cisco IP Key Expansion Module

The Cisco IP Phone 8800 Key Expansion Module extends the capabilities of Cisco IP Phone 8851, 8861, and 8865 models with additional buttons and a color LCD display. This key expansion module adds 18 physical keys with access to 18 additional keys, using the page keys, for a total of 36 additional keys. You can connect up to three 8800 KEMs to the IP Phone 8861 and 8865, and up to two 8800 KEMs to the IP Phone 8851.

The Cisco IP Phone 8851 models include the standard 8851 model and the 8851NR model, which is the nonradio 8851 model designed for military and other customers who need a key expansion module (KEM) but cannot place phones with Bluetooth or other radios on their premises. All attributes of the 8851 and 8851NR are identical except that the 8851 has no Bluetooth radio on its board.
