The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco IP Phone 8851/61 Key Expansion Module
Call coverage is critical for administrative assistants and others who must monitor and manage the status of calls. It requires the ability to instantly determine the status of numerous lines beyond those of the Cisco IP Phone 8851, 8851NR, and 8861 models.
Note: The Cisco IP Phone 8851 and 8861 models includes the standard 8851 model and the 8851NR model, which is the nonradio 8851 and 8865 models. The NR models are 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 8851NR has no Bluetooth radio on its boards.
The Cisco IP Phone 8851/61 Key Expansion Module extends the capabilities of Cisco IP Phone 8851, 8851NR, and 8861 models with additional buttons and a color LCD display. This key expansion module adds 14 physical keys with access to 14 additional keys, using the page keys, for a total of 28 additional keys. You can connect up to three 8851/61 Key Expansion Modules to the IP Phone 8861 and up to two 8851/61 KEMs to the IP Phone 8851 and 8851NR.
The 8851/61 Key Expansion Module comes with a foot stand and all necessary hardware to connect it directly to the base device in the traditional side-by-side fashion.
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.

Hardware and Power-Saving Features |
|
Graphical display |
The 3.5-inch graphical (TFT) color displays provides 16-bit color depth and 320 x 480 effective pixel resolution, with backlight. The display also supports localization requiring double-byte Unicode encoding for fonts. |
Articulation |
You can articulate the display to match the same angle as the Cisco IP Phone 8851, 8851NR, and 8861 that it is connected to. |
Directory-number and feature buttons |
The module has 14 physical buttons (28 using page keys). |
Page buttons |
Use the two page buttons to access each page of 14 buttons and provide phone status. |
Sleep or inactivity mode |
When Cisco IP Phone 8851, 8851NR, and 8861 models are in power-saving sleep or inactivity mode, the Cisco IP Phone 8800 KEM is also in sleep or inactivity mode. Pressing any button on the key expansion module causes the display to awaken. The system administrator configures the inactivity period. |
