Cisco IP Phone 8851/61 Key Expansion Module

Product overview

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.

Features and benefits

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.
