IP add-on modules

CP-CKEM-W=,Unified IP Color Key Expansion Module Product Overview
Call coverage is a critical capability for administrative assistants and others who must monitor, manage, and cover the status of calls. This capability requires the ability to instantly determine the status of numerous lines beyond those of the Cisco® Unified IP Phone 9971, 9951, and 8961 models.
The Cisco Unified IP Color Key Expansion Module extends the capabilities of the Cisco Unified IP Phone 9971, 9951, and 8961 models with additional buttons and a color LCD display. This key expansion module adds 18 physical keys with access to 18 additional keys through the page keys for a total of 36 additional keys. You can connect up to three Cisco Unified IP Color Key Expansion Modules to the Cisco Unified IP Phone 9971, up to two key expansion modules to the Cisco Unified IP Phone 9951, and one key expansion module to the Cisco Unified IP Phone 8961.
You can connect the Cisco Unified IP Color Key Expansion Module to the Cisco Unified IP Phone 9971, 9951, and 8961 models directly in the traditional side-by-side fashion or indirectly in a tethered fashion with an optional tethered cord.
The Cisco Unified IP Color Key Expansion Module comes with a foot stand and all necessary hardware to connect it directly to the base device. Tethered configuration requires the purchase of the tethered cord.
The key expansion module also articulates in the same manner as that of the Cisco Unified IP Phones it connects to, allowing you to match the same articulation angle.

Features and Benefits
The large LCD display of the Cisco Unified IP Color Key Expansion Module allows for quick and easy identification of associated buttons. Using the Preferences menu of the Cisco Unified IP Phone 9971, 9951, and 8961 models, you can adjust the brightness of the individual key-expansion-module LCDs according to preference.
You can program feature key buttons on the Cisco Unified IP Color Key Expansion Module as a directory number, line key, or speed-dial key. The buttons are illuminated, and when configured as a directory number or shared-line keys they allow for easy identification of call state. This capability provides features that are similar to those of typical direct station selection/busy lamp field (DSS/BLF) modules but are not intended to be directly comparable to those of traditional DSS/BLF modules. The Cisco Unified IP Color Key Expansion Module is neither an operator nor an attendant console. Its primary function is to provide the Cisco Unified IP Phone 9971, 9951, and 8961 models with additional keys for features such as speed dial or directory numbers. The illuminated buttons make it easy to determine line status, making the Cisco Unified IP Color Key Expansion Module an ideal call-coverage tool.
The two illuminated page buttons beneath the display of the Cisco Unified IP Color Key Expansion Module allow you to shift between the first and second pages of 18 buttons, providing access to all 36 keys, 18 at a time.
