The primary function of the Cisco IP Phone 8800 Key Expansion Module is to provide additional keys for directory
numbers, speed dial, or programmable feature keys to the IP Phone 8851 and 8861. These keys are illuminated,
and when configured as directory numbers or shared-line keys they allow for easy identification of line status. The
Cisco IP Phone 8800 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 8800 Key Expansion Module display allow you to shift
between the first and second page of 18 buttons, providing access to all 36 keys.
Table 1 describes the features and benefits in more detail.
