These capabilities provide features that are similar to typical Direct Station Selection/Busy Lamp Field (DSS/BLF)

modules but are not intended to be directly comperable to traditional DSS/BLF modules. The Cisco Unified IP Phone

Expansion Module 7915 is not an operator or attendant console. The primary function of this module is to provide the

Cisco Unified IP Phone 7962G, 7965G, and 7975G models with additional keys for features such as speed dial or

directory numbers. The illuminated buttons provide ease of line status, making the Cisco Unified IP Phone

Expansion Module 7915 an ideal call-coverage tool.

The two illuminated page buttons beneath the display of the Cisco Unified IP Phone Expansion Module 7915 allow

you to shift between the first and second pages of 12 buttons, providing access to all 24 keys, 12 at a time (Table 2).

Table 3 lists the features of the Cisco Unified IP Phone Expansion Module 7915.
