Cisco ICS 7750 System Description

Line buttons that are assigned with directory numbers can be illuminated to show
the line status information identified in Table 6-4.
Each button that is not used as a directory number or line key can be programmed
as a speed-dial key by using the Cisco IP Phone User Options web page.
To attach the expansion module to a Cisco IP Phone 7960, use the single footstand
for one module. Use a double footstand to attach two modules.
When the Cisco 7960 uses a local power cube, a single expansion module can
receive power from the cube attached to the Cisco 7960. If the Cisco IP
Phone 7960 receives in-line power, the single expansion module requires a power
cube.
For two expansion modules attached to the Cisco 7960, a separate power cube is
required for the expansion modules.
