	ringer sounds through the User Preference menu. Network Configuration preferences also
	can be set up (usually by the system administrator). Configuration can be set up either
	automatically or manually for Dynamic Host Control Protocol (DHCP), Trivial File Transfer
	Protocol (TFTP), Cisco Unified Communications Manager, and backup Cisco Unified
	Communications Manager instances. Other available Settings submenus include Device
	Configuration, Security Configuration, and Model Information.

	used to awaken the display. Inactivity period is configured by the system administrator.
Ethernet Switch	Internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000 BASE-
	T Ethernet network through an RJ-45 interface with single LAN connectivity for both the
	phone and a colocated PC. System administrator can designate separate VLANs (802.1Q)
	for the PC and phone, providing improved security and reliability of voice and data traffic.
Headset Port	Dedicated headset port eliminates the need for a separate headset amplifier and allows the
	handset to remain in its cradle, making headset use simpler. Both wideband (G.722) and
	narrowband headsets are supported.
Volume Control	Provides easy decibel-level adjustments for the speakerphone, handset, headset, and
	ringer. The handset is hearing aid-compatible. Additional volume control gain can be
	achieved using an inline handset amplifier.
Adjustable Foot-Stand	Stand is adjustable from flat to 60 degrees to provide optimum display viewing and
	comfortable use of all buttons and keys. The foot-stand is keyed to match standard wall-jack
	configurations for wall mounting. Optional wall-mount brackets are also offered.

	14 additional buttons for programming directory numbers or speed dials. Up to two
