First to provide unconstrained bandwidth to desktop applications, the Cisco Unified IP Phone 7971G-GE delivers the latest technology and advancements in Gigabit Ethernet VoIP telephony. It not only addresses the needs of an executive or major decision maker but also brings network data and applications to users quickly with its Gigabit Ethernet port for integration to a PC or desktop server. This state-of-the-art Gigabit Ethernet IP phone is “feature identical” to the Cisco Unified IP Phone 7970G. It also includes a backlit, high-resolution color touch-screen display (320 x 234, 12-bit display with 4096 colors) for easy access to communication information, timesaving applications, and features. It also helps customers and developers deliver more innovative and productivity-enhancing Extensible Markup Language (XML) applications to the display. Offering access to eight telephone lines (or a combination of lines and direct access to telephony features), a high-quality, hands-free speakerphone, and a built-in headset connection, the phone can be powered through IEEE 802.3af power over Ethernet (PoE) or a local power supply (part number CP-PWR-CUBE-3=). The Cisco Unified IP Phone 7971G-GE does not support Cisco Prestandard PoE. Sold without power supply (CP-PWR-CUBE). It is used to provide power to Cisco IP phones when in-line power over Ethernet is not available.
