The internal Cisco 2-port Ethernet switch allows
for direct connections to a 10/100BASE-T Ethernet network via an RJ-45
interface with single LAN connectivity for both the phone and a colocated PC.
The system administrator can designate separate VLANs (802.1Q) for the PC and
Cisco IP phones, providing improved information security and voice and data
reliability.
A dedicated headset port eliminates the need for a
separate amplifier when using a headset. This allows the handset to remain in
its cradle, simplifying headset use.
The handset is hearing aid compatible (HAC) and
meets Federal Communications Commission (FCC) loudness requirements for the
Americans with Disabilities Act (ADA). Section 508 loudness requirements can
be achieved using industry-standard in-line handset amplifiers such as Walker
Equipment W-10 or CE-100 amplifiers.
The dial pad is also ADA-compliant.
The foot-stand of the Cisco IP Phone 7970G 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. Two optional wall-mount
brackets are also offered.
For the Cisco IP Phone 7970G to have full display
brightness, the external power adapter is an ordering requirement. The Cisco
IP Phone 7970G can receive power down the LAN from any of the Cisco in-line
power-capable blades and boxes; however, the display screen is "half
bright" and therefore is not the recommended mode of operation.
In addition, the Cisco IP Phone 7970G supports both
the Cisco pre-standard Power over Ethernet (PoE) and IEEE 802.3af PoE.
For added information security, the audible dual
tone multi-frequency (DTMF) tones are masked when the speakerphone mode is
used.
Other Cisco IP Phone 7970G features include:
•
24+user-adjustable ring tones
•
G.711 and G.729a audio compression
•
An IP address assignment-DHCP client or statically configured
•
Comfort noise generation and voice activity detection (VAD) programming on a
system basis
