Overview (CP-8851-W-K9)

Speakerphone ● A full-duplex speakerphone gives you flexibility in placing and receiving calls with hands free. For added
security, the audible dual tone multifrequency (DTMF) tones are masked when the speakerphone mode is
used.
Headset Port ●  The handset is a standard wideband-capable audio handset (connects through an RJ-9 port)
●  The standard coiled cord has a custom end for concealed cable routing beneath the phone (cord length is approximately 21 in. [55 cm] coiled and up to 72 in. (183 cm) extended)
●  The handset is hearing aid-compatible (HAC) and meets Federal Communications Commission (FCC) loudness requirements for the Americans with Disabilities Act (ADA). You can achieve Section 508 loudness requirements by using industry-standard inline handset amplifiers such as Walker Equipment W-10 or CE-100 amplifiers. The dial pad is also ADA-compliant
USB ● A side USB port enhances the usability of call handling by enabling wired or wireless headsets, as well as
provides up to 500-mA power output at 5V or 2.5W for smartphone charging.
Ethernet switch ● An internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000BASE-T Ethernet
network (IEEE 802.3i/802.3u/802.3ab) through a RJ-45 interface with single LAN connectivity for both the
phone and a co-located PC.
● The system administrator can designate separate VLANs (IEEE 802.1Q) for the PC and phone, providing
improved security and reliability of voice and data traffic.
