IP-телефон Cisco CP-8851-W-K9= (White)

Hardware Features

Ergonomic design

The phone offers an easy-to-use interface and provides a traditional telephony-like user experience.

Graphical display

The 800 × 480, 24-bit color, 5-in. WVGA display provides scrollable access to calling features and text-based XML applications.

Handset

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.

Speaker phone

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.

Analog headset

The analog headset jack is a standard wideband-capable RJ-9 audio port.

AUX port

You can use an auxiliary port to support electronic hookswitch control with a third-party headset connected to it.

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.

Bluetooth

Bluetooth 3.0 Enhanced Data Rate (EDR) Class 1 technology (up to 66-ft [20m] range) is supported.

Hands-Free Profile (HFP) is supported for untethered headset connections and voice communications.

Phone Book Access Profile (PBAP) is supported for phone book object exchange between devices.

◦      Line keys

◦      Soft keys

◦      Back and release keys

◦      Four-way navigation and select keys

◦      Hold/Resume, Transfer, and Conference keys

Backlit indicator

The phone supports backlit indicators for the audio path keys (handset, headset, and speakerphone), select key, line keys, and message waiting.

Replaceable bezel

The phone includes a black bezel; an optional silver bezel is also orderable separately.

Dual-position foot stand

The display is easy-to-view and the buttons and keys are easy-to-use. The two-position foot stand supports viewing angles of 35 and 50 degrees; you can remove the foot stand for wall mounting, with mounting holes located on the base of the phone.

Wall-mountable

You can install the phone on a wall using an optional wall-mount kit.

Key expansion module (KEM)

The phone supports up to two KEMs to expand from 5 or 10 line buttons to 61 or 66 line buttons. You have the convenience of many speed dials or programmable features, or the necessity of following the activity of many lines.

Physical security

The phone is compatible with the Kensington Security Slot (K-Slot) antitheft system.

Power Features

IEEE Power over Ethernet (PoE)

IEEE Power over Ethernet class 3 for hardware version prior to V08, class 4 for hardware version V08 and above. In PoE class 3 case, one KEM can be attached and powered up through PoE together with the host 8851 phone, in PoE class 4 case, two KEMs can be attached and powered up through PoE together with the host 8851 phone.

The phone is compatible with both IEEE 802.3af and 802.3at switch blades and supports both Cisco Discovery Protocol and Link Layer Discovery Protocol - Power over Ethernet
(LLDP-PoE).

Cisco IP Phone Power Cube 4

This optional power cube is used as an AC-to-DC (48V) power supply for non-PoE deployments. Use of the power cube 4 also requires the use of one of the corresponding AC country cords.
