B.3
• Complies with IEEE 802.1q and 802.1p (VLAN) Layer 2 switching and prioritization.
• Complies with differentiated services (DiffServ; RFC 2475) Layer 3 Quality of Service (QoS)
implementations.
Notes: If connecting an ESI desktop IP phone to a Power over Ethernet source, the PoE cable must be connected
to the jack labeled NETWORK on the base of the phone. The jack labeled PC does NOT support or provide
Power over Ethernet.
ESI has tested each ESI desktop IP phone with several Power over Ethernet sources. For a current list of
tested devices, see www.esi-estech.com/Resellers/PoE.
Important: None of the IP phones listed in this section will work with ESI’s legacy IP E-Class or IVX
®
systems. Similarly,
previous IP Feature Phone models (including the Remote IP Feature Phone) don’t work with ESI
Communications Servers but, instead, are intended for use with only IP E-Class and appropriate, IP-enabled
IVX systems.
ESI Cordless Handsets
ESI Communications Servers also support ESI’s digital, Local IP, and Remote IP Cordless Handsets — both
the Cordless Handset II and the original ESI Cordless Handset models.
Cordless Handset II
The ESI Cordless Handset II includes seven familiar fixed feature keys, eight programmable feature keys, a
speakerphone, and a headset jack. The Base Station for the ESI Digital Cordless Handset II uses a standard
line cord and is line-powered; and the Base Station for each ESI IP Cordless Handset II (Local IP or Remote
IP) uses Ethernet cabling, and receives (and requires) Power over Ethernet (PoE). The ESI Remote IP
Cordless Handset II base station also includes a jack into which the user can plug an analog CO line. This
gives the home-based teleworker the convenience of using both home and business lines with the ESI
Remote IP Cordless Handset II. Each ESI Cordless Handset II model employs advanced DECT 6.0
technology which, as compared to the original ESI Cordless Handsets, allows more secure communications
and — through the use of one or more optional ESI Cordless Handset II Repeaters — greater range.
Original Cordless Handsets
The original ESI Cordless Handsets come in two sizes — small and large — and each includes four familiar
fixed feature keys, four programmable feature keys, and a headset jack. The Base Station for each ESI digital
Cordless Handset uses a standard line cord and is line-powered; and the Base Station for each ESI IP
Cordless Handset uses Ethernet cabling and receives (and requires) Power over Ethernet (PoE). The ESI
Remote IP Cordless Handset base station also includes a jack into which the user can plug an analog CO
line. This gives the home-based teleworker the convenience of using both home and business lines with the
ESI Remote IP Cordless Handset.
Important: Each ESI IP phone draws up to 7.25 watts
1
at 48 volts DC; therefore, each advertises itself to a Power over
Ethernet switch as a Class 3 device per the 802.3af standard. Most PoE switches adhering to this standard will
provide up to 12.5 watts for each Class 3 device.

An ESI desktop IP phone’s power consumption takes into account an optional 60-Key Expansion Console.
