A
Digital
Cordless Handset base phone requires only a line cord to the phone system; AC power
isn’t
needed because the base phone receives power from the phone system via the line cord.
An
IP
Cordless Handset base phone receives PoE. If
PoE isn’t already being supplied, you’ll need to install
the separately purchased
PoE adapter
(sold in five-
packs as ESI part # 5000-0437). The diagram at right
shows the necessary connections.
Note:
If the PoE equipment plugs into AC outlets and a
power failure occurs, all IP Cordless Handsets on
the system will be unable to originate or receive
phone calls. Therefore,
either
:
(a.)
use an
appropriately sized uninterruptible power supply
(UPS) to power
all
the IP equipment (base
phone, PoE adapter, router,
etc.
) involved in
making phone calls
or (b.)
have a traditional
POTS (“plain old telephone service”) phone
available for making and receiving CO calls.
Once the base phones are installed and the Cordless Handsets charged, the Cordless Handset will auto-seek
an available channel:
Note:
Feedback may result if the Cordless Handset is within three inches of an ESI desktop phone.
ESI Cordless Handset II Repeater
The optional
ESI Cordless Handset II Repeater
extends the coverage area of the ESI Cordless Handset II in
all directions, including up and down.
If Repeaters are installed so their coverage area overlaps that of the base phone, the base phone can hand
off calls to the Repeaters as the user moves from one coverage area to another. When it’s connected to a
Repeater, the ESI Cordless Handset II operates exactly as it does when connected to its base phone, and the
handoff from the base phone to the Repeater occurs seamlessly without disturbing the end user, even during
an active call.
Each ESI Cordless Handset II base phone supports up to
six
repeaters, regardless of configuration.
•
Each Repeater supports up to two direct connections to other Repeaters.
•
No Repeater can be more than three connections — or
hops
— from the base phone.
All Repeaters, regardless of configuration, must be registered to the base phone.
All Repeaters must be registered directly to the base and then installed in their final locations; each Repeater
will determine the best signal path back to the base station.
For detailed information on installing Repeaters, refer to the ESI Cordless Handset II Repeater Installation
Manual
(ESI # 0450-1248).
