Digital phone models
The ESI-50L supports several different models of
ESI digital phones
, each of which connects to the cabinet via
standard two-wire twisted pair:
•
48-Key Digital Feature Phone
— Three-line, 56-character
1
display (backlit display available);
speakerphone; headset jack
2
; 30 programmable feature keys; the only one of the three Digital Feature
Phones that supports
VIP
or the 60-Key Expansion Consoles.
Note:
Not all modular headsets will work on the 48-Key Feature Phone’s headset jack. ESI has tested and can
recommend the following headset models:
Manufacturer:
Plantronics
— P51-U10P sound tube microphone
— P51N-U10P noise-cancelling microphone
— P251-U10P sound tube microphone
— P251N-U10P noise-cancelling microphone
Manufacturer:
GN Netcom
— GN2120 NCD 01 “over-the-head”
— GN2127 NCD 01 “on-the-ear”
Note that GN Netcom models also are available in a “-02” configuration, which wires differently and
won’t
work with ESI phones. Therefore, when ordering GN Netcom headsets for use with ESI phones,
be sure to specify the “-01” configuration.
•
24-Key Digital Feature Phone
— Two-line, 32-character display (backlit display available); speakerphone; 12
programmable feature keys.
•
12-Key Digital Feature Phone
— One-line, 16-character display; nine programmable feature keys.
Note:
When a desktop phone is in the highest upright position, use the wall-mount hook located under the
handset to secure the handset when you’re not using the phone.
ESI Cordless Handsets
The ESI-50L also supports ESI’s digital
Cordless Handsets
. Each comes in two sizes — small and large — and
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.
Expansion Consoles
The
60-Key Expansion Console
gives a designated user 60 additional programmable feature keys. The
Expansion Console is connected to its host 48-Key Feature Phone via a special cable (provided) and
doesn’t
require a separate station port of its own. Additionally, it may be connected to a
60-Key Second Expansion
Console
via a special cable (provided with the 60-Key Second Expansion Console) so that one 48-Key Feature
Phone can have a total of 150 programmable feature keys.
A maximum of four stations with one or two Expansion Consoles (60-Key and 60-Key Second) can be installed
in a
fully configured
ESI-50L system.
