GETTING STARTED
This chapter provides basic installation instructions including the list of the packaging contents and also
description of the LED patterns.
Equipment Packaging
Table 3: Equipment Packaging
Note: Check the package before installation. If you find anything missing, contact your system administrator.
Connecting DP760
To setup the DP760 DECT Repeater, please follow the steps below:
Figure 2: DP760 Back View
There are two options to connect DP760 DECT Repeater: AC power or Power over Ethernet (PoE)
Connecting via AC power
1. Connect the micro-USB connector into the related port on the repeater station and connect the
other end of the power adapter into an electrical power outlet.
2. Connect the supplied Ethernet cable between the Internet port on the DP760 DECT Repeater and
the Internet port in your network or the switch/hub device port.
DP760
1 DECT Unit.
1 Universal power supply 5V.
1 Ethernet cable.

DP760 User Manual
Connecting via PoE
To connect the DP760 DECT Repeater using PoE, you need to connect the Ethernet cable provided (or
3rd party network cable) between the Network Socket on the repeater station to Ethernet port of your PoE
switch/hub.
DP760 Implementation Architecture
The DP750 Base Station can support up to 5 DP760 DECT Repeater stations to extend the coverage area
of the base in all directions, including through floors and ceilings using star or daisy chain configuration as
displayed on the following diagrams. The repeater determines automatically if is better to utilize star or
daisy chain configuration depending on its deployment location.
When a repeater powers on, it searches for signals from the base and any other repeaters registered to the
same base. The repeater will automatically connect to the strongest available signal.
The base can hand-off calls to the repeaters as the user moves from one coverage area to another. When
connected to the repeater, the DP720 handsets operate as it’s connected to the base, and the hand-off
from the base to the repeater can be completely invisible to the end user, even during an active call.
Note: DP760 can relay up to 2 concurrent calls in star configuration and 1 concurrent call in daisy chain
configuration.

In star mode configuration, the coverage area of the repeaters should overlap the coverage area of the
base station.

CONFIGURATION GUIDE
The DP760 can be configured via the Web GUI embedded using PC's web browser. By default, DP760 is
configured to obtain IP address from DHCP server where the unit is located and can be also discovered
using UPnP feature (by default enabled).
Configuration via Web Browser
The DP760 embedded Web server responds to HTTP/HTTPS GET/POST requests. Embedded HTML
pages allow a user to configure the DP760 through a Web browser such as Google Chrome, Mozilla Firefox
and Microsoft’s IE.
Note: If DP760’s IP is known; users can access to its web interface by entering the IP address in their web
browser from a computer connected to same network.
