Equipment Packaging

DP760

1 DECT Unit. 1 Universal power supply 5V. 1 Ethernet cable. 1 Quick Installation Guide. 1 GPL Statement.

Connecting DP760

To set up the DP760 DECT Repeater, please follow the steps below:

There are two options to connect DP760 DECT Repeater, either with the 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.

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 architecture as displayed on the following diagrams.

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 first 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 is 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.

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

DP760 LED Patterns

The DP760 has 5 LED lights. Please refer to following table describing the status of each LED.

LED	Status
	Indicates Power ON/OFF.
	Indicates access to the network. Solid ON: When there is access to the network. Blinking: If there is no access to the network.
	Indicates status of the association between DP760 and DP750 Blinking: When the DECT station is scanning for available RFPs. Solid ON: When the association between DECT repeater and Base station is operational.
	Indicates status of the association between DP760 and DP750 during calls. Solid ON: When there are no active calls and the association between DECT repeater and Base station is operational. Blinking: During active calls.
	Indicates status of the association link between the DP760 and DP750. Solid ON: When the association between DECT and Base station is operational, and link is excellent. Blinking: Long ON, 1x short OFF if the association link is good. Long ON, 2x short OFF if the association link is weak. Long ON, 3x short OFF if the association link is poor

CONFIGURATION GUIDE

The DP760 can be configured via the Web GUI embedded using a Web browser. By default, DP760 is configured to obtain IP address from DHCP server where the unit is located and can be 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 Internet Explorer.

Note: If DP760 has a known IP, users can access to its Web GUI by entering the IP address in their Web browser on a device connected to same network.

Accessing the Web GUI using UPnP Feature

DP760 supports UPnP feature (by default enabled) for auto discovery by computers in same network. Please refer to following steps to access DP760 Web GUI:

1. Power on DP760 and connect it to the network.

3. Access Network directory on the computer.
4. Locate DP760 – <MAC Address> device and double click on it to access Web GUI.

5. Enter admin’s username and password and press Login button to access the configuration menu. (Starting HW version 1.3A the default admin username is ‘admin’ while the admin password is the random password that can be found on the sticker at the back of the unit. For lower hardware versions; the default username and password are: admin/admin)

Accessing the Web GUI using DP750 Repeater Management Mode

The repeater management mode on the DP750 allows managing discovered / paired re­peater stations and accessing the DP760 Web GUI from DP750 Web GUI. Please refer to following steps to access DP760 Web GUI using DP750 repeater management mode:
