Summary

This article describes how to expand the radio coverage of an IP 600 Dect Systems by using repeaters and what scenarios are possible. Furthermore the configuration of repeaters in the different scenarios is described, as well as how to measure the radio coverage.


Information

First of all a small notice: As per all DECT systems also with the IP 600 are some things to bear in mind. You should have look at the conditions on site. Walls and doors made of concrete or ferroconcrete can of course reduce the transmitter/receiver power. For this reason you should test if you if you receive Dect signals on any location you need them, before you finally install the repeaters.

Installation:
Altogether you can connect up to 6 repeaters to one IP 600 base station. At the same time the maximal allowance of repeaters to connect in series is three. So the following scenarios can be realized.

Note: Please keep in mind that only two concurrent calls are allowed in a repeater zone.

Measuring of the radio coverage:
As you can see in the diagram above, you will have optimal radio coverage, if the respective zones overlap each other at round about 50%. This requires of course a measurement. A simple measurement can be done directly with a handsets of the IP 600. Of course this measurement is not as exact as a professional measurement by an expert, but results in good approximate values. To start the measurement, please type in the following characters on the handset: *99989*. Then press the "Mute" button.
Afterwards you will see the following on the display:

RPN:
RSS:
01 64 94 360

The lines "RPN:" and "RSS:" can be ignored in the context of measurement. Important are the values in the last line.
The first value (here "01") shows the device (base station or repeater) the handset is connected to. More information concerning this numbers, you will find below in the chapter that deals with the configuration of repeaters.
The second value (here "64") is the so called "Q-Value". The Q-Value represents the bit failure rate in the communication between the base station and the handset. If these value falls down to "52" or lower, the handset will try to connect to another device. That means that the limit of the radio coverage is reached.
The third value (here "94") is the so called "RSSI-Value" and shows the actual field strength. If this value falls down to "70" or lower, it is time to use a repeater.
So activate the measurement, move around and have a look on the RSSI value to identify the locations for a repeater. Please keep in mind that the human body itself can have influence on the signal strength. So please try what happens, if you shield the handset, to consider Worst-Case scenarios.

After the decision where to place the repeaters, they have to be configured.

To know to what base station or other repeater the Dect signals have to be delivered, every Dect device has its own number. The IP 600 base station has always the number "1". The number of a repeater is configurable. To configure a repeater you need the IP600 Service Tool, an appropriate cable, as well as a PC with a serial interface. This cable can be purchased by Swyx dealers. A link to download the Service Tool can be found at the end of this article.

After connecting the PC with the repeater, please start the Service Tool and select the tab "Communications".

Please choose the appropriate COM Port and choose as Baudrate "PP1-PP4 + 1G8 Repeater (9600 baud)". If all settings are correct, the message "Repeater connected" should appear in the taskbar after pressing the button "Set Comport".
Then the configuration of the repeater can begin.

Please to go the tab "Repeater". You will see the following:

Before we can start the configuration, you have to select the correct repeater type. Necessary is "Residentiel Base", but as default the Service Tool is configured on "CCFP 1550". To change this, please click on the button "Residentiel base". The dialog should then present the following.

Configuration: Residentiel Base

The different fields in detail:

In the field "Octal" please enter the ARI of the IP 600 base station. This value can be found within the web interface of the base station.

In the field "Base to synchronize on" you have to enter the number of the device, the repeater shall communicate with. Different example you will find later in this article.

With "Repeater Number" you define the number of this device. This number has to be in a range from 2 to 7 and must be unique in the complete system.

If you activate the checkbox "Debug Bip", the repeater will send a short beep tone every 5 seconds to the handset within the repeater zone. This tone might be helpful to measure the radio coverage.

Clicking the button "Write to repeater" will save the configuration to the repeater.

Note: If the fields are yellow, the configuration is not saved.

Concrete examples:

1. Connecting a single Repeater to a IP 600 Dect System:
The ARI of the IP 600 is for example 000046474216.
Because the base station has always the number "1", the configuration may look like the following.

The repeater will communicate with the base station (number "1") und its own number is "2". If you want to connect other repeaters directly to the base station, you can configure the repeaters like this one. Only the own number must be different of course.

2. Connection multiple repeaters in series

The first repeater will be configured as described above, because it is connected directly to the base station.
The second repeater shall communicate with this first repeater. For this reason, the value "Base to synchronize on" must be set to the number of the first repeater, in this example "2". The ARI will not change. The own repeater number can be set to "3", as you can see in the following screenshot.

With "Write to repeater" the configuration will be saved.
In the same manner you can configure a third (and last) repeater.
* Identical ARI
* "Base to synchronize on" will be set to "3"
* "Repeater number" can have the value "4" for example.

Altogether the following scenario can be configured.

After saving the configuration, you can install the repeaters at the defined location and connect it to the power supply system.
