Adding an M5 or M6 repeater in a multicell environment

Introduction

The Snom M5 or M6 repeater can be used to extend the DECT coverage area between one base and handsets: a repeater cannot extend the coverage area between one base and another base

Here can you find a step by step guide, How to register an M5 or M6 repeater to a base station

Adding a repeater to an M700/M900 multi-cell installation is only recommended in certain circumstances (e.g. to improve reception at the end of a DECT chain) and should otherwise be avoided as the use of repeaters reduces the maximum number of bases

Step-by-Step Guide

Make sure your installation complies with the limits.
You only have the choice between three switching states, which thus determine the maximum number of bases as well as repeaters per base
It does not matter whether you equip only one base with one repeater (127/1) or 2-3 repeaters (50/3), all bases will follow the same choice
Note: No matter which setting you have chosen, you can install a maximum of 100 repeaters in a multi-cell with M700 or M900 bases

In a multicell, you can have:
1. 50 base stations with 3 repeater per base station
2. 127 base station with maximum 1 repeater per base station
3. 254 base stations and no repeater
  
  After deciding which of these options to use, please configure this in the web interface under Multicell:
Use latest firmware version on the bases and on the repeater - look for latest version here: DECT M-Series Firmware
Automatic vs manual mode: when using repeaters in a multicell we recommend to use manual registration, because automatic registration means that you cannot control to which base the repeater is registered to, so you might have unexpected connections
When using manual registration, you must enter the RPN of the base to which the repeater should connect to
To find out the RPN of a base, you can look in the bases table in the Multicell section, find the IP address of your base and for that row of the table get the value under the RPN column (not the "DECT sync source" column)
For example in the below image, the RPN for IP address 10.110.30 112 is RPN08
Make sure that all bases use the same time server and that the time server works correctly
It is also important that the DECT-dBm level between repeater and base is not lower than -75dBm
Whenever you need to re-configure a repeater or having problems re-connecting, you should reset it and try again
