Adding M5 repeaters in a multicell environment
Introduction
Step-by-Step Guide
Reset procedure
Introduction
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 halves the maximum number of bases with each repeater per base. If you still
decide to add one or more repeaters, please be sure to read the following tips and tricks to ensure proper operation.
Step-by-Step Guide
Make sure your installation complies with the limits.
In a multicell, you can have:
50 base stations with 3 repeater per base station
or base station with maximum 127 1 repeater per base station
or base stations and254 no repeater
After deciding which of these options to use, please configure this in the web interface under Multicell:
Use on the bases and on the repeater - look for latest version here: latest firmware version DECT M-Series Firmware
Automatic vs manual mode: when using repeaters in a multicell we recommend to use registration, because automatic registration manual
means that you cannot control to which base the repeater is registered to, so you might have unexpected connections. You can also try
automatic, but if that fails please switch to manual.
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 ( ). For example in the below image, the RPN for IP address 10.110.30 112 is RPN08:not the "DECT sync source" column
The Snom Repeater can be used to extend the DECT coverage area between one base and handsets. M5 A repeater cannot extend the
coverage area between one base and another base.

You only have the choice between , which thus determine the maximum number of bases as well as repeaters three switching states
per base. It does not matter whether you equip only one base with one repeater ( ) or 2-3 repeaters ( ) according to your 127/1 50/3
choice or all bases equally.
Note: No matter which setting you have chosen, you can install a in a multi-cell with M700 or M900 maximum of 100 M5 repeaters

Introduction to M5 Repeaters

Step-by-Step Guide for M5 Repeaters

Complying with Installation Limits

Ensure installation adheres to limits, choosing between 50/3, 127/1, or 254/0 base/repeater combinations.

Using Latest Firmware

Utilize the latest firmware versions for both bases and repeaters for optimal performance and compatibility.

Registration Modes: Manual vs. Automatic

Recommend manual registration for control, as automatic mode may lead to unexpected repeater connections.

Manual Registration RPN Entry

For manual registration, enter the RPN of the base the repeater should connect to, found in the base station table.

Reset Procedure for M5 Repeaters

Performing the Reset Sequence

Follow specific plug-out and plug-in sequences within defined timeframes to reset the repeater.

Access Code for Registration

The access code must be 0000 for a repeater to connect successfully to the base station.

One-by-One Repeater Registration

Overview

The Snom M5 Repeater is a device designed to extend the DECT (Digital Enhanced Cordless Telecommunications) coverage area within a multi-cell environment, specifically for use with Snom M700 or M900 base stations. Its primary function is to enhance signal reception for handsets in areas that might otherwise experience weak or no DECT coverage, particularly at the end of a DECT chain. While it can significantly improve coverage, it's important to note that a repeater cannot extend the coverage between two different base stations; its role is to expand the reach of a single base station.

Function Description:

The M5 Repeater acts as an intermediary, receiving signals from a base station and retransmitting them to extend the range for DECT handsets. This is particularly useful in larger buildings or complex layouts where a single base station's signal might not reach all desired areas. When integrated into a multi-cell system, the repeater helps to create a more robust and seamless communication network. However, its use in a multi-cell installation is generally recommended only under specific circumstances, as adding repeaters can impact the overall system capacity by halving the maximum number of bases supported per repeater. The system offers flexibility in configuration, allowing users to choose between different combinations of base stations and repeaters per base station, such as 50 base stations with 3 repeaters per base, 127 base stations with 1 repeater per base, or 254 base stations with no repeaters. Regardless of the chosen configuration, a multi-cell system can support a maximum of 100 M5 repeaters.

Usage Features:

To ensure optimal performance and avoid unexpected connections, manual registration of the M5 Repeater is recommended, especially in multi-cell setups. This allows the user to precisely control which base station each repeater connects to. During manual registration, the Repeater Number (RPN) of the target base station must be entered. The RPN can be found in the "Bases table" within the "Multicell" section of the web interface, corresponding to the IP address of the desired base.

The installation process involves several critical steps to ensure the repeater functions correctly within the DECT environment. First, the installation must comply with the system's limits regarding the number of base stations and repeaters. The system offers three distinct switching states that dictate these maximums, and the chosen state must be configured in the web interface under "Multicell > Base station settings." It's crucial to ensure that both the base stations and the repeater are running the latest firmware version to benefit from the most recent features and stability improvements.

For successful operation, all base stations in the system must utilize the same time server, and that server must be functioning correctly. Furthermore, the DECT signal level between the repeater and its connected base station should not be less than -75dBm to maintain a reliable connection. If issues arise with re-configuring a repeater or re-connecting it, a reset procedure is available.

Maintenance Features:

The M5 Repeater includes a straightforward reset procedure for troubleshooting or re-configuration. This involves a specific sequence of plugging the device in and out:

  1. Unplug the repeater.
  2. Plug it in for 1 to 5 seconds, then unplug it.
  3. Plug it in for 25 to 35 seconds, then unplug it. This reset can help resolve connectivity problems or prepare the repeater for a new configuration.

When adding a repeater to the system, an access code of "0000" is required for it to connect. It is also advised to register repeaters one by one to simplify the process and identify any potential issues more easily. Regular firmware updates for both base stations and repeaters are a key maintenance practice, ensuring the system benefits from bug fixes, performance enhancements, and new functionalities. The availability of the latest firmware can be checked through the provided resources. Adhering to best practices, such as maintaining appropriate signal levels and using manual registration in multi-cell environments, contributes significantly to the long-term stability and performance of the DECT system.
