Initial release of the FortiFone FON-D72 User Guide. 2020-11-25 Updated Estimating number of base stations based upon handsets on page Removed references to version 6.0.0. The version number is not required for this guide. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Supports up to 30 FON-D72-B bases, increasing the amount of calls, handsets and range that the FON-D72 is capable of. PoE support for the bases eliminates the need for a power adapter. FON-D72-M/B base stations FON-D71-H handset FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Green – DECT Manager and Base are active and synced. Slow flashing green – active calls on Base. Off – DECT Manager and Base are not synced or offline. 4. Device key Hold for 20 seconds to restore factory defaults. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Introduction Requirements A FON-D72 configuration requires the following: 1 x FON-D72-M 1 x FON-D72-B 1 x FON-D71-H FortiFone FON-D72 User Guide Fortinet Technologies Inc.
The base station can be wall mounted using two screws set 59 mm apart. The base station may be mounted upright (A), sideways (B) or on the ceiling (C). The recommended installation height for a base station is between 1.8 and 3 meters, depending on the room height. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
5. On the FON-D72-H handsets, press the Reg softkey. The handsets will display their name and extension number on screen. To allow the base stations to take signal measurements and determine their optimal placement, make sure to complete the registration of at least one handset. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Base station overlap for synchronization to guarantee roaming and handover. The following table shows the maximum number of connection channels and handsets that can be handled in relation to the number of FON-D72-B base stations: FON-D72-B Connection channels Active handsets FortiFone FON-D72 User Guide Fortinet Technologies Inc.
The minimum distance depends on the circumstances. If there are no obstacles between them, the required distance can be from 5 to 10 meters. If there are obstacles such as absorbent walls or absorbent furniture between them, 1 to 2 meters may be sufficient. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
If several base stations with a higher sync level have been discovered, synchronization occurs with the base station that has the strongest signal. If no base stations with a higher sync level are detected, synchronization cannot occur. FortiFone FON-D72 User Guide Fortinet Technologies Inc.

There can only be one base that is set to sync level 1. Keep this in mind when configuring the FON-D72 in FortiVoice. Correct: Incorrect: The multi-cell network can be configured in numerous ways. Below are examples of multi-cell networks that maintain a strong synchronization between base stations: FortiFone FON-D72 User Guide Fortinet Technologies Inc.
The following table gives a general guideline on the degree to which certain materials will reduce signal strength: Material Degree of attenuation Example None Open space Wood Door, floor, partition Plastic Partition Glass Un-tinted glass, partition FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Avoid installing base stations in the direct vicinity of cable channels, metal cupboards or other larger metal devices. Creating a planning drawing Create a planning drawing to determine the placements of the base stations. Enter the building dimensions, identify hotspot areas and any sources of interference. FortiFone FON-D72 User Guide Fortinet Technologies Inc.

Building materials Degree of attenuation Metal Very High Concrete walls High Brick walls Medium Glass Now you can enter the preliminary placements of the base stations into the planning drawing: FortiFone FON-D72 User Guide Fortinet Technologies Inc.
Check to ensure that these placements are correct by taking measurements, as described in the Measuring signal strength section. Measuring signal strength Taking measurements can help determine where you may need to put additional base stations to have handover and synchronization. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
1. Temporarily affix the measuring base station in the planned position where it will be installed. 2. Establish a call between the two measuring handsets, observing the signal, until the RSSI reaches -80 dBm. Make note of this within your reference log. FortiFone FON-D72 User Guide Fortinet Technologies Inc.

The following image presents an example planning drawing: The following table presents an example of measurement log results (in dBm/100%) for the above planning drawing: Measuring Base A Base B Base C Base D Base E Base F point FortiFone FON-D72 User Guide Fortinet Technologies Inc.
3. Record this within your measurement log. 4. Measure for all planned positions of base stations that will synchronize with the first-level base station. The following image presents an example of planned base station positions: FortiFone FON-D72 User Guide Fortinet Technologies Inc.

With this example, a sensible sync level hierarchy would be: Sync Level 1: Base station A Sync Level 2: Base stations B, C and E Sync Level 3: Base stations D and F FortiFone FON-D72 User Guide Fortinet Technologies Inc.
M has been added into the planning drawing in the stairs: In this configuration, also measure the signal strength within the stairwell to ensure that the base stations can synchronize. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
2. Make sure the phone is properly registered with the phone system. 3. If your phone is configured as an external extension, check the network connection and firewall settings at the phone system location. FortiFone FON-D72 User Guide Fortinet Technologies Inc.
