In the event of loss of synchronization, the DECT IP base station stops accepting calls once all ongoing calls that were being conducted on the asynchronous DECT IP base station have ended and then it re-synchronizes the asynchronous DECT IP base station.

The two lower DECT IP base stations are synchronized over LAN because a solid fire door prevents DECT-based synchronization.

Make sure that adequate lightning and overvoltage protection is provided for the cable feeder into the building and the DECT IP base station • Radio propagation Radio propagation is negatively influenced by A31003-C1020-S100-03-7620, 12/2017 OpenScape Cordless IP V2, Service Documentation...
The different levels of radio propagation give rise to various scenarios in which radio cells are formed: • in the open with visibility • industrial sites with reinforced concrete buildings and buildings with metal facades A31003-C1020-S100-03-7620, 12/2017 OpenScape Cordless IP V2, Service Documentation...
For example, in the case of a base station installed on the southern side of a brick building, the range limit on the northern side would be attained immediately or after just a few meters, owing to the insertion loss. A31003-C1020-S100-03-7620, 12/2017 OpenScape Cordless IP V2, Service Documentation...
These ceilings are dimensioned based on the purpose of the building, for example, – single-family residence – apartment building – office building – theater and so the insertion loss a also differs accordingly; see Table 4.

Concrete walls cause similar conditions to those described above. Elevator shafts and stairwells must therefore often have their own base station if they are to be included in the OpenScape Cordless IP range. A31003-C1020-S100-03-7620, 12/2017 OpenScape Cordless IP V2, Service Documentation...
Assuming that the distribution of handsets in buildings will be fairly uniform, additional base stations should preferably be installed on the floors above or below the minimum required base stations (see Figure 11).
