The SCP is used for communication between the N870 DECT Manager and the N870 base station. Numerous mechanisms of the DHCP protocol are reused in this. In this case, the N870 DECT manager acts as an SCP server and the base stations as SCP clients. Due to the fact that a "common broadcast domain" is needed, SCP cannot be used between different subnets or sites, which are interconnected by means of a VPN. This is due to the protocol being used and the layers: e.g. VPN (OSI) is layer 3, the broadcast domain, however, is layer 2. Lower layers are not just able to use higher layers. In this instance, each subnet requires its own separate, independent DECT manager.
You must install the DECT base stations in the same subnet due to it must be in the same broadcast domain. |
