The usage of the SCP protocol makes the N870 DECT base installation very easy but also has it limitations.
When using different Subnets, the DECT base stations could not reach the DECT manager to make the first connection as the switches block the SCP protocol. The network of the customer would need to be re-configured or you would need to install and Integrator and DECT managers.
In an upcoming software, it will be possible to install a DECT base station in a different subnet.
To get this working, you first need to be sure that your DECT base-stations are updated with the firmware that supports this feature. For this you can first install the base-station in the same subnet, let the Integrator/Manager update your base-station and then place in the other subnet.
The following changes are made to support this feature.
- By default a DECT base is now pre-configured to use DHCP
- The DECT manager joins a pre-configured multicast-group (220.127.116.11 i.e. listens to multicast-traffic)
- When base in different subnet gets IP from DHCP it is now capable to send its "Discover" also to the multicast-group.
- When those multicast packages are routed to the other subnet, the base can be "seen" as usual in the WEB-UI and can be accepted/configured.
The switch/router MUST be configured to forward those multicast messages between the different subnet's. As we are not the experts for your used switches, you need to configure this yourself, we can not support you but only document examples we received from our customers. Below we will document some switch configuration examples, documentation is ongoing.
