John, as I understand the Icom software it depends on an IP based transport network with one trust server, where the gateway servers connects to. I think it is not possible to build a mesh network with this version.
But I think you can build your own network with several ID-1 and simple routers, set up with small IP network segments and fixed routes between them. One small example: H3router_ID-1~ID-1_H2router_ID-1~ID-1_MCCrouter_ID-1~ID-1_H1router | | | | H3LAN H2LAN MCCLAN H1LAN In my example you have Hospital 3 not seeing the MCC, but Hospital 2. 2 and 1 can connect to MCC directly. The H3router needs two LAN interfaces with two separate IP networks. Between H3router and H2router is the same IP network. H2router needs 3 interfaces and 3 networks. The MCCrouter needs 3 interfaces and 3 networks. Every router needs static routes, where to find all the other networks. It should also be possible to run a tunneled network over all routers, but the ID-1 is only half-duplex capable as I know and this may cause bandwidth reduction. I'm not sure about this. You need to ask a better IP guru. 73 de Reiner, dh9fax --- In dstar_digital@yahoogroups.com, "aa2bn" <aa...@...> wrote: > ... > I'm involved with an emcomm project where several hospitals need internet-free backup data communications to a facility called the Medical Coordination Center (MCC). Some of the hospitals are close enough to the MCC that an airlink can be established with an ID-1 and a yagi antenna, the other hospitals are just too far away. Several ID-RP2C/RP2D units and ID-1s have been purchased (but not installed yet). It seems the RP2Ds would require an internet connection to move data to the MCC and if there were a regional internet outage (hurricanes are our primary scenario) that would render the network ineffective. > ...
