¿ªÔÆÌåÓýFirst, let¡¯s get the details correct. ? The Internet is NOT going to fail. Just ain¡¯t going to happen, it¡¯s an impossibility because of the design. ? What CAN and WILL often happen is that YOUR connection to all or part of the Internet may fail. Or, the server that is hosting WebEOC may lose it¡¯s connection to all or part of the Internet. ? So, If you have lost your connection to the Internet, but A DSTAR repeater with an Internet connection and the High Speed Data module still has its connection, then by using an ID-1 on your side, you can get access to WebEOC. ? If the WebEOC server has lost its connection, then things are kind of the same, but actually different because the normal IP address and DNS record used to access WebEOC are no longer valid. Give a good networking guy a little bit of incentive, and this is not hard to fix. ? Or, you can bypass the Internet completely by using 2 ID-1s as an Ethernet bridge. There¡¯s a little bit of networking that have to be added to make it work, but it¡¯s a pretty simple process. ? Two ID-1s talking to each other, is essentially the equivalent of a half-duplex crossover Ethernet cable running at 100 kbps. You can hook two computers together, but you also have to worry about things such as IP Addresss and DNS access. ? I¡¯m pretty sure that I¡¯ve run WebEOC of an ID-1 through a D-STAR repeater.? No big deal. ? Also remember that the coverage of the High Speed Data is not as great as DV mode. A 300kHz wide 10W signal just doesn¡¯t do as much as a 6 kHz wide 10W signal. ? Ed WA4YIH ?

This can take place on the following items: 1) there is an ID-1 on the ip network that WebEoc resides on. 2) The ID-1 accessing the webEOC on the other end is also authorized ??? to access the network. (ip block is 10.x.x.x and static ip'ed AWAY FROM ??? the D-STAR Network ? The web server running the webEOC can or should have a second NIC and firewalled for all practical reasons, but firewalled in a way that port 80 or 8080 is only accessible from the 10./8 network or from another subnet like 192/16 or 192/8. That way the server has some for of protection of it's own. ? AS A LAST DITCH EFFORT, all the above would be a YES. As for it being done now...... Not here in our area.... so no. ? This probably could be tested state side in the US at the Georgia WebEOC corp. HQ if they took some interest into it... ?
