Can someone please direct me to any information that assists in the linking of ID-1's and Data Repeaters together, for example how do I link "say" 3 ID-1's to two Data repeaters and get them all talking to each other in a network?

We use Linux appliances behind our RP-1D modules to provide one to many and any to any support for ID-1s.? The (simplex) “repeater” modules are happy to accept sessions from any number of ID-1s to the Ethernet, and DNAT lets us assign a unique IP/subnet to each ID-1 attached network.? (ID-1s are Ethernet bridges).? Then the ID-1s can all reach hosts on the repeater Ethernet, and talk to each other via the repeater.?

We are not fans of having databases or applications at repeater sites, so we have the applications remote on their own ID-1.? We treat the DD repeaters essentially as satellites- you uplink and downlink to them.

We have tested under real life public service conditions one uplink and three downlink ID-1 radios per repeater.? And we have run up to three ID-1s at a time on different frequencies in our data trailer.? Each ID-1 can support a small IP subnet- several laptops etc.? ????You need to be careful to not saturate the links, which are about like dial up Internet.? Rich media, esp. bidirectional streaming media is not a good idea.? Basic web apps like data entry and query work like a champ.

We use the Ubiquiti gear + mesh networking protocols ?on 5G to link the Linux appliances/repeater sites- so the ID-1 is a high powered user access station.? This has been ideal when you need 12-20 mile hops in high ambient RF /802.11g areas like big public events.

The Icom modules for DD are not repeaters.

The ID-1 presents an Ethernet interface to plug into. ?What it does is put any Ethernet traffic it sees on its Ethernet port to RF encapsulated in a D-STAR packet.

When the D-STAR packet arrives at another ID-1 (Simplex/Local) it looks at the header to see if it's addressed to it, unwraps the Ethernet packet an puts it out the Ethernet port.

If it goes to a RP2D (DD Module) it is directed to the controller, which can switch it to another module (based on RPT1/RPT2) or send it to the gateway. ?When it arrives at the gateway it looks at the UR which will:

Send the traffic to a remote D-STAR radio (ID-1) if the UR is set to a station (e.g. ?WF7R ? A) through the last remote gateway where that station was heard.

or

If your is set to the callsign associated with the gateway, it will unwrap the Ethernet packet and send it out the Internet facing Ethernet port, where if the IP address is on the public Internet the router will NAT it out to the Internet.

So on the RF side, its basically all simplex (though going through the RP2D you set it to RPS which is repeater mode with 0 as the offset, there's a bit in the D-STAR header that needs to be set) -- just treat it as such. ?(Line of sight for the most part.)

Data Repeaters actually modules) are going to give you access to the Internet as part of the standard Icom repeater stack. Implementing the Data modules in a private network is a lot of work with minimal, even negative return.

?

If the repeater has data module, then the ID-1s can talk to the Internet. Many Internet applications such as Email work great. Don’t expect high-speed applications such as playing movies or most VOIP solutions to work.

The Data modules, since they are simplex, do not allow 2 ID-1s to talk to each other.

?

If you have 3 ID-1s and they can all hear each other, then they will function as a Ethernet hub with three ports.

I suspect I need to chat with you offline. Sounds like you've implemented something I've been thinking about and that means I shouldn't have to reinvent the wheel! This is cool.

Hi Dave,
  I bought two ID-1's to play with.  Since the ID1's are merely a network bridge, I tried to connect them to each other without going through a DSTAR network and it worked.   I found that I was getting about 96k baud out of the 128k theoretical.  Good enough for FTP, email, casual web browsing, etc.   Not good enough for running a DVAP or VoIP or any video.  But its cool just the same.

Good info below!? Questions at the bottom:

So on the RF side, its basically all simplex (though going through the RP2D you set it to RPS which is repeater mode with 0 as the offset, there's a bit in the D-STAR header that needs to be set) -- just treat it as such. ?(Line of sight for the most part.)

I'd like to try sending anything via our local (K7LWH) RP2D module, but the questions are general.? I've sent up my LAN (172.x.x.x) gateway's routing table to route all accesses to 10.x.x.x to the internal side of an old LinkSys BESFR41 router, with the external side of the router connected to my ID-1.? The external side of the router is configured to use one of my D-Star registration-allocated IP addresses (10.108.78.227).

Naturally, I'd like to PING something and get a response back.? When I point the ID-1 at K7LWH__A (DD) with UR="CQCQCQ" and PING 10.0.0.1, I see the radio transmit, so all that works.? However, I don't see a response back (on the radio).? There are often 23cm issues with that site.? So, my questions are:

? #1.? Is there a way to see if a given DD module is even on the air?? The K7LWH page is no help (because it's oriented to DPlus DV traffic, I assume).? There's no indication on the page that K7LWH is hearing AE7Q___N (note that the "Last Heard" data is for the K7LWH/A DV module, not the DD module).? However, I don't know if that page tracks DD modules (I would hope so, since callsign routing is supposed to work in DD mode).

? #2.? If a local DD module is on the air, is there a good local (ie, in the gateway) 10.x.x.x IP address to use for testing (eg, PING)?? That would nicely allow for a local test.

? #3.? Once I get local traffic working, the next task is to pick another DD repeater site, and try to send traffic there.? I assume I'd then use callsign routing (or repeater routing) to get the traffic there, and then PING an appropriate 10.x.x.x site there.? It would be nice if there was a 10.x.x.x IP address on the DD network, that simply replied to PINGs, or even better, had a "here am I" or echo response like a trivial web page ...

? #4. I understand from John Hay's eMail above, that there's a similar protocol to getting traffic through the ID-1 directly to the Internet (eg, UR set to the gateway callsign), but I understand that's discouraged or restricted due to legal issues.

? #5. Finally, callsign routing:? If I use repeater A in DD mode, and then use repeater B in DV mode (using the same MyCall), obviously callsign-routed DV traffic to me from someone else will now go to repeater B.? My question is, where will callsign-routed DD traffic to me go?
