DS1000 Protocol? Connection spanning a network?

[Cypris]

I have a client with a DS1000 Phone System and DX7NA-12TXH phones. My client has expanded to a building that is down the block and is connected to the original building's computer network with a Long Range wifi solution. Someone (not me) set up Grandstream HT503's which lets the remote building have phones with basic features, i.e. home phone services but we need to get the functionality of the phone system over to the remote building. the DS1000 says it has digital and analog stations but it does not say what the digital IS. Does anyone know what the DS1000 speaks? Also, and this would be a shortcut I guess, does anyone know of a device like the HT503 but meant for this kind of phone network?


thanks!

I guess "Digital" is just a type.. so the question is how do i get this phone to work over LAN, more or less like how the HT503 does it.. but for Digital Phones.
