Incoming Wormhole Identification?

[airam]

I'm doing a little research for a fanfic I'm working on.

Can the SGC identify what planet is dialing after a wormhole has been established? Or do they only know who's calling if someone from the other end identifies themselves?

Thanks.

theres no way to identify what planet is dialing in, unless the person who dialed from that planet tells you.

You cant tell who is dialling, unless you know who is dialling and where from, you can possibly set up audio/visual communications as seen in "First Strike" and many SG-1 Episodes(using a malp though).

Although if you think about it knowing the stargates communicate through a subspace network and updating locations etc, would it not be possible to estimate the region of space a wormhole has connected from? (probably not but worth asking)

they dont actually communicate through a subspace network, they communicate to update their locations in space every 200 years or so but thats by dialing each other and transmitting the info through the wormhole and then the recieving gate does it to another gate and so on and so forth untill every gate is updated. the gates have no means of direct subspace communication.

not to contradict you but um stargates open a subspace channel between the two of them. the DHD then transmits the updated data. So yes the DHD's do use subspace communications for the periodic updates. however you are correct that there isn't a secondary transmitter between DHD's, and require the wormhole for such communications.

in the form of a wormhole, yes. the dhds do not have any means of subspace communication like we think of it with like ship to ship communication. the only time the gates communicate is when they have a corrolative update every 200 years and when that happens every gate dials like 2 other gates and then those gates dial 2 other gates and so on and so on untill every gate has been updated.


it has NEVER been shown in the show where 1 gate opens a subspace connection to another gate unless its in a form of a wormhole.

SGC has never exhibited any means how to identify from what planet a gate is comming from:
It is evidenced:

SGC received a message from people pretending to be the Tokra butit actually came from Apophis back in Season 2. So he can doom Earth at the hands of Sokar.
In the otherside early season episode someone was dialing to earth 3 times it was only after Carter adjusted the receiver that they learned it was from that Purist race who needed heavy water to fuel their tech
In Redemption ANubis attacked earth with the weapon that blows up stargates we don't know where it was comming from Bratac had to dial every planet controlled by Anubis to get there.

SGA the Last Man Chuck said it is Col Shepard's IDC not the planet where Shepard disappeared from.
In the more recent episode of Prodigal they read the IDC not the planet where the IDC came from.

I suspect the Ancient version of the Dialing device can identify where the gate is comming from since it stores the gates dialled into it but is never been shown.

to the op:

With an Atlantis style set-up it is possible to tell either a) that an incoming wormhole is coming from earth, but more likely b) that an incoming wormhole is extra-galactic in origin (meaning, not coming from the current galaxy).

As far as identification more precise then that, the closest we've seen is either identification after wormhole establishment, or requiring the dialling party to enter a code prior to wormhole lock otherwise the dialling party will be redirected to an alternate site.
