During our [[SS:S|SimSig Sessions]] voice communication will be provided by the '''Railway Operating Centre''', or '''R.O.C.''' (pronounced: ɑːr əʊ siː). The ROC allows easy communication between [[SimSig:Signaller|Signallers]] and [[SimSig:Service Controller|Controllers]], breaking down each signalling area into their own channel. The ROC also allows private calls to be made between two users as required.

The ROC is a web app that will switch users between different [[Discord]] channels depending on a number of factors. To use the ROC, and therefore to be able to fully communicate with all participants during a Session, a user must join the [[On Our Lines]] Discord server, and request the [[Discord#Roles|SimSig role]]. Once this is done, users can login to the ROC with their Discord ID, unlocking its functionality. A Windows build is availible to [https://github.com/ElaTheDeveloper/OOL-SimSig-Electron/releases/tag/v.10 download here].

Please note that ROC is still in it's ALPHA stages, and is slightly unstable and has some bugs. ROC is an open source project released under the GPL-V3 licence. It's repository (and where you can contribute) are avalible here on [https://github.com/ElaTheDeveloper/ROC its GitHub]

ROC can be used outside of a SimSig session, however panel names cannot be adjusted and no support is given to users outside of the official sessions.

== Basic Usage ==
To enter into the ROC's system, you first must join the {{Discord|on-our-simsig-lobby}} voice channel on the [[Discord]] before heading over to the ROC in your browser.

Copy your Discord Username (click on your name next to the settings cog in the bottom left of Discord) and paste it into the box. Click the Join Game button. It must include the discriminator (the # followed by 4 numbers).

You can set the panel you are working in the top right. Type in your panel name and click “Set Panel”

== Electron App ==
The Electron app can be downloaded from [https://github.com/ElaTheDeveloper/OOL-SimSig-Electron/releases/tag/v.10 GitHub]. The source code is also availible there. The Electron app is merely just a Chrome window, minus all the decorations. It just loads up the ROC webpage but allows you to have it in your taskbar.

Please be aware this is currently untested. It may not function exactly like the Chrome browser and therefore may have issues. Preliminary tests indicate there is no issue. However, do not expect much support if bugs are encountered.

Currently only avalible on Windows, however if users wish to build for other platforms, please do. The source code is avalible [https://github.com/ElaTheDeveloper/OOL-SimSig-Electron here].

== Compatibility ==
Here is a compatibility chart of web browsers that ROC works with. Please note that testing takes place on the latest browser verison only.

==Known Bugs==
There are currently a number of known bugs present on the ROC; it is beta software and its development is ongoing.
*Sleep/Screen locks: Ensure you leave the tab/window/tablet open without screen lock/auto sleep enabled. It will kick you if your device locks and you will have to rejoin from the lobby. This is a websockets thing. Basically don't let it unload.
*It is possible to call one's self. Please just reject yourself if you call yourself. It won't cause any issues.

''Known bugs will soon be migrated to an issue tracker; in the meantime, please do add any discovered and confirmed bugs to the [[SimSig talk:Railway Operating Centre|Talk page]], signing them with four tildes (<nowiki>~~~~</nowiki>).''
