London public transport sign rebooting

Seems to have a modem in it. After about 5 minutes it managed to get an IP, which was partly masked (number changed to “xxx”).

    Is there any additional info known about these devices? OS?

    Those devices tend to have a non-x86 CPU, flash storage, a ROM with embeded OS (custom linux/(net)bsd variation) and a gprs modem for data retrieval.
