Just completed the disassembly of another two Siemens EWSD digital telephone exchanges, which are now in a truck on their way to the Telecom Museum Dresden (Fernmeldemuseum Dresden). Largest time sink was untangling the hundreds of cables (mostly with proprietary Siemens connectors).. #retronetworking #telecom #ewsd #isdn
…If the destruction of the #EastWing is a shock, the #money that’s paying for it might be even more of a #scandal. The #WhiteHouse, eager to assure Americans that their tax dollars have not been diverted for a #vanity project, has emphasized that the #ballroom is being financed by individuals & major #corporations. Instead of going through a process to obtain & disburse federal funds, #Trump simply asked companies his admin is supposed to be #regulating to write checks [ #bribery / #extortion].
The list of donors released by the #WhiteHouse includes the usual deep-pocketed #Republicans, such as #casino magnate #MiriamAdelson & private-equity mogul #StephenSchwarzman, but also a host of companies whose leaders have huge incentives to maintain good relations with an often vindictive head of state. They include #telecom giants & the #railroad giant Union-Pacific—which needs the #Trump admin’s sign-off on a proposed $85 billion merger with Norfolk Southern.

Some more pics of cable mess requiring untangling of one of the two EWSD exchanges. #retronetworking #telecom #ewsd #isdn

Another telecom outage in Los Angeles... this time they're blaming "multiple" fiber optic cables vandalized.

Hmm, interesting, wonder who funded this absolutely massive cache of cell phone devices and SIMs?

alors bon avec un forfait illimité en fait je m'en moque (côté facturation) mais ceci explique pourquoi je mesuis fait "massacrer" par Orange lors de mon dernier envoi de SMS sur un numéro de portable ... suisse (SMS complet pour covoiturage)
5 # apeupresque boum dans ma face !
Si quelqu'un du monde des #telecom peut confirmer c'est OK

Hé ben, nous ferions bien de nous demander dans quelle mesure nous souhaitons être complices de tout ça. Les enjeux sont bien au-dessus de nous, nous ne nous rendons même pas compte. Changer les choses passera forcément par mettre un bon coup de pied dans la fourmilière. Arrêter de jouer ce jeu mortifère d'autant que les terres rares et la pollution liée n'ont pas été abordés ici

This is something you need to read in order to believe
subject: VoLTE
provider O2 UK
nightmare: infosec
Enormous. Outragerous are some of the words I would use. Take you time to read and learn because they are not the only culprits on the planet with such bad data protection practices
Excerpt
>>
Quite quickly I realised something was wrong. The responses I got from the network were extremely detailed and long, and were unlike anything I had seen before on other networks. The messages contained information such as the IMS/SIP server used by O2 (Mavenir UAG) along with version numbers, occasional error messages raised by the C++ services processing the call information when something went wrong, and other debugging information. However, most notable were a set of five headers near the bottom of the message:
SIP Msg
...
P-Mav-Extension-IMSI: 23410123456789
P-Mav-Extension-IMSI: 23410987654321
P-Mav-Extension-IMEI: 350266809828927
P-Mav-Extension-IMEI: 350266806365261
...
Cellular-Network-Info: 3GPP-E-UTRAN-FDD;utran-cell-id-3gpp=2341010037A60773;cell-info-age=26371
Synthesised excerpt of IMS signalling message for demonstration; not a genuine IMEI/IMSI/cell ID.
Two sets of IMSIs, two sets of IMEIs, and a Cell ID header. How curious…
Sure enough, when comparing both the IMSIs and IMEIs in the message to those of my own devices, I had been given both the IMSI and IMEI of my phone which initiated the call, but also the call recipient's.
