Event setup

BornHack

The VG224 has 24 FXS lines, which I am splitting in two parts: 14 are going to the left side of the patch panel, 10 are going to the modem bank. At most 10 patch panel ports can be used simultaneously for internet connections.

The Asterisk box should be connected to the POC system, it is possible to have in and outgoing connectivity to the DECT network as well.

There are some modems as well. If you want to connect your own computer to the internet, this is possible as well.

Ansible -> vg224

UART

The modem bank has 16x female DB-25 connectors. These should be connected to a dial-in server. How to connect them?

PCI(express) card, maybe StarTech stuff?
USB hub with cheap USB FTDI/CH340 stuff
something else?

Trunking

Bring your own Ethernet cable, we can probably make a trunk to the other side of the assembly hall, but this require crimping cables and such. And maybe NOC does have an opinion on this, needs more investigation.

Todo: buy crimping equipment and RJ45 plugs

37C3

At 37C3 I had great plans, but it failed because of multiple reasons. Lack of time during the event and a broken power supply of the dial in server. And not enough preparations. we had vintage ThinkPads & telco assembly registered. Better luck next time.
