3 | 4 | laforge | h1. ISDN (and POTS) at CCC Camp 2023 |
4 | 1 | laforge | |
5 | @jolly and @laforge are planning to operate an experimental ISDN and analog telephony network at the "CCC Camp 2023":https://events.ccc.de/camp/2023 |
||
6 | |||
7 | The subscriber lines will be terminated using de-commissioned [[V5_Access_Multiplexers]] that were donated by telecom operators together with the "osmo-v5":https://gitea.osmocom.org/retronetworking/osmo-v5 protocol stack and "osmo-cc":https://gitea.osmocom.org/cc |
||
8 | |||
9 | This network will be provided for people to re-enact the good old telephony days, using anything as old as rotary dial phones, up to the 1990s ISDN experience. |
||
10 | |||
11 | So if you still have your old wired telephones or ISDN equipment in a basement, feel free to bring it along and hook it up. |
||
12 | |||
13 | h2. How to connect to the network? |
||
14 | |||
15 | h3. Types of interfaces |
||
16 | |||
17 | We can offer |
||
18 | * analog POTS ports, expsed as classic 2-wire "ab" interface according to German standards. |
||
19 | * ISDN ports using Uk0 interface, using 4B3T according to German standards |
||
20 | |||
21 | h3. What Equipment do I need to bring |
||
22 | |||
23 | For analog lines, you can connect any analog phone, anwering machine, fax, modem, etc. |
||
24 | |||
25 | For ISDN lines, you would need to bring your NTBA (to convert Uk0 to S0) and then any ISDN equipment like phones, ISDN adapters, PBXs, ... |
||
26 | |||
27 | 3 | laforge | If you only have ISDN equipment for S0-bus but no NTBA, we have a few NTBA around that we can lend you, as needed, on a firs-come-first-serve basis. |
28 | |||
29 | 1 | laforge | In addition, it is wise to bring sufficicent length of telephony wires so you can connect to the closest "Point of Presence". |
30 | |||
31 | 2 | laforge | h3. Where can I connect to the network |
32 | |||
33 | You would need to run some telephony wire (or CAT5, if that's all you have) to one of our "points of presence", where we will put [[V5_Access_Multiplexers]]. |
||
34 | |||
35 | We are planning to deploy those at *only a few* (2-3) "Datenklo" around the camp site. One of them will be in the vicinity of the PoC tent, the other locations are yet to be determined. |
||
36 | |||
37 | 1 | laforge | h2. What kind of services do you offer? |
38 | |||
39 | 5 | laforge | Our experimental analog + ISDN network will be interconnected with the "PoC/eventphone":https://eventphone.de/ so you should be able to connect not only with other users of the analog/ISDN network, but also the PoC DECT subsribers, as well as the c3gsm GSM subscribers. |
40 | 2 | laforge | |
41 | There _might_ also be connectivity with the [[octoi:|OCTOI]] network, but we are uncertain if we can achieve that. |

43 | h2. How to contact you |
||
44 | |||
45 | Contact details on how to reach us will be provided ahead of the camp. |
