I will be providing 24 ports of Analog Telephony from my tent to the immediate vicinity of datenklo D1.

To join in - turn up with a POTS phone (DTMF dialling is preferred - I haven't tested if pulse/loop disconnect dialling works but in theory it should do), and we will run a cable to your tent. A standard install will provide 1M of cable from the boundary of your tent, and a BT 431A type socket. If you have a phone that takes another standard plug for connecting into the network, please bring a converter (or the relevant socket if such a converter doesn't exist).

Phone installs will entail a cable running from "the exchange" (aka my tent) to outside your tent (if a nearby cable/DP doesn't already exist) and a small junction box on a stick installed, each can carry 3 lines, so one for you and two for others nearby. Once a DP (distribution point) is installed, a tail running from the DP with a BT socket on the end will be provided to the boundary of your tent. All you have to do is turn up with a phone. :)

The network is anticipated to be operational from mid-Friday until we get kicked off site on Monday, but this depends on me configuring the kit quickly enough. Access into the network is via a Cisco IAD2432-24FXS, and interconnects into the rest of the Eventphone network via SIP, so you should be able to make calls to/from the GSM and DECT networks. Obviously, no service level is guaranteed whatsoever, and no backup power exists for this equipment.


FAQ

My phone uses RJ11/anything other than a "BT plug"

Sockets will be provided with a BT plug. We can provide a bare copper pair should you wish to provide your own socket, or if you wish to use screw terminals etc. Feel free to contact me for wiring advice if you have something funky.

Is Pulse dialling supported?

In theory, yes, in practice this isn't something I've tested with the IAD2432-24FXS, so it may not work. Ports will need to be manually configured to support pulse as they default to DTMF.

Can I make calls to/form GSM/DECT extensions?

This is a planned feature - the IAD2432 supplying service will be interconnecting with the Eventphone network via SIP to make this possible.

Can you guarantee any service level?

Lol, no. It's a muddy field, expect bad joints, no dial tone and crosstalk, although we'll try to fix it if we can. It can't be worse than the service currently provided by britain's incumbent telco ;)
