 i assume 6 your not using tsi via a modem or a direct leased line etc. Times change and I think pstn for anything is past it least of all something possibly important 

 

I would argue that's completely different a modem has speed limitations. If a modem could do broadband speeds without having to have the line engaged it may still be in use.

There are a good few companies that still prefer fax for example. The time to be received is similar to an email so it's still fit for purpose.

Must admit I was using a fax machine myself until it packed up a few weeks back & never had any complaints.

I use the test um lil buttie, it has dsl indication and a screen with onboard dtmf decoding, cli, line voltage, line current and polarity indication. tbh though I dont use pstn for intruder alarm signalling but it is still very prevalant in warden call and medical alarm signalling, and the dtmf decode has been very handy on a number of occasions. I bought a few when comtec were having a clearout at around £13+vat

Thanks, will check it out. I've got the test-um high power toner & probe kit, that's been a really good bit of kit.

Sparkies look bemused when we use a prob and toner kit , then realise why nothing is labelled , easy to find with that

Yep certainly gets some funny looks. Strange how many ask to borrow them, once they see the kit in action.

Used to have the ideal kit, but that went at the same time as the butt phone.

 

The test-um is great for bigger sites as well.

In case anyone is interested, the tone generator is the TG200 & the probe is the TT100. The generator can apparently send a signal up to 2Km, never tried it at that but certainly works up to about 700m.
