hastings Posted March 3, 2008 Share Posted March 3, 2008 A colleague and I attended a presentation run by Southern Monitoring Services last week regarding 21CN and it's implications. Most of it seemed to be a sales pitch by CSL (DualCom), Emizon21, Redcare and WebWayOne. There were a few interesting parts regarding compatability with digital communicators, the BT website mentions that during the switch over, line fault activations will occur, but should only happen once. South Wales is the 'test area' for 21CN in the UK apparently so you may well be getting more problems there. There may be possible problems with some digital communicators after the switchover, they made the comparison of trying to connect a digi com to the 'free' phone line that you get on most home routers now. As most of you will know, you can plug a normal telephone into this socket and make a voice call, but if you try to run a fax or credit card machine or digi through it, it doesn't always work. Our ARC uses 0870 as a prefix for it's reciever numbers, other changes to BT services may well require a change to 0844 as a prefix instead. (loads of phone numbers to reprog on routine maints then!) My colleague and I both left the presentation with a bit of a headache ! More problems to follow I'm sure ! Link to comment Share on other sites More sharing options...

IPAlarms Posted March 3, 2008 Share Posted March 3, 2008 the BT website mentions that during the switch over, line fault activations will occur, but should only happen once. There's that word again - SHOULD South Wales is the 'test area' for 21CN in the UK apparently so you may well be getting more problems there. There are only 8 people that live in South Wales aren't there. Not much strain on the network there then. There may be possible problems with some digital communicators after the switchover, they made the comparison of trying to connect a digi com to the 'free' phone line that you get on most home routers now. As most of you will know, you can plug a normal telephone into this socket and make a voice call, but if you try to run a fax or credit card machine or digi through it, it doesn't always work. Finally - we are getting to the nitty gritty. More problems to follow I'm sure ! Nooooooo - BT have advised the industry that everything SHOULD be fine. Any word from NSI or SSAIB yet ? - Surely there's an opportunity for them to make some money out of this.

arfur mo Posted March 3, 2008 Share Posted March 3, 2008 just found a bullet in from Gardtec, they have been trialling there communicators which all operate ok. the audiable signals will be multiplexed, so i think the cure is to extend the tone time windows to overcomes the delays in switching. regs alan If you think education is difficult, try being stupid!!!!

arfur mo Posted March 3, 2008 Share Posted March 3, 2008 but then it doesnt comply with regs (so I`m told) BT know the tests are flawed hi Angus, are you saying GT's digis are not compliant if so any idea why? or did you mean slowing/extending the tx rate because it would be seen as a slightly backwards step, more like the older 'slow format'. would be odd as we are talking say 1 - 2 seconds more delay at most, but better chance of a successful communication 1st time over the 'media' path being supplied. regs alan If you think education is difficult, try being stupid!!!!

arfur mo Posted March 3, 2008 Share Posted March 3, 2008 surely the simplest work-a-round is for bt to have in their software a 'step' which prevents multiplexing for devices which issue an 'enquiery' tone? would save all this hassle at a single stroke. regs alan If you think education is difficult, try being stupid!!!!
