brizee Posted April 2, 2009 Posted April 2, 2009 just a quick question, while changing round my phone sockets, i've trodden on the master totally destroying it. as a temporary measure i connected up a slave to see if it would would work. All works fine and i'm gonna replace it today. Am i right in thinking that the slave is lacking the capacitor? and what are the potential problems of this, I know its not right but why?
james.wilson Posted April 2, 2009 Posted April 2, 2009 without the master there will be nothing generating a ring signal (ie wire 3) so some phones wont ring. But they will dial ok. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
Lectrician Posted April 2, 2009 Posted April 2, 2009 without the master there will be nothing generating a ring signal (ie wire 3) so some phones wont ring. But they will dial ok. Some modern phones do not require the ringer to be connected (term 3), but this should still be connected. The large yellow capacitor blocks the DC line current, and allows the AC ring current to pass when the phone line is ringing. It is called a "DC blocking capacitor). The master socket will also have a surge arrestor and a resistor to facilitate line testing. Email : martin@askthetrades.co.uk
hpotter Posted April 2, 2009 Posted April 2, 2009 Thought if you wanted faster bb, dis the 3rd wire? (still need the master skt though)
james.wilson Posted April 2, 2009 Posted April 2, 2009 is that true? I thought a better filter helped (ie the bt face plate) securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
Lectrician Posted April 2, 2009 Posted April 2, 2009 On fringe lines where the line is too long, or is using old alu cables etc, then you can increase speed (or even then be able to connect!) by disconnecting the ringer if you have extension wiring in your home. There is a new Iplate filter which filters the ringer wiring and prevents you from having to disconnect the ringer. You cannot fit the Iplate with a faceplate filter though. Modern NTE5a's (last 9months or so) will have the I plate built into the back of the NTE (small cylinder approx 10mm dia showing on the rear). Disconnecting the ringer is a last resort. However, microfilters do provide their own ring capacitor do produce ring current for connected devices. I have been to many sites where disconnecting the ringer actually enables a connection to be established. Email : martin@askthetrades.co.uk
james.wilson Posted April 2, 2009 Posted April 2, 2009 see learn something every day. Didnt know that. Ill dis my 3rd wire tonight securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
hpotter Posted April 2, 2009 Posted April 2, 2009 Link below, abt 3/4 way down page "What's all this ring wire removal about then" http://www.rob-r.co.uk/other/UKphonecatwiring.htm
y-i-out-of-bed Posted April 2, 2009 Posted April 2, 2009 yeap remove wire 3 ring on bb as some filters dont block it so it lets the high frequncy adsl bounce around, some adsl filters have there own ring cap in them after filter, i took mine off my alarm filter and then fitted master after for other sockets, adsl taken before alarm filter no ring wire before alarm, tryed it with ring wire all the way and when phone pluged in bb droped so defantly true and speed barely got above 1meg removed and fitted master after filter how 7meg so defantly good pount use cheep tesco phone for test, newer phones dont use ring wire
Rulland Posted April 2, 2009 Posted April 2, 2009 Had my 3 at the master disconnected for nearly a year now-as soon as I did it my BB speed increased by nearly a meg!! . No probs with any of the phones all ring etc as they should!. Richard
