| 468322 | 2006-07-04 09:19:00 | How long have these been on sale? The splitter has been restricted to Telecom installers in the past. I have no idea - i just went to the local electrial store and asked for one. |

| 468323 | 2006-07-04 09:24:00 | Telecom has probably screwed its contractors down to a fixed price per incident. If they find some non standard bodge up that takes more time to sort thasn usual, they'll cry foul. the last time i talked to a contractor they where only getting paid something like $10 a call out. if it takes 1/2 to drive out, 1/2 hour to fix then they are only on $10 an hour pay :( then if it takes an hour ti fix because of some handymans wiring ...... |

| 468324 | 2006-07-04 09:25:00 | Not trying to hijack the thread, but hope the heading is general enough to take advantage of the experts here. . So - A couple of very basic questions from someone trying to get her head around the principles of installing Telecom's cheapest broadband - (1) Is a splitter the same thing as a filter? If not, what is each for? (2) What exactly is being "filtered out"? The telephone connection or the computer connection? For example - If a house has 5 phone jackpoints, but would use only 2 of them for broadband, what filters/splitters are needed where? As you can see, I'm getting confused (being a technical ignoramus) between installations at the point where the phone line enters the house & what's needed at the jackpoints. And an answer to those questions would fix that - in theory anyway.. |

A filter would go on each phone appliance that used the phone line. And you cant use two BB connections at the same time unless they are both on separate lines. Come to think of it. having 5 (or was it six) devices means that TC recommend a separate second line for the broadband. |

| 468326 | 2006-07-04 09:42:00 | The term splitter is rather a misnomer, it is a filter that passes the low frequency analogue audio voice phone signals. ADSL is high frequency, and the broadband modem is connected directly to the phone line, it doesn't go through the filter. So when a 'splitter' is fitted by Telecoms contractors at the inlet junction box all the phones have the high frequency filtered out and only get the low frequencies. If you do a self install, individual filters are plugged in at each phone jack point that have phones, so the phones are filtered. The modem is not filtered, it is plugged into a jack point through a double adaptor if there is also a filtered phone on the same jack. To make things awkward some filters have 2 sockets, one for the modem which is straight thro', and one for the phone which is filtered. That's why some people think the modem is filtered. |

| 468327 | 2006-07-04 09:51:00 | Only 1 broadband line envisaged, bob. And only one computer. But there are 5 rooms with phone jackpoints already. The idea is to be able to use the computer in 2 of them - but only one in use at a time. But any of the other jackpoints should be able to use the phone when the comp is on. P.S. Just found your answer, Terry Thanks so much. Looks like what I needed. |

| 468328 | 2006-07-04 09:59:00 | That would be ok as long as you are prepared to move the modem with the computer when you change rooms, and you'd plug filters into each jack point. Rather expensive with 5 phones, they're about $20 each. The other thing to check up on is whether the phone jack point are the older 3 wire systems that had a separate ringer wire. ADSL does not like these, and if you have them, they should be replaced with 2 wire jack points. Edit: of course if you dont have 5 phones you dont need 5 filters. If you moved a phone to another room, you'd move the filter with it. I also forgot to say with the "full telecom install", a separate connection is put in for the modem, the phone lines are not used for the modem as they are filtered. |

| 468329 | 2006-07-04 10:11:00 | Yes, they are oldies, Terry. (Everything in this house is an oldie, I fear) So it's all looking a bit pricy & a bit complex. I could give up some phone jackpoints without suffering, but I might just sit tight with what I've got for a while. Winter has enough nuisances as it is... Another P.S Ah, now that I've read your edit, it might be a different ballgame. (Thinking symbol) |

| 468330 | 2006-07-04 10:32:00 | To expand- Extra jackpoints were installed yonks ago for my older generation (Phone availability in several rooms) I know their wiring is old-style . But I don't use all of them now, so could give up 2/3 easily . . I own only 2 (elderly) phones & as I'm considering buying a new cordless model, could make do with only one . |

| 468331 | 2006-07-04 10:56:00 | Not trying to hijack the thread, but hope the heading is general enough to take advantage of the experts here . . So - A couple of very basic questions from someone trying to get her head around the principles of installing Telecom's cheapest broadband - (1) Is a splitter the same thing as a filter? If not, what is each for? Yes, just the physical configuration differs . A couple of years back I wrote full "How to" for installing a plug-in filter as a splitter, if anybody cares to look for it . (2) What exactly is being "filtered out"? The telephone connection or the computer connection? The telephone . The DSL modem must connect to the "naked" phone line . For example - If a house has 5 phone jackpoints, but would use only 2 of them for broadband, what filters/splitters are needed where? Filters on the three jacks with phones, nothing on the two that supply broadband only; or one splitter at the incoming phone line with the splitter output going to the three phone jacks only (they have to be isolated from the DSL side of the system) . The two broadband jackpoints are fed direct from the incoming phone line, taken off before the splitter . The basic principle is that all non-dsl devices (phone, fax, answering machine, dial up modem) must be fed through a filter, but the dsl devices (modem or router) should be connected direct to the incoming phone line without any form of filtering . For best result it is also desirable to convert the entire phone system to the new two wire system, which requires replacement of all phone jackpoints . The new type has a large 2 embossed in the bottom right corner . Telecom will not guarantee full dsl performance on the old three-wire system, which may explain why so many people get lower performance than they expect . It is in their written specs for dsl services . The old three wire system can (will) unbalance the line, allowing noise to interfere with the signal and cause speed losses . Similar problems occur if you use long phone extension leads to feed your dsl modem from a distant phone jack . Cheers Billy 8-{) |
