Every home should have one
on 14 May 2011
An excellent piece of electronics that every telephone Master Socket should have! If you replace this faceplate at the Master Socket (commonly referred to as BT socket), it means you do not need [the dangling!] ADSL filter on every telephone extension socket -- meaning tidy wiring throughout the house, i.e., a single filtering is done at the Master Socket and extension sockets will be pure voice lines free of the ADSL data signals (just what used to be before the Internet was born).
Some useful tips: (1) if you're using a telephone extension, [if possible] avoid running pins 3 and 4 (modern telephone equipment don't need these -- only run pins 2 and 5 and you should note an improved data speed as compared to connecting pins 3 and 4; (2) if you are running an ADSL cable from a Master Socket (pins A and B on the faceplate) over a few metres such as to upstairs, avoid using flat telephone line (such as CW1311 type), instead use twisted pair telephone line (CW1308 type also used in alarm systems).
Together with the tips mentioned, I noticed a significant improvement of internet data speed with this faceplate. The ISP test speed at Master Socket (with all wiring disconnected and test run by ISP) was just under 6 Mbps but I could only get around 3.3 Mbps as my router was located upstairs. With the filtering and tidying up achieved with the Tamar faceplate + doing away with pins 3 and 4 on extension lines + using CW1308 type twisted pair for connection to my ADSL router located about 15m away, I now get the full test speed of around 6 Mbps. Very hard to apportion the contribution of this ADSL filter in speed improvement (without proper measurements) but well worth the money even on aesthetics alone (getting rid of the dangling ADSL filters), and in addition no doubt that doing the filtering job at a master socket has its pluses of keeping the ADSL signal clean and isolated thereby improving the data rate.
