We are moving into a new office at a unit that has not been occupied before. However it was built and wired in 2008.


We have been installing the network wiring while we await the 5-10 working days required to get the internet connected.


A PDL BT wallplate connector - specifically a 617M2 - is being used to wire to the modem and there is an internal ETP installed - a grey box with a 5 pair connector marked B10014.


I was interested to note that nothing seems to have any capacitors or resistors which I had thought were used to terminate or supress noise. If installed 'as is' we would have 2 wires going straight from the street to the modem. Is this correct or are some bits missing?

Nope thats all good, a modern 2wire system has no bell capacitor, and the test resistor and cap network was removed from sockets years ago. There is no need for any filters or suppressors etc as these are provided on the line card/mdf at Telecoms end.

Obviously if you have POTs and DSL on the same line you should have a filter to seperate them.

Thanks Cyril,


We are just getting naked broadband and using voip phones - Linksys SPA942. We have been using them for a couple of years with no problems - except when we had a power cut!


Actually, that reminds me I was going to look at PoE for the new setup. The modem/switch, etc will now be running from the UPS so i just need to power the phones - although I suspect the battery won't last long.

They are still there, just inside the phone.
