Hi Asterisk Community, I have a development with a TDM11B in it. I am trying to connect this to a exchange line as well as a UK telephone and are looking for some pinout information for the FXS port. Is it the centre 2 pins that at the tip and ring. I have been digging around the Digium site but cannot seem to pick up this info. Any help appreciated. Thanks -- Gary

I am assuming that in the UK, you use the same connector as we do in the States.. :-) Robert

An rj11 also can be used and fits the socket fine by design. In that case its the middle 2 pins (2 and 3). If you are in the UK you will know about the UK three-wire system for premises wiring. Some UK phones may not ring when connected to a TDM board; if that happens you need to go to Maplin and buy the RJ11 plug to BT socket adapter that INCLUDES THE RINGING CAPACITOR. Steve
Thanks Steve most helpful, Yes I am in the UK and we have master and secondary sockets for implementing ring. Master sockets have the ring Capacitor and secondary sockets do not, where it is designed that the ring voltage is already supplied on the 3rd pin. I am attempting to get my first asterisk server up and running so this is a learning curve.
