"you should check carefully, as the standards vary greatly from country to country"
Not only the standards, but also the legal requirements: In some territories it is ILLEGAL to connect anything to the PSTN unless you have been through the appropriate Approvals process; it may not be sufficient that your product just meets all the standards - you may have to have the right piece of paper from the right test lab to prove it! This has all been discussed many times before - you should use the 'Search' facility. Here's a few examples: 8052.Com Message Forum: RE: 8880 DTMF transceiver and Call Progress 8052.Com Message Forum: Legal & Regulatory Issues 8052.Com Message Forum: RE: telephone interface: and many, many more...! BTW: You can download the specs for the BT network free at http://www1.btwebworld.com/sinet/, and ETSI specs from http://www.etsi.org/ |
