Hi Kim Boll Jensen & Treg I remember responding to a similar question through Treg some time ago. The answer is that there are two versions of V.35 interface. The pin-outs and connector (type MRAC) do not change, but electrical spec of the I/O lines does. In the USA and Canada take care to ensure which type of V.35 system you are designing. All V.35 interfaces have V.28 control lines but the Hybrid version with V.28 and V.11 circuits is often used instead of the very low voltage (+ - 0.55v balanced) original V.35 signal lines. You may require two versions for global markets. (Study the V.35 changes made at red and blue book issue).

I know that a lot of new equipment still uses V.35 but have this standard been changed to another standar but still called V.35 ? Can anyone tells me more about the "life of V.35". Best regards, Mr. Kim Boll Jensen
