Hello esteemed colleagues: I have a customer insisting that Germany has a requirement for 14dB Return Loss for non-voice telephony analogue terminal equipment in spite of the recent passing of CTR 21. This particular case is a V.90 (56K) modem. I figure either:
1) they don't know what they are talking about (as CTR 21 is a CTR and it specifies 8dB from 300Hz to 4kHz, and 6 dB from 200 Hz to 300Hz) or 2) I don't know what I am talking about, or 3) this is something particular to V.90 (56K) modem requirements that is not harmonized that I don't know about. Is 14dB required for 56K? And if so, is it an industry standard or a legal standard? Any thoughts on this matter? I thank you all in advance for your assistance. Mel Pedersen Midcom, Inc.
