Dear All, Is an ISDN U Interface considered a TNV-3 or a TNV-1 for North America (US and Canada) and why? I rteckon it is TNV-1 since voltage levels do not exceed SELV levels. Please confirm.
For Europe, the ISDN U-Interface is a TNV-3. Looking forward to your responses. --------- This message is coming from the emc-pstc discussion list.
