FCC Part 68 is the regulation formulated specifically for fixed-line telecommunication terminal equipment by the US Federal Communications Commission (FCC). All communication products sold in U.S. must comply with the requirements of this regulation.
Part 68 of the FCC rules mainly governs the direct connection of terminal equipment (TE) to the public switched telephone network (PSTN) and the TE must undergo the FCC Part 68 equipment certification process as per requirement, such as analog telephone, telephone voice, XDSL, VOIP, E1, T1 products that all are required to be certified to prevent harm from terminal equipment to the network communication. Currently, FCC has authorized Administrative Council on Terminal Attachments (ACTA) to oversee the management of certification services. For key testing standards, please refer to TIA 968-B.
For different TE, the test items are different. For commonly used ADSL systems, the main test items are as follows:
302(a) Mechanical Shock
302(b) Telephone Line Surge : Type A
302(c) Telephone Line Surge : Type B
302(d) Power line surge
304 Leakage current limitation
306 Hazardous Voltage limitation
314(a)(b) billing protection
308(b) 200Hz~3995Hz voice signal test
308(c) 3995Hz~4005Hz signal power test
312 ON-HOOK on-hook resistance limitation
308(d) 100Hz~4KHz Longitudinal voltage test
308(e) 4KHz~6MHz Longitudinal voltage test
310 Transverse Balance limitation
The FCC Part 68 regulation designated for the certification testing requires that the power source and the system undergo compatibility testing simultaneously. Test items that are power source-related include:
