Computer Sciences Laboratory Xerox Corporation Palo Alto Research Center Palo Alto, California 94304 415 494-4477 XEROX November 8, 1983 Mr. Wm. H. von Alven Telephone Interconnect Manager Common Carrier Bureau Federal Communications Commission 1200 19th Street NW, Room 304 Washington, DC 20554 Re: Xerox CSL-8308 Voice Terminal continuing quality assurance Dear Mr. von Alven: The quality assurance manual for the CSL-8308 is attached. The 8308 is intended for applications in office systems research inside Xerox, While at this time we do not expect to manufacture more than one batch, it is possible that some additional units will be constructed in the future. If we do make more, general quality will be assured by 100% functional testing according to the attached document. Testing specific to FCC part 68 will be through three routes: Functional testing The test procedures include checks intended to verify proper signal power limitations (68.308). Component testing Component testing procedures include checks intended to verify compliance with the Leakage (68.304) and Hazardous Voltage Limitations (68.306) of Part 68 FCC Part 68 testing Applicable tests from the list below will be re-performed on random samplings of the CSL-8308 at not greater than semi-annual intervals, by Mr. J. P. Neil, P.E., Mountain View, California, as indicated by his engineering judgement. 68.302 Environment Simulation 68.304 Leakage 68.306 Hazardous Voltage Limitations 68.308 Signal Power Limitations 68.310 Longitudinal Balance Limitations 68.312 On Hook Impedance Limitations 68.314 Billing Protection Sincerely, Lawrence C.
