SBC requires all equipment to meet the requirements of their TP76200MP document dated July 1998. In Section 8, there is a grouping of tests taken from ANSI T1.315-1994 that requires proper operation of equipment from -42VDC to -56.5 VDC over the expected life of the equipment. There is a short term requirement for proper operation at -40VDC for one minute and at -75VDC for 10mS. There is a battery drop out test in which the equipment must recover and not be damaged when the input battery voltage is 0VDC for 5mS. There is also a requirement to determine at what battery voltage the equipment will be damaged (if it can be damaged).
SBC requires this information in the form of a test report. Hope this helps, Jim Jim Wiese Compliance Engineer ADTRAN, INC. 901 Explorer Blvd. P.O.
