Trying to decode an e-mail from a former associate of mine.
---< START OF MESSAGE >---
"What is a CCITT requirement? What other requirements are to be met
for agency approval based on the information provided below?:
The Power Supply is required to either a 110 VAC or a 220 VAC
input.
The Ac input supply should be a power factor corrected (PFC) design with
a continuous operating range of 90 to 265 VAC at 47 to 63 Hz."

1. As far as I knew, CCITT (Consultative Committee on Interantional
Telegraphy and Telephony, part of the ITU) imposed nothing.
They are a standards body the can only recommend. Their standards
are translated by different countries into national standards.
2. This sounds like a 555 power spec for power supplies
not for ITE, i.e. not for 950. That is to say, he must
make sure that his power supply vendor gets this approval.
Someone out there correct or educate?
