Title:
METHOD AND DEVICE FOR ADJUSTING OSCILLATOR
Document Type and Number:
Japanese Patent JP2001308833
Kind Code:
A
Abstract:
To realize a method for adjusting an oscillator via a packet exchange network.
The packet exchange network 21 is located between the oscillator 44 and a specified time source 31, and the time source 31 knows the clock time with specified accuracy. A clock 42, existing on the same side as that of the adjustable oscillator 44 of the network 21, is updated on the basis of the clock time known by the source 31 via the network 21. The clock 42 is used to adjust the oscillator 44 in order to make the oscillator 44 oscillate at a desired frequency.
