Latest Patents
Ruffing's latest patents include a Delay Correction Circuit and a Carrier Terminal Unit. The Delay Correction Circuit is designed for use with an elastic store in a PCM time division multiplexed system. It monitors the relative positions of the read and write addresses supplied to the elastic store. In cases where the read or write addresses are overtaking each other within a predetermined range, the circuit initializes one of the address sources at a specific time to maintain a new relative position.
The Carrier Terminal Unit interfaces 1.544 MHz PCM lines to a digital switch, where voice samples are switched at 2.048 MHz. This unit provides essential functions such as bit synchronization, in-frame monitoring, delay equalization and correction, framing detection, and rate and format conversion. A common memory is utilized for these functions, acting as an elastic store for delay equalization. The unit also includes mechanisms for monitoring the relative positions of memory read and write addresses, ensuring efficient data handling.
