Abstract: A DC-coupled data slicer operates on a baseband signal based on a variable threshold and an AC-coupled data slicer operates on the baseband signal based on a fixed threshold. The variable threshold is initially set to a stored threshold value corresponding to a previously used value of the variable threshold. Differences between DC-coupled sliced data and the AC-coupled sliced data are determined and used to adjust the variable threshold. In one embodiment, the AC-coupled data slicer is characterized by a settling time constant. The variable threshold is not adjusted until expiration of a predetermined delay preferably set to be a multiple of the settling time constant. After expiry of the predetermined delay, adjustments to the variable threshold are made to correct any detected variances in the expected duty cycle of the DC-coupled data slicer output. In this manner, the present invention overcomes the problems resulting from settling times inherent in prior art techniques.

Abstract: A system for routing data and communications to one of a plurality of remote sites to promote reciprocal interaction among the remote sites. The system includes a central processing unit and a storage device to store a first set of data identifying a plurality of remote sites and a second set of data identifying the frequency at which each of the remote sites communicates with the system. The system selects a particular remote site to receive a particular communication by analyzing the second set of data. The system also contemplates a method of routing data and communications including the steps of storing routing data for identifying a plurality of remote sites and the frequency at which each of the remote sites communicates with a central processor, receiving a communication at the central processor, analyzing the routing data to select a particular remote site, and forwarding the communication to the selected remote site.
