Abstract
A hub port in a hub of a loop network which detects and replaces invalid data and invalid control signals in the datastream of the loop. The hub port detects invalid data and invalid control signals or primitives received from an attached node port and substitutes buffer data or valid primitives. The hub port substitutes buffer data or primitives which have correct running disparity for the datastream at the point of substitution. In another implementation, an error detection device is included in a loop network and monitors the datastream of the loop network. The error detection device detects invalid data and invalid control signals or primitives received from an upstream node in the loop and substitutes buffer data or valid primitives. The error detection device substitutes buffer data or primitives which have correct running disparity for the datastream at the point of substitution.
