DS3 Path Conditioning
E3 Path Conditioning
DS3 path conditioning is shown in
CSP through integration of event conditions. A software configurable auto-insertion
function is provided for downstream path conditioning.
Instead of the typical DS3 AIS pattern of an alternating pattern of 1s and 0s, the
CX29503 implements the DS3 AIS pattern as unchannelized all 1s to force the
CX28500 device to abort the message transaction.
E3 path conditioning is shown in
function is provided for downstream path conditioning.
