The Scientific Atlanta® 6940 was manufactured originally as a 3 or 4 output node, sometimes with RF Backup. This model was never intended for segmentation, and was only produced in a Single Forward and Single Return configuration. While there are multiple Receiver and Transmitter locations, these are configured for Redundancy and Split Band operation, and not Segmentation. CableServ® has developed Forward and Return field installable Segmentation solutions for these Nodes.
