Abstract
A method of providing a back up communications link for control messages within a delivery unit. The primary means of transport for both network data and control data within the delivery unit is by means of ingress and egress buses between application modules of the delivery unit. However, control messages from a unit controller can also be delivered by means of a separate link, typically to a bus control module.
