A bus control module for a delivery unit, which interfaces an optical fiber network to a switching matrix. The bus control module controls transport of control data and network data between various application modules of the delivery unit. The control data and network data are carried as datagrams on ingress links from the application modules and on egress links to the application modules.

[ What is claimed is:] [11.]11. A bus control module for a delivery unit, which interfaces high level network signals to a switching matrix and has a number of application modules that perform various network data transport functions, comprising:an ingress interface operable to receive ingress frames of data carried on ingress links from said application modules, wherein said ingress frames may contain control data subframes and network data subframes, each network data subframe having a payload to carry network data, each control data subframe having a payload to carry control data, said ingress interface operable to separate subframes containing network data from subframes containing control data;a multiplexer that receives subframes from said ingress interface and selects a subset of said subframes to be carried in an egress frame on said egress bus;an arbiter in communication with said ingress interface that controls assignments of said subframes to said egress frames;an egress slot memory in communication with said arbiter, said egress slot memory containing data used by said arbiter to determine positions in said egress frame for said subframes;an align and transmit unit that receives subframes from said multiplexer and that maps said subframes into said egress frames;a bus interface that receives subframes containing control data on said egress bus and that delivers subframes containing control data to said ingress interface; anda controller in communication with said bus interface that originates subframes containing control data for insertion on said egress bus and terminates subframes containing control data received on said ingress links.
