A multi-service access platform may have network interface cards and application cards. The network interface cards may interface the multi-service access platform to an ingress network and an egress network. The network interface cards may be coupled to the application cards by a network distribution bus. As a result, the application cards may perform digital signal processing on signals received from the ingress network. Additionally, the application cards may be coupled to a packet switching fabric. The packet switching fabric may facilitate exchange of signals between the application cards. Additionally, the packet switching fabric may permit exchange of the signals with the egress network.
