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.
