Abstract

A method and apparatus for controlling two way communication via disparate physical media. A computer comprises a central processor, a forward channel interface, a return channel interface, and a main memory, each being coupled to a bus. The forward channel interface is further coupled to interrupt the central processor and coupled to receive a packet from a forward channel. The main memory contains an interrupt service routine comprising a first set of code for passing the packet to a routine for decapsulating the packet and a second set of code for passing a second packet to the return channel interface. The method comprises a computer transferring a packet from a forward channel interface to a main memory. The central processor analyzes the packet to determine if the packet is a data packet or a network management packet. If the packet is a network management packet, the central processor creates a response packet and passes the response packet to a return channel interface.
