Patent ID: 8442228

Claim:
A multi-class switching system, comprising: a coder/decoder for converting voice between analog and digital; a first switch coupled to the coder/decoder to isolate non-secure entities in a dial-up network and comprising fiber optic ports to pass classified and unclassified data to one of a classified IP network and an unclassified IP network; an encryption device coupled to the first switch to encrypt digitized voice; a second switch coupled to the encryption device and directly to the first switch, wherein the second switch receives encrypted digital voice from the encryption device connection and unencrypted digital voice from the direct connection, and wherein the first switch and the second switch operate in a plurality of states including secure, non-secure, and cut-off; a fiber optic (F/O) switch coupled to the coder/decoder; and at least one controller that includes a state control module, power-on/off logic, network cut-off logic, remote control logic to control states of the first switch, the second switch, and the F/O switch, and that stores and retrieves sensitive coder/decoder parameters for operation of the coder/decoder and accesses the coder/decoder only when the first switch and the second switch both are in the cut-off state.
