Multiplex switching scheme for communications network
First Claim
1. A method of processing packetized data, the method comprising:
- (a) receiving from a satellite at a switch a packet having a destination address and control bytes for elementary error detection;
(b) comparing at least a portion of the destination address with at least one addresses assigned to at least one terminal device connected to the switch; and
(c) routing the packet from the switch to a terminal device when the destination address corresponds to an address assigned to a terminal device connected to the switch.

Abstract
An earth station interface architecture provides full mesh connectivity for a relatively small number of network stations. A component of the architecture is a switch, which employs'"'"' a network interface standard to '"'"'define the multiplexing of multiple virtual ports across single physical communications port. Through address and control fields of its connectivity control software, the switch can be dynamically configured to provide multilayer addressing, and device selectivity, thereby enabling point-to-point connectivity of multiple terminal devices, such as a plurality of audio circuits, to be effected via a single port. Dial codes on the station side of an audio signal multiplexer link are translated into frame relay addresses (data link connection identifiers) that are added to each frame of data for routing through the network. With this additional layer of routing information, audio (voice) connectivity is now available between any two audio circuits (e.g. trunks) in the network.
