Abstract
Abstract A system for the exchange of digital information packets includes an exchange with connectors to allow modular expandable units to connect to the exchange over transmission media. The modular expandable units send digital information packets from one to another over the exchange in response to requests for these digital information packets. The exchange allows for billing and other administrative functions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
262 words
A system for the exchange of digital information packets, comprising: an exchange including a plurality of connectors for interfacing said exchange to a plurality of transmission media; a plurality of modular expandable units, each of said plurality of modular expandable units having at least one input source terminal, at least one output terminal, and a central processing unit between said at least one input and said at least one output terminals; and at least two transmission media; wherein said plurality of modular expandable units are connected to said exchange through said at least two transmission media to allow a first transfer of a user-selected amount and type of digital information from a first one of said plurality of modular expandable units to a second one of said plurality of modular expandable units, wherein said user-selected amount and type of digital information is selected by inputting commands via an input device to software within each of said plurality of modular expandable units which locates and requests the transfer of the digital information packet, and wherein said plurality of modular expandable units are connected to said exchange through said at least two transmission media to allow a second transfer of a user-selected amount and type of digital information from the second one of said plurality of modular expandable units to at least a third one of said plurality of modular expandable units, such that said first one of said plurality of modular expandable units transfers data to said second one of said plurality of modular expandable units over at least two transmission media simultaneously.
Claim 2
Independent Claim
262 words
A system for the exchange of digital information packets, comprising: an exchange including a plurality of connectors for interfacing said exchange to a plurality of transmission media; a plurality of modular expandable units, each of said plurality of modular expandable units having at least one input source terminal, at least one output terminal, and a central processing unit between said at least one input and said at least one output terminals; and at least two transmission media; wherein said plurality of modular expandable units are connected to said exchange through said at least two transmission media to allow a first transfer of a user-selected amount and type of digital information from a first one of said plurality of modular expandable units to a second one of said plurality of modular expandable units, wherein said user-selected amount and type of digital information is selected by inputting commands via an input device to software within each of said plurality of modular expandable units which locates and requests the transfer of the digital information packet, and wherein said plurality of modular expandable units are connected to said exchange through said at least two transmission media to allow a second transfer of a user-selected amount and type of digital information from the second one of said plurality of modular expandable units to at least a third one of said plurality of modular expandable units, such that said first one of said plurality of modular expandable units transfers data to said second one of said plurality of modular expandable units over at least two transmission media simultaneously.
Claim 3
Dependent Claim
37 words
The system for the exchange of digital information packets of claim 1, wherein said output terminal include a module selected from a plurality of available expansion modules, each of which can accomodate one variety of signal output.
Claim 4
Dependent Claim
58 words
The system for the exchange of digital information packets of claim 1, wherein said central processing unit includes: software running on a microprocessor suitable for selecting digital information; a system for entering commands; an input; an output; and a serial line such that said serial line connects said at least one input to said at least one output.
Claim 5
Dependent Claim
50 words
The system for the exchange of digital information packets of claim 1, wherein said central processing unit includes: software suitable for selecting digital information; a system for entering commands; and a parallel line; such that said parallel line connects said at least one input to said at least one output.
Claim 6
Dependent Claim
53 words
The system for the exchange of digital information packets of claim 1, further comprising: an information buffer connected to said expandable module; such that said information buffer allows for the asynchronous communication of digital information between said exchange and one of said two modular expandable units over said at least two transmission media.
Claim 7
Dependent Claim
52 words
The system for the exchange of digital information packets of claim 1, further comprising: an information buffer connected to said exchange; such that said information buffer allows for the asynchronous communication of digital information between said exchange and one of said two modular expandable units over said at least two transmission media.
Claim 8
Dependent Claim
33 words
The system for the exchange of digital information packets of claim 1, further comprising an expansion module coupled to said input source terminal, said expansion module accommodating a particular variety of signal input.
Claim 9
Dependent Claim
22 words
The system for the exchange of digital information packets of claim 1, wherein said exchange may be communicably connected to another exchange.
Claim 10
Independent Claim
216 words
A system for the exchange of digital information packets, comprising: an exchange including a plurality of connectors for interfacing said exchange to a plurality of transmission media; a plurality of modular expandable units, each of said plurality of modular expandable units having at least one input source terminal, at least one output terminal, and a central processing unit between said at least one input and said at least one output terminals; and at least one transmission medium; wherein said plurality of modular expandable units are connected to said exchange through said transmission medium to allow the first transfer of a user-selected amount and type of digital information from a first one of said plurality of modular expandable units to a second one of said plurality of modular expandable units, and wherein said plurality of modular expandable units are connected to said exchange through said transmission medium to allow the second transfer of a user-selected amount and type of digital information from the second one of said plurality of modular expandable units to at least a third one of said plurality of modular expandable units, such that said first one of said plurality of modular expandable units transfers data to said second one of said plurality of modular expandable units over at least two transmission media simultaneously.
Claim 11
Independent Claim
216 words
A system for the exchange of digital information packets, comprising: an exchange including a plurality of connectors for interfacing said exchange to a plurality of transmission media; a plurality of modular expandable units, each of said plurality of modular expandable units having at least one input source terminal, at least one output terminal, and a central processing unit between said at least one input and said at least one output terminals; and at least one transmission medium; wherein said plurality of modular expandable units are connected to said exchange through said transmission medium to allow the first transfer of a user-selected amount and type of digital information from a first one of said plurality of modular expandable units to a second one of said plurality of modular expandable units, and wherein said plurality of modular expandable units are connected to said exchange through said transmission medium to allow the second transfer of a user-selected amount and type of digital information from the second one of said plurality of modular expandable units to at least a third one of said plurality of modular expandable units, such that said first one of said plurality of modular expandable units transfers data to said second one of said plurality of modular expandable units over at least two transmission media simultaneously.
