Abstract
Abstract A network apparatus having a chassis with an external network data port and a removable electronic module coupled to the network data port through an internal data port when the removable electronic module is present in the chassis. The chassis may also provide power, radio frequency (RF), data bus, and other types of electrical and data connections to the electronic module through the use of additional internal ports. The apparatus may additionally be connected to others via a data bus, and be included as part of a rack-mounted system. The electronic module may be inserted and removed from the chassis while electrical power is applied to the chassis.

Claim 2
Dependent Claim
126 words
A network apparatus comprising: a chassis having an external network data port at each of a plurality of positions; an internal network data port coupled to the external network data port; a plurality of external radio frequency (RF) connectors coupled to the chassis at each of the plurality of positions; a plurality of internal RF connectors, each of the plurality of internal RF connectors coupled to one of the plurality of external RF connectors; and a removable electronic module having a module network data port electronically coupled to the internal network data port and a plurality of module RF connectors electrically coupled to the plurality of internal RF connectors when the removable electronic module is present in the chassis at one of the plurality of positions.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1 wherein the electronic module comprises a distal edge and a proximal edge, the module data port and the plurality of module RF connectors are located substantially along the proximal edge.
Claim 4
Dependent Claim
76 words
The apparatus of claim 2 further comprising: one or more power supply modules coupled to the chassis; a plurality of internal power connectors coupled to the one or more power supply modules; and a module power connector coupled to the electronic module, wherein the module power connector is electrically coupled to one of the plurality of internal power connectors when the removable electronic module is present in the chassis at one of the plurality of positions.
Claim 5
Dependent Claim
21 words
The apparatus of claim 3 wherein the module power connector is located substantially along the proximal edge of the electronic module.
Claim 6
Dependent Claim
67 words
The apparatus of claim 2 further comprising: an internal data bus connector coupled to the chassis; and a module data bus connector coupled to the electronic module, wherein the module data bus connector is electrically coupled to the internal data bus connector when the removable electronic module is present in the chassis, the module data bus connector located substantially along the proximal edge of the electronic module.
Claim 7
Dependent Claim
24 words
The apparatus of claim 2 further comprising an electronic display coupled to the electronic module substantially along the distal edge of the electronic module.
Claim 8
Dependent Claim
25 words
The apparatus of claim 1 wherein the electronic module may be inserted and removed from the chassis while electrical power is applied to the chassis.
Claim 9
Independent Claim
166 words
A method for scaling a head end in a data-over-cable service network, the method comprising: connecting a plurality of head-end coaxial cables to a plurality of external radio frequency (RF) connectors at one of a plurality of positions on a chassis, each of the plurality of external RF connectors being coupled to one of a plurality of internal RF ports; connecting an external network connection to an external network data port at the one of the plurality of positions on the chassis, the external network data port being coupled to an internal network port; and inserting an electronic module at the one of the plurality of positions on the chassis, the electronic module having a plurality of module RF ports and a module network port, the insertion coupling the plurality of module RF ports to the plurality of internal RF ports and coupling the module network port to the internal network port, thereby incrementally increasing the scale of the data-over-cable service network provided by the head-end.
Claim 10
Independent Claim
166 words
A method for scaling a head end in a data-over-cable service network, the method comprising: connecting a plurality of head-end coaxial cables to a plurality of external radio frequency (RF) connectors at one of a plurality of positions on a chassis, each of the plurality of external RF connectors being coupled to one of a plurality of internal RF ports; connecting an external network connection to an external network data port at the one of the plurality of positions on the chassis, the external network data port being coupled to an internal network port; and inserting an electronic module at the one of the plurality of positions on the chassis, the electronic module having a plurality of module RF ports and a module network port, the insertion coupling the plurality of module RF ports to the plurality of internal RF ports and coupling the module network port to the internal network port, thereby incrementally increasing the scale of the data-over-cable service network provided by the head-end.
Claim 11
Dependent Claim
63 words
The method of claim 8, further comprising: removing the electronic module from the one of the plurality of positions on the chassis, the removal uncoupling the plurality of module RF ports from the plurality of internal RF ports and uncoupling the module network port from the internal network port, thereby incrementally decreasing the scale of the data-over-cable service network provided by the head-end.
Claim 12
Dependent Claim
97 words
The method of claim 8, further comprising: removing the electronic module from the one of the plurality of positions on the chassis; and inserting a second module at the one of the plurality of positions on the chassis, the second module having a second plurality of module RF ports and a second module network port, the insertion coupling the second plurality of module RF ports to the plurality of internal RF ports and coupling the second module network port to the internal network port, thereby maintaining the scale of the data-over-cable service network provided by the head-end.
