The first plurality of computer devices has core nurse call functionality. The system also includes a second plurality of computer devices communicatively coupled to the first plurality of computer devices. The first plurality of computer devices are interconnected logically and/or physically in a tiered architecture arrangement to provide fault isolation among the tiers so that faults occurring in computer devices of one tier don't affect the operability of computer devices in other tiers and so that faults occurring in any of the second plurality of computer devices don't affect the core nurse call functionality of the first plurality of computer devices. ## Claims ### Claim 1 A healthcare communication system comprising: a first plurality of computer devices operable as a nurse call system, the first plurality of computer devices having core nurse call functionality residing on an embedded computing platform, at least one of the first plurality of computer devices having a graphical display screen, and a second plurality of computer devices operable to provide the first plurality of computer devices with additional functionality via at least one software plug-in that is transmitted from at least one of the second plurality of computer devices to at least one of the first plurality of computer devices. ### Claim 2 (depends on 1) The healthcare communication system of claim 1, wherein the graphical display screen has a user interface that, when used by a user, results in the at least one software plug-in being transmitted to at least one of the first plurality of computer devices. ### Claim 3 (depends on 2) The healthcare communication system of claim 2, wherein the at least one of the first plurality of computer devices to which the at least one software plug-in is transmitted comprises at least one of a master station, a patient room station located in a patient room of the healthcare facility, an input/output (I/O) circuit that is coupled to the patient station, or a staff station located in a staff work area of the healthcare facility. ### Claim 4 (depends on 1) The healthcare communication system of claim 1, wherein the at least one software plug-in is operable to change the user interface of the graphical display screen to a different user interface. ### Claim 5 (depends on 1) The healthcare communication system of claim 1, wherein the second plurality of software devices are configured such that the at least one software plug-in is transmitted to the at least one of the first plurality of computer devices on an as needed basis as dictated by use of the at least one of the first plurality of computer devices. ### Claim 6 (depends on 1) The healthcare communication system of claim 1, wherein the second plurality of software devices are configured such that the at least one software plug-in is transmitted to some or all of the first plurality of computer devices in response to use of at least one of the second plurality of computer devices. ### Claim 7 (depends on 1) The healthcare communications system of claim 1, wherein software upgrades or updates installed on at least one of the second plurality of computer devices are distributed automatically to at least some of the first plurality of computer devices. ### Claim 8 (depends on 7) The healthcare communications system of claim 7, wherein the software upgrades or updates are also distributed automatically to at least one other computer device of the second plurality of computer devices. ### Claim 9 (depends on 1) The healthcare communications system of claim 1, wherein, in response to a new computer device being added to the first plurality of computer devices, at least one of the second plurality of computer devices automatically transmits at least one software plug-in to the new computer device. ### Claim 10 (depends on 1) The healthcare communications system of claim 1, wherein the core nurse call functionality comprises functionality regulated by a regulations entity and the additional functionality comprises non-regulated functionality. ### Claim 11 (depends on 1) The healthcare communications system of claim 1, wherein at least one of the first plurality of computer devices and the second plurality of computer devices incorporates Publish and Subscribe (PubSub) data communication technology. ### Claim 12 (depends on 1) The healthcare communication system of claim 1, wherein at least one of the first plurality of computer devices is communicatively coupled to a hospital bed and receives bed status data from the hospital bed. ### Claim 13 (depends on 1) The healthcare communication system of claim 1, wherein at least one computer device of the first plurality of computer devices has auto-discovery software that is operable, in response to installation of the at least on computer device in the nurse call system, to detect network connectivity and to initiate communications with a device manager. ### Claim 14 (depends on 13) The healthcare communication system of claim 13, wherein the device manager is operable to provide software modules and/or network settings to the at least one computer device of the first plurality of computer devices. ### Claim 15 (depends on 1) The healthcare communication system of claim 1, further comprising least one additional computer device that is coupled to at least one of the computer devices of the first plurality or second plurality of computer devices and that incorporates Session Initiation Protocol (SIP) voice over Internet protocol (VoIP) technology to separate the setting up and tearing down of voice calls between SIP enabled voice endpoint devices. ### Claim 16 (depends on 15) The healthcare communication system of claim 15, wherein the at least one additional computer device comprises a VoIP private branch exchange (PBX). ### Claim 17 (depends on 1) The healthcare communication system of claim 1, wherein at least one of the first computer devices comprises a VoIP room gateway that is operable to distribute communication data to multiple voice terminals or VoIP voice endpoints installed in patient rooms and hallways. ### Claim 18 (depends on 1) The healthcare communication system of claim 1, wherein the first plurality of computer devices are interconnected in a tiered architecture arrangement to provide fault isolation among the tiers so that faults occurring in computer devices of one tier don't affect the operability of computer devices in other tiers. ### Claim 19 (depends on 18) The healthcare communication system of claim 18, wherein at least one of the tiers comprises a subset of the first plurality of computer devices that is associated with a patient room. ### Claim 20 (depends on 18) The healthcare communication system of claim 18, wherein at least one of the tiers comprises a subset of the first plurality of computer devices that is associated with a nursing unit having a plurality of patient rooms.
