The invention relates to a corridor indicator lamp (). The corridor indicator lamp () comprises a base assembly () which includes a plurality of compartments () and a plurality of separator walls (). The compartments () are open towards a front side () of the corridor indicator lamp (). The separator walls () separate at least some of the plurality of compartments (). In order to improve visibility of the indicator lamp (), an extension unit () is provided according to the invention. The extension unit () is configured to be mounted to the base assembly () and has a plurality of extension walls (). An at least partly transparent cover () may be further provided, which is adapted to receive the extension unit ().

Corridor indicator lamp comprising extension unit

A system and method for providing backup communications over an Ethernet cable are disclosed. A backup communication system (BCS) is provided as part of a networked (TCP/IP) hospital communication system. The BCS is coupled to an Ethernet cable used for normal TCP/IP communications. When TCP/IP communications are interrupted, the BCS receives patient call signals from patient room terminals over a secondary communication mode of the Ethernet cable, and transmits those call signals to a nurses' station. The call signals are transmitted as voltage coded data such as voltage pulses or static levels. The voltage can include call information. 10V can represent a normal patient call, 15V can represent a patient emergency call, and 24V can represent a code call. Information can be relayed back to the room terminals using the same signaling technique. Thus, basic communications can be achieved when TCP/IP communications are unavailable. Other embodiments are disclosed and claimed.

System and method for backup communication over ethernet

A system and method for providing backup communications using Power over Ethernet (PoE) are disclosed. A backup communication system (BCS) is provided as part of a networked (TCP/IP) hospital communication system. The BCS is coupled to a power line used to provide power to a PoE switch. When TCP/IP communications are interrupted, the BCS receives patient call signals from patient room terminals over a secondary communication mode of the power line, and transmits those call signals to a nurses' station. The call signals can be generated by coupling a pulse-coded AC signal onto the PoE wires, or by sending voltage coded data in one direction and current-coded data in the other direction. Different signals or signal levels can be used to distinguish normal patient calls, patient emergency calls, and code calls. Thus, basic communications can be achieved when TCP/IP are unavailable. Other embodiments are disclosed and claimed.
