In a communication system, a first communication unitof an equipment servercommunicates messages in a common data format with plural device servers. A equipment control unitcontrols the access control systemincluding one or more passage restriction units, based on the message received by the first communication unit. The passage restriction unitsare provided in the buildingso as to be capable of restricting passage of plural devices. The device servertransmits the message to the equipment serverwhen the devicepasses through a place where the passage restriction unitis provided. The equipment control unitdetermines whether or not the message is invalid based on the message received by the first communication unit. The equipment control unitoutputs an authentication request to the access control system

Equipment server, device server, and communication system

A cable connector holder including a base configured to hold a plurality of cable connectors and a press part attached to the base and extending above the plurality of cable connectors, wherein the lever is configured to uniformly press down on each of the plurality of cable connectors to render the cable connectors collectively removable from a network device. The cable connector may further include a press prevention mechanism that prevents the press part from engaging the levers of the cable connectors, thereby preventing the removal of the plurality of connectors in the connector holder from a network device.

Secure connection device

There is disclosed a method of inspecting an optical waveguide substrate for optical conduction at an increased inspecting rate and also inspecting an optical waveguide substrate for cross-talk. According to the disclosed method, a laser beam is applied from a laser beam scanning optical system to one end face of an optical waveguide of an optical waveguide substrate which is an object to be inspected, and the laser beam emitted from the other end of the optical waveguide is detected by a CCD camera, which output detected result data. A light spot position confirming device compares the detected result data with stored data.
