Abstract
The present invention provides a line accommodation device comprising at least one first communication control unit for controlling information transmission/reception to/from a first communication system, at least one second communication control unit for controlling information transmission/reception to/from a second communication system using the first communication system as a communication medium and a route control unit for controlling the switching of an information transfer route between the first and second communication unit.
Claims15
A line accommodation device, comprising:
- at least one first communication control unit for controlling information transmission and reception to and from a first communication system;
- at least one second communication control unit for controlling the transmission or reception of information to or from a second communication system using the first communication system as a communication medium;
- and
- route control unit for controlling the switching of an information transfer route between the first communication control unit and the second communication control unit.
A control method of a line accommodation device which comprises a first communication control unit for controlling information transmission and reception to and from a first communication system and a second communication control unit for controlling information transmission and reception to and from a second communication system using the first communication system as a communication medium, comprising:
- a first step of building the second communication system by connecting the first communication control unit and the second communication control unit via a route control unit for controlling switching of an information transfer route between the relevant first communication control unit and the second communication control unit;
- and
- a second step of modifying the information transfer route when extending or removing the first and/or second communication control unit.
A signal for carrying a control program of a configuration control unit of a line accommodation device which comprises a first communication control unit for controlling information transmission and reception to and from a first communication system, a second communication control unit for controlling information transmission and reception to and from a second communication system using the first communication system as a communication medium and a route control unit for controlling switching of an information transfer route between the first and second communication control unit, for enabling the configuration control unit to realize:
- a function of enabling the route control unit to set the information transfer route for bypassing failed second communication control unit when the second communication control unit fails or disconnecting failed second communication control unit from the line accommodation device;
- and
- a function of determining the adding position of the second communication control unit in the relevant second communication system when adding the second communication control unit to an arbitrary second communication system.
