Apparatuses, systems and methods that operate to print information and documents stored on a mobile terminal device. In a state where a call path between an outside line and a call center is formed, the outside line is connected to an outside line transfer destination when a transfer demand from the call center to the outside transfer destination is received and the outside line is automatically reconnected to the call center when the call between the outside line and the outside line transfer destination ends. The ring and the fins may be integrally formed in one piece. The second magnetic device is disposed on the slide cover. The scheduling may include controlling a terminal to facilitate interfacing an Internet Protocol network with a point-to-multipoint network where the P2MP network includes one or more aggregating devices to facilitate interfacing signaling with devicesunits associated with one or more subordinate P2MP networks. When rings are connected through a shared link formed between two shared bridges, rings with higher priorities carry control packets of rings with lower priorities so that, in case of failure of the shared link, a single ring may be formed from the connected rings with only the master bridge of the higher priority ring aware of and monitoring the larger ring.
