专利汇可以提供Connection system of portable type input/output device专利检索,专利查询,专利分析的服务。并且PURPOSE:To economically execute a test from a portable type input/output device, by setting a channel between a subscriber's terminal of a remote line collecting means to which the portable type input/output device is connected, and a trunk provided with a means to be connected to a CPU. CONSTITUTION:A maintenance person who has proceeded to a remote station RO connects a portable type input/output device PIO to a network NW3 of a remote line collecting means RLC. A central station CO inputs a command for setting a channel between the subscriber's terminal to which the PIO has been connected, and a trunk TRK provided with a lead-in adaptor ADP which can be connected to a CPU. The CPU which has received this command sets a path 1 and a path 2 to a network NW1 of a distributing means SM and the NW3, respectively, and also forms a channel connecting the TRK and the PIO by utilizing an idle time slot on a PCM link. Also, the TRK is connected to the CPU by operating a switch SW provided in the ADP. After that, a command inputted from the PIO is transferred to the CPU, and a desired test is executed.,下面是Connection system of portable type input/output device专利的具体信息内容。
