Semiconductor integrated switching apparatus |
摘要 |
A semiconductor integrated switching apparatus includes a space switch, a control memory, an output control circuit, an expanding circuit, an address comparator, and a maintenance reading circuit, all of which are integrated on a single substrate. The control memory controls switching operation of the space switch. The output control circuit transmits a highway signal selected by the space switch. The expanding circuit expands the capacity of the space switch. The address comparator reads out a written address signal upon writing thereof and compares a readout address signal with the written address signal. The maintenance reading circuit reads out an operation status signal of the space switch.
