Title:
SEMICONDUCTOR DEVICE FOR COMMUNICATION CONTROL
Document Type and Number:
Japanese Patent JPH06335078
Kind Code:
A
Abstract:

PURPOSE: To reduce the cost by actuating the semiconductor device for a terminal equipment like a simulated NT so as to make simple counter communication between TE and NT thereby suppressing increase in the chip area.

CONSTITUTION: A receiver 1 received data D11 via a signal line 10 and converts the data into data DI2 and a frame correction section 2 corrects the data DI2 into data DI3 of a format of a terminal equipment. A selector 3 receives th data DI2, DI3 to provide one of them to a terminal equipment reception section 4. A frame correction section 6 corrects the data D01 multiplexed by the terminal equipment transmission section 5 into data D02 of a format of a network terminator. The transmission circuit 8 receives the data D01 or D02 outputted from a selector 7 and converts the data into the data D03 and they are sent via a signal line 11. A control section 9 controls the terminal equipment transmission section 5 to output data DO1 at the test and controls the selectors 3, 7 to select the data DI3, D02.
