Abstract:
PURPOSE: To enable high speed communication between terminal equipments and simultaneous plural terminal communication, etc., by connecting a computer to a primary group interface not through a gateway machine so as to avoid a delay in a connection time and a data transfer time via the gateway machine.
CONSTITUTION: A primary group interface board 4 is built in the computer 1. The primary group interface board 4 is of a MAIN board 4a with a communication controller mounted thereto and a COM board 4b with 11 sets of communication controllers mounted thereto separately. Thus, when the H1 service provided at present is in use, only the MAIN board 4a is built in the computer 1 and when a 23B+D service is in use, the COM board 4b is connected to the MAIN board 4a.
