摘要： PURPOSE:To conduct the line test of all signal systems and protocols in common by transmitting a call setting message including subscriber identification or inter-station line identification information from a test terminal connected to a subscriber's line. CONSTITUTION:The call control signal from common signal lines 8 and a common line controller 4 which process the signal of an inter-station line and the call control signal from a subscriber's line controller 3 which processes the signal of subscriber's lines 6 are transferred to a call controller 2 and are processed there. A test terminal 7 is connected to one subscriber's line 6. Since subscriber identification or line identification information is included in the call setting message from the test terminal 7, the call controller 2 does not regard this call as the call from the test terminal 8 but regards it as the call and incoming of designated subscriber identification or line identification to execute the call control. Thus, the line test of all signal systems and protocols is conducted in common.

摘要： PURPOSE:To execute flow quantity control with information in a layer 3 level by blocking a link when the counter value of a flow quantity counter goes over a put class. CONSTITUTION:When an I-frame to be sent from a transmitting source 1 is inputted from an input terminal 11 to a frame exchange part 10, the frame exchange part 1-counts up a flow quantity counter 20. The value of the flow quantity counter 20 is read per constant time by a comparing part and compared with the value of the through-put class, which is written from a through-put class input part to a through-put class storing part 30 in advance. When the flow quantity goes over the through-put class, a link blocking control part 50 is activated and the link is blocked by the self-station busy setting command of a CCITT recommending I. 441 and hereafter, an RNR frame is returned even when a packet is received. Thus, traffic is counted by a layer 3 and the flow quantity can be controlled according to the information.

摘要： PURPOSE:To absorb function alteration in a subdivided function block and to attain the loose coupling and virtuality and the dispersion of software through the use of a uniform No.7 common line signal system by defining a logical processor at every subdivided function on a physical processor and defining the function block at every furthermore subdivided function in a logical processor unit. CONSTITUTION:A function unit which does not bring a considerable power drop even if it is separated from other functions and which is physically accommodated in the other processor is set to the setting reference of the logical processor. A resource control logical processor and a maintenance/operation control logical processor controlling a maintenance operation are provided. A call control part and a protocol control part are separated and a uniform call control common primitive is defined between the call control part and the protocol control part, and between the call control part and a CCUP part. Thus, the common call control part which does not depend on the protocol is supplied, and the call control part is separated into a basic call control part and an additional service part. Consequently, software having flexibility which can follow an ISDN developing over a network provided with various intelligence can be developed.
