1.1.1

Interactive processing mode

NACCS can operate in the following interactive processing modes: interactive processing mode (forpackaged software), interactive processing mode (SMTP two-way), WebNACCS processing mode (forWeb browser), and interactive processing mode (ebMS).

1.1.1.1

Interactive processing mode (for packaged software)(1) Interactive processing mode (for packaged software)This mode allows the user computer to connect to the NACCS Center server by TCP/IP as
network and transport layers and by HTTP as its upper layer.
Data are transmitted and received one by one.
This type of processing is hereinafter referred to as interactive processing mode (interactive).
(2) Interactive processing mode (for "Packaged Software – Processing Mode Using netNACCS")
This mode allows the user computer to connect to the NACCS Center server by TCP/IP as
network and transport layers and by HTTPS as its upper layer. This is a version of interactive
processing mode used on the Internet.
Data are transmitted and received one by one.
This type of interactive processing is hereinafter referred to as interactive processing mode(netNACCS).

1.1.1.2

Interactive processing mode: SMTP two-way (for gateway computers)

In this mode, an SMTP server is installed on both the user side and the NACCS Center server, andconnections are established by TCP/IP as network and transport layers and by SMTP as its upperlayer.
Data are transmitted and received one by one.
This type of processing is hereinafter referred to as interactive processing mode (SMTP two-way).

! 'Packaged Software - Processing Mode Using XXX' refers to a type of packaged software
provided by NACCS Center. See "Operation Manual for NACCS Packaged Software" fordetails on types and functions of packaged software.

1.1.1.3

WebNACCS processing mode (for web browser)

This mode allows the user computer to connect to the NACCS Center server by TCP/IP as networkand transport layers and by HTTPS as its upper layer. NACCS center web server is accessed from aweb browser on the user computer and operations are carried out by the input on the operation
screen displayed or by actions such as pressing the buttons. Then the processing result screen will
be displayed.
This processing mode is hereinafter referred to as WebNACCS processing mode (web browser).

1.1.1.4

Interactive processing mode: ebMS processing mode (for gatewaycomputers)

This mode allows the ebMS server and the NACCS Center server to connect to the network andtransport layers by TCP/IP and to its upper layer by HTTPS, and data processing is carried out using
ebMS2.0. By using a multi payload function, multiple blocks of request can be transmitted in a batch.
This type of interactive processing is hereinafter referred to as interactive processing mode (ebMSprocessing mode).

1.1.2

E-mail style processing mode

For the e-mail style processing mode in NACCS system, only e-mail style processing mode (forgateway computers) is available.

1.1.2.1

E-mail style processing mode for gateway computers

In this mode, the user's gateway computer and the NACCS center server are connected by TCP/IP
as network and transport layers and by SMTP/POP3 as its upper layer.
Multiple requests can be transmitted at the same time. Processing results need to be retrieved (orreceived) from the NACCS Center server in a batch after a certain period of time.
