2.1 OAI (Open Application Interface) System
1.The OAI system is the interface that joins a variety of facilities of the NEAX2400 IMX to th e app lica ti on
programs of the external computer (general-purpose information processing equipment) of the user.
2.The NEAX2400 IMX can be controlled by the external computer through the OAI system.
3.The OAI system diversifies the information processing functions of the NEAX2400 IMX, thus offering
users’ unique added values.
4.For implementing the OAI system, an Interface Processor (IP) is provided to the NEAX2400 IMX.
5.The IP controls the communication protocol between the NEAX2400 IMX and the UAP (User’s
Application Process or of the e xte rnal co mpute r) in accorda nce with the basic re fe rence model of th e Open
Systems Interconnecti on (OSI ) standar di zed by t he ISO (
Note
).
Note:
International Organization for Standar dization (ISO)
2.2 Software S tructure in the OAI System
The software structure in the OAI system is shown in Figure 2-1. So far, the software structure of the
NEAX2400 IMX is generally catego ri zed into three major blocks: Input Processing Block, Internal Processi ng
Block, and Output Processing Block. When the Input Processing Block detects a call, the Internal Processing
Block analyzes and identifies the call. In accordance with the result of this processing, the Output Processing
Block executes required switching operations, controlling of lamps/keys, etc. To meet these processing
requirements, a conventional arrangement is made every time a request for the application software arises. The
modules of the Input Pr ocessing Block and the Out put Processing Block ar e replaced with those corresponding
to such a reque st. However, in the case of the OAI syst em, each unit func tion to be made availa ble for the
computer in the Input Processi ng Block and the Output Proces sing Block is defined as a facility (each slant lined
portion in Figure 2-1) in advance, so that each of these facilities may be directly controlled by the external
computer through the OAI interface. For example, the key information input by processing of key receiving is
not processed withi n NEAX24 00 IM X, but is analyzed by the extern al computer. As a result of this processing
by the external computer, all the related messages are shown on a digital display and a lamp display at
corresponding termi nals. In other words, the OAI interface has relea sed the functio n of the conventional in ternal
processing to the external computers .

2.2.2Join of Facilities and Application
1. When a facility of the NEAX2400 IMX is c ontrol led by the Appl icat ion Prog ram ( AP) on th e UAP
computer, the AP and that facility must be connected first. The following is the procedure of this
connection.
(a) Set-up of Asso ciation
A communication path is to be opened so that the AP can communicate with the facility.
(b) Opening of Facility
The facility that the AP uses is to be declared to the NEAX2400 IMX, and then the AP and the
declared facility are joined.
2. Set-up of Association and Opening of Facility
Association is se t up by activation from the AP f irst , and th en th e ass ociat ion is rele ase d alon g with
the stop of the AP. W ithout t his associati on, the AP cannot communica te with the f acility and canno t
control the faci li ty, either.
Then, the facility must be ope ned s o as to allow the AP to comm unicat e wit h the fac ility throug h
the communication path opened by setting up of the associ ation. Opening of f acilit y is e xe cuted on
each facility basis.
As a result of the above procedure, the AP becomes able to freely control each of the facilities of
the NEAX2400 IMX, and a variety of applications can be programmed on the computer.

2.2.3Cope of Application in changeover of CPU System
Associations established between NEAX2400 IMX and External computer are released when
changeover of CPU system executes.
Therefore each applicat ion program cap must set up Asso ciation again afte r changeov er of CPU system.
