Procedure for Setting Office Data for OAI Services

3.4 TCP/IP Address (Assignment from MAT)

3.4.1Functional Outline

In an OAI system to be connected with the host computer via the Ethernet, this function allows use of TCP/IP port with the self internet address (TCP/IP address) of the NEAX2400 IMX assigned from the MAT.

Also, whether system message “4-R” (IOC card for the host computer is faulty) is to be output or not when the connection with the host computer has been normally disconnected can be selected by switch setting on the Interface Processor (IP).

3.4.2Using Conditions

1.Due to the hardware limitation, only one physical TCP/IP port can be accommodated per system.

2.Basic Value of TCP/IP Address is “172.16.253.0”.

3.The TCP/IP addresses (A, B, C, D) that cannot be used by this function are as follows.

Classes A, B, and C can be used. Note that Host Number = 0 cannot be used. (Conditions [1] ~[3]. Classes D and E cannot be used. (Condition [4])

Class A:

[1]

0 < A < 127

A, 0, 0, 0

 

 

 

Class B:

[2]

128

< A < 191

A, B, 0, 0

(0 < B < 255)

 

Class C:

[3]

192

< A < 223

A, B, C, 0

(0 < B < 255,

0

< C < 255)

Class D, E: [4]

244

< A

A, B, C, D

(0 < B < 255,

0

< C < 255, 0 < D < 255)

4.System message “4-R” output can be stopped by switch setting on the System Data only when TCP connection has been disconnected (Normal) (ERRK=01).
