MMI system - contents


Definitions

MMI = Man Machine Interface

System consisting of software and peripherals. It i s used by the operator to perform operation and maintenanc e functions in the exchange system.

MML = Man Machine Language

A command language with which the operator can manage the operation of the exchange.

I/O syntax follows CCITT recommendations.

DIALOG / MML SESSIONSessions are either local sessions or remote sessions .

Communication between the system and the user using MML command language.

MMI system


General

Organised in a three level command hierarchy.

ON-LINE help.

Own MML program for every MML command group.

The MMI system loads the MML programs from a disk into the RAM when entered to the command group level.

To Restrict Access to certain commands

To prevent Unauthorized Access

Why Do We Need the Authority System ?Why Do We Need the Authority System ?


There are two rules

1) Command Authority (1 - 250)

Authority level for every command

2) Terminal Authority (1 - 250) / Superuser (251)

Authority level of the VDU

3) User Authority (1 - 250) / Superuser (251)

Authority level is given by command class to the user (rights)

There are three different groups of authority

1) The User Authority AND the Terminal Authority must be equal or greater thanthe Command Authority.

2) The User Authority OR the Terminal Authority must have the SuperuserAuthority (at least one for security reasons).

Authority System Groups
