2. SIMULTANEOUS INTERPRETATION FOR A REMOTE INTERFACE

2.1 Introduction

The Simultaneous Interpretation Remote Interface is part of the DCN Next Generation

software that allows for another controlling entity outside the CCU, not being the DCN Next

Generation Control PC, to use the Simultaneous Interpretation application.

2.2 Remote Simultaneous Interpretation Control

Simultaneous Interpretation is the application that allows preparation and monitoring over the

functionality of the interpreter desks. Typical control issues are e.g.: setting a desk

configuration, changing the interlock mode, changing the channel languages etc. More details

on the complete IN application can be found in the user manual.

Controlling Simultaneous Interpretation with a remote interface is achieved by means of

calling a defined set of Remote Functions and acting upon a defined set of Update

Notifications. The general concept of Remote Functions and Update Notifications is described

in [SRS_INF]. [SRS_INF] also describes the protocol and hardware conditions concerning the

remote interface.

Together with this remote interface, there are at the moment two locations in a fully

connected CCU where IN can be influenced. These locations are:

• A remote controller (which can be the control PC) connected using an Ethernet (in case of

MCCU) or RS-232 (in case of SCCU) connection. This remote controller uses Remote

Function calls to control Simultaneous Interpretation.

• The actual interpreter units that handle their interpreter desk control keys.

To get a fully operational system the remote controller must register itself to the CCU, in order

for it to receive update messages from the CCU.

Remote functions coming from the remote controller can initiate an update in the CCU.

During the update, notifications are generated and sent to the remote controller.

During the processing of remote functions on the CCU, the update messages are created and

transmitted. This implies that the response information of a remote function can be received

after the reception of an update notification. The remote controller must wait for the response

of the remote function. After reception of the response appropriate action should be taken

upon the error code returned. The notifications received during the wait for the response may

be processed directly. See [SRS_INF] for details on this mechanism.

Events coming from a unit (interpreter desk) are processed and the CCU is updated.

Although there are no events that directly lead to generating and sending notifications, there

are unit events that indirectly lead to notifications. These notifications are sent to the

registered remote controller.

This document gives the set of Remote Functions and the set of Update Notifications

concerning Simultaneous Interpretation. The relation between Remote Function, sent by the

remote controller, and Update Notifications is given in the description of each separate

Remote Function. The (indirect) relation between unit events and Update Notifications is

given in section 4.1.2.
