Introduction

This note gives an outline of enhancements to the Integrated Electronic Control Centre (IECC) Timetable Processor (TTP) implemented as part of the latest software release, known as Upgrade 001. These TTP enhancements are also known as TTP95.

The aim of the enhancements is twofold. Firstly to improve the quality of timetable data provided to ARS and hence improve ARS operation. Secondly to make the TTP system easier to maintain and to reduce the need for TTP support.

The enhancement consists of six packages:

Timetable validation and rule counting

Technician facilities

UNIX/BRX interface improvements

Amendment timetables

Timetable access methods

Modifications to ACI at midday and midnight

It should be noted that the six packages are not independent and must be installed at the same time.

Only the changes that pertain to the TTP data preparers are contained herein.
