7.1 Clearing House (Level 4)

In the case of a single operator of all cards and tickets in use, the role of the Central Body can be undertaken by the operator, since all revenues are dedicated to that operator.

In case of multi operators, a Central Body operates a clearing house to allocate revenue to each operator.

7.2 Central Server (level 3):

It provides the functions to manage all equipments under its responsibility. It also manages stocks, revenue, fare collection and is responsible for forwarding all relevant information/data to the Central Body. Its role shall be:

Accounting, administrative and statistical functions: accounting of the receipts, statistics around sales and traffic levels, distribution of receipts, central management of transactions etc Functions of commercial management: management of the users and the cards,

Pricing functions: creation, modification, removal of identical pricing tables and identical configuration tables for equipment. The central system must provide practical and effective tools to staff in charge of pricing activities, so that they can easily use the pricing functions,

Security management, black list management and other information which allows for supervision of card usage and detection of fraud, controls flows, management of the secret keys etc

Technical management of the equipment: Centralisation of the alarms history which makes it possible to have a global vision of the behaviour of the equipment.

7.3 The Station Level controller SCU (Level 2):

The Station Level Controller provides equipment monitoring and a first level of equipment management.

Station operators where the ticket vending machines, ticket office machines and entry and exit access gates are installed need to have some local command to operate equipment depending on the local context:

Gate direction (entry / exit) configuration to adapt the station configuration in response to the passenger flow

Emergency gate opening

City ticket office or external retailer locations can also be considered as Level 2 locations.

7.4 Devices (Level 1):

Device level includes all AFC equipment such as TVM, Gate, POS, etc

7.5 Media – ticket, card (Level 0):

Card: Capability to use many types of card from multi source (mandatory)

7.6 Communications and Interfaces

Data communications for the AFC system, including information related to banking and finance, shall use the multi-service network deployed for the HHR project. AFC information security shall be included in the data exchanged over the network, and not in the communication network itself.

Authorization procedures, reliable data, etc, rely on certificates and signatures based on secret keys available for the concerned entities.

For bank information, such as authorization, black listing, payment data gathering etc, the security data is included in the protocols of the local credit-card responsible entity.

7.6.1 I NTERFACE 0-1–M EDIA-E QUIPMENT

This interface shall be compliant with the applicable standards.

7.6.2 I NTERFACE 1-2–E QUIPMENT-SCU

Communications between Equipment and SCU use the multi-service network inside a station. This network offers Ethernet port (RJ 45) 10/100 Base TX.

The interface should use TCP/IP protocols.

7.6.3 I NTERFACE 2-3–SCU-AFC C ENTRAL S ERVER

Communications between SCU and AFC Central Server use the multi-service network along the line. This network offers Ethernet port (RJ 45) 10/100 Base TX.

The interface should use TCP/IP protocols.

Req 13 Complete and detailed documentation of Interface 2-3 shall be provided.

7.6.4 I NTERFACE 3-4–AFC C ENTRAL S ERVER-C LEARING H OUSE

If it is used, this interface uses WAN connections.

Req 14 Complete and detailed documentation of Interface 3-4 shall be provided.

7.7 Architecture Diagram

An example of architecture for the AFC system is given in the diagram below. This diagram is given as an indication only and shall not be considered as a system requirement. The Consortium shall be fully responsible for the design and for proposing the final architecture of the AFC system.
