6.0 Technical Requirements 6.1 Interface Specification

The interface specifications will be provided to all Parties to Switching Services as part of the NCS Interconnectivity requirements. All interface specifications will conform to the international ISO8583; 1993 standards. All NCS Partner Institutions will have to develop both Issuer and Acquirer Interfaces that comply with the NCS Interface Specification as described in the following documents:

A	BASE24-es_ISO_8583_1993_Host_External_Message_Manual.pdf	Dec 2006
B	BASE24_es_ISO_8583_1993_Host_Ext_Msg_Manual_Future_Up date_Feb-2007.pdf	Feb 2007

6.2 Communication And Message Protocol

The NCS ISO 8583; 1993 Host External Message is based on the standard external message developed by the International Standards Organization (ISO). It is a variable-length and variable-content message that can be configured differently, based on the type of message being sent. The NCS ISO Host Interface component creates and interprets external messages according to the specifications in the NCS Interface specification document. The NCS ISO 8583; 1993 host external message allows incoming and outgoing messages to be configured individually by a host, depending on the information the host chooses to send and receive. 1. The message format will be ISO 8583. Details are provided in the NCS Interface Specification document.

All Partner Institutions would maintain secure dedicated Virtual Private Network
TCP/IP data communication to the NCS.
The communication protocol will be TCP/IP. 4. The Hardware Security Module (HSM) Connectivity - TCP/IP 6.3 Connection to NCS by Institutions The Nigerian Central Switch project requires a secure connectivity to all existing Switches in Nigeria and future new entrants. A secure interconnectivity has to be established with the NCS, as specified in the NCS Secure Interconnectivity Requirements (Sept. 2007).

6.4 Security

Parties to Switching Services involved in card-operated devices, must be capable of providing secure hardware encryption/decryption of customer PINs and messages for onward transmission to the NCS network. PIN numbers will be 4 digits. PINs and messages of transactions must be hardware encrypted using keys provided by NIBSS.

7.0 Nigeria Central Switch (Ncs) Operations 7.1 The Ncs Minimum Transactions Standard

The following minimum transaction set must be supported by all switches in order to achieve interoperability: 7.1.1 POS Transaction Types

Purchase
Purchase Reversal
7.1.2 ATM Transaction Types
Withdrawal
Balance Enquiry
Reversal Transaction will be available for each

7.1.3 Transactions From Other Devices/Channels

Because the source of all transactions will be the Custom NCS Interface, the NCS will process all transactions which are presented in a format recognized by that interface, regardless of which type of device or channel was used to initiate the transaction at the acquiring switch. This will allow the system to process transactions from, for example, the internet, mobile phones, and IVR (interactive voice response) systems.

7.2 Modus Operandi

Transactions that route to or through the NCS for authorization do so in a series of transaction messages. Transaction processing through the NCS includes the following components, depending on the source of the transaction and the routing configuration:
Message Delivery (foundation)
16
Acquirer Interface or Channel Manager (business)Prefix (business)Router (business) Issuer Authorization and/or Issuer Interface (business) Journal (business) There are many different components involved in any one transaction. Those listed above provide a basic list of components for the NCS payment engine processing.

7.3 Off-Line Services

The NCS will not provide off line authentication or authorization of transactions. All authorizations shall come from the issuer.

7.4 Reports

The following reports are to be generated and circulated via secured online mode.

S/N	Description
1	Daily Activity Report By Source Switch; By Bank
2	Daily Activity Report By Destination Switch; By Bank
3	Interchange Fees By Switch; By Bank
4	Net Settlement Report By Switch; By Bank
5	Detailed transaction report
6	Audit trail / History report
7	Transaction volume and value by terminal type and location

8.0 Fees And Charges

The NCS shall be kept operational at all times and as a result; all participants in the network shall bear the joint responsibility of supporting its operations. NIBSS considers the opportunity of participants to share ATM/POS networks that do not belong to them and thereby reducing investments in building infrastructures as a huge cost saving benefit. The associated cost for the discharge of the functions of the NCS is as follows:

8.1 Joining Fees

All parties to the Switching Services joining the NCS will be required to pay a one off fee. It is expected that these joining fees will cater for the efforts in infrastructure installation and systems delivery as well as contributory license for the development of payment system in Nigeria.

8.2 Transaction Charges

The Transaction Charges are of two types; 1. Switching Charge - NIBSS will charge for every financial transaction that hits the NCS; as shown in the table below.

Device	Payer	Recovery Of Fee
ATM	Issuer	NCS to recover fee from Issuer, through NIBSS, monthly.
POS	Acquirer OR Acquirer network processor	NCS to compute fee monthly and recover such fee on 15th of following month from bank account nominated by paying acquirer processor, who would have recovered the fee upfront from acquirer.

Settlement Charge - NIBSS will charge for every settlement transaction which
normally is received on net basis.

Charges will be reviewed at regular interval by the Management of NIBSS and approved by the Board of Directors, to ensure continuous operations of The NCS for the benefit of all stakeholders.

8.3 Transaction Fees Payable To Device Owners

Fees payable to device owners shall be as agreed by individual card schemes. With respect to transactions at POS terminals, Acquirers/Users should agree with Device Owners, the amount payable to Device Owners while amount payable to ATM owners/acquirers shall be agreed between the Owners/Acquirers and the Users/Issuers. ATM Acquirer/Device owners are required to display applicable Transaction Fees clearly on their devices, and obtain cardholder's consent during transaction processing.

9.0 Service Level

The four basic design goals that govern the development of the NCS are:

Availability
Data Integrity
Performance and Scalability
Open Interfaces
It is therefore expected that all other connecting Partner Institutions must have similar architecture, as transactions are mission critical and pivotal to EFT processing. As a result, the following draft service levels are expected as a minimum requirement. The NCS would be available for transactions 24 hours and 7 days a week. The NCS system's performance will be measured in terms of: a) Up-Time b) Response Time The performance of the Partner Institutions systems will be measured by: a) Success Rates - successful transactions as a percentage of all transactions switched to Partner Institutions for authorization.

b) Response Times The NCS would maintain an uptime of at least 99% during any 24 hour period, to all Partner Institutions. Partner Institutions connected to the NCS as Issuers must achieve transaction success rates of at least 97% any 24-hour period. For all transaction requests routed to authorizing institutions a timeout period will be set after which the institution node will be deemed to be down and the transaction will be classified as a failed transaction and declined. This period will be agreed with the authorizing institution but will be no longer than 90 seconds. The NCS will be responsible for maintaining and distributing all statistics relevant to the above. All NCS Partner Institutions will conform to these and other performance standards, which may be agreed from time to time. All NCS Partner Institutions will maintain and provide audit trails for all transactions which pass between their systems and the NCS for a minimum of 7 years. The timeout parameters on every terminal that allows access to the NCS must be no less than 40 seconds and not more than 90 seconds.

10.0 Settlement 10.1 Business Day

A Business Day for the NCS will be a 24-hour period. A typical business day will start from 12.00.00am to 11.59.59 pm.

10.2 Transaction Settlement Procedure

Inter Bank Engine.
The NCS end-of-day processing cycle will commence 12.00am, at the close of each
Business Day.
A Settlement report file consisting of the net position of each Partner Institution will be
generated.
The Settlement report file will be sent to Partner Institutions in a secure electronic
format.
Postings to the CBN accounts will take place once a day at the close of business.

10.2.1 Settlement During Weekends/Non Working Days

1. Transaction settlement will be done every day except on weekends and/or public
holidays or non working days. However, Settlement Report Files will be generated every day including weekends and on non working days 2. Settlement Report Files generated for each non working day will be processed on the next working day.

3. NIBSS will send settlement confirmation reports to Partner Institutions, confirming the
settlement (or non settlement) of daily transactions

10.3 Settlement Of Transactions 10.3.1 Settlement Risk Mitigation

Settlement risk shall be mitigated by the Proactive Risk Management (PRM) functionality
of the NCS.
The switches shall ensure that member banks in their scheme pledge securities that
provide for 110% protection for their operations.
