Worked for 12 months at Central Trustee Savings Bank (CTSB) as Technical Manager on the design and implementation of an extension to the bank’s existing CHAPS system. The new software enabled CTSB branch offices to link via their existing Branch Network to the London based TANDEM NonStop system and thence into the CHAPS network. This required implementing a IBM 2780 comms line-driver, automatic message authentication, remote/off-site logging and additional screen handling for the user interface. An initial 3 month period existed during which 4 Logica staff defined the new Branch Network Axcess (BNA) sub-system and a following phase involved 6 Logica staff and 2 client staff on the design, coding and testing of the new software. During the design phase was responsible for :-

The overall design approach for incorporating the new BNA extension with the existing system.

The overall design of the comms interface which linked the TANDEM with the Sperry Host/Branch network over an IBM 2780 comms link. This link implemented a single-threaded dialogue to the branches and a multi-threaded dialogue from them. It was designed with components for driving the comms link, handling payments/link dialogue from the branches, handling data received from the CHAPS Gateway for the branches, responding to TANDEM inter-process messages from both the user and the operating system, performing timeout & reporting functions, performing internal consistency, housekeeping and tracing functions.

 During the implementation phase, acted as Technical Manager with direct responsibility for :-

The technical design of the software and production of all deliverable system documents.

Scheduling programming activity and liaising with CTSB to ensure a consistent approach on overlapping areas between old/new software

The conducting of System Integration and Testing and co-ordinating of the production of ad-hoc software, testing tools

Assisting the project manager with project & QA planning, system design/sizing reviews, evaluation of change requests and of client produced Certification tests

Duplicated as team leader for the development of the branch link Communications Interface and the formulation of the ‘link protocol’

Designed/coded/tested the. Communications Link Interface’s kernel module, its 2780 Bisync driver and it’s CHAPS Inward message processing module. These were all coded in TAL.

On secondment to the Logica office in Rotterdam to work on the design and implementation of an O.S.I gateway, into an X25 banking network, for the RABO Bank. The custom built gateway ran on TANDEM Non-Stop 2/TXP hardware, implementing layers 4,5,6 Of the OSI reference model, with a user defined layer 7. It operated multiple sessions, handling the bi-directional flow of Tele-Giro payment traffic between RABO and the Dutch central banking organisation (BGC), via the Spoedcircuit network. The connection between the RABO Tandem computers and the BGC’s IBM Series 1 was via the Dutch X25 PSS network. The project was in 2 phases, an initial 3 months functional specification period and a subsequent design and implementation period. During the functional specification phase was responsible for

Performing a feasibility study into which of the various class of Transport Layer would be suitable for the project. Several technical notes were produced.

Specifying the overall hardware/software environment implementing the gateway

Producing the functional specification for a Class 2 transport layer protocol for the gateway

Producing the design specification for the Gateway’s Multi-Process Class 2 Transport layer

 During the implementation phase was responsible for :-

Designing the inter-process protocol which linked the multi-process Transport Layer. The resulting protocol ensured the synchronisation of the layers individual component processes both during normal operation and under process/processor failures.

Designed, coded (in TAL) and tested the Transport Circuit Process (TCP) which was the major component of the Transport Layer. A single TCP, which interfaced to the X25 network, was designed to handle 12 OSI Transport connections simultaneously on a single PVC. It performed message splitting/concatenation, TPDU recognition/routing and was responsible for the initiation of Transport Server provide aborts resulting form network resets or TPDU protocol error conditions.

Designed, coded (in TAL) and tested various TCP sub-systems which were intended to aid high throughput. These sub-systems included dynamic buffering, FIFO queue management and interprocess  message/reply management, all implemented as a run-time user-library and available for use by other processes within the gateway

Worked on the CHAPS 2 project, implementing the Banks-Specific software for Barclays Bank, on their TANDEM Non-stop 2 configuration. The TANDEM communicated with other banks’ systems via British Teleco’s PSS network and with Barclays Payments System using an X25 link/Barclays internal network. An addition communications link was established from the TANDEM with the Bank of Scotland, using IBM 3270 protocol. Work undertaken on the project included

Responsibly for initially installing Logica’s FASTRX Tp/Message switching software), around which the CHAPS  Bank’s Software (BSS) was written

Coded and tested an X25 communications interface (Line Handler). This interface handled the CHAPS message exchange over the X25 link with the bank’s Payment Process.  It was coded in TAL, utilising both TANDEM’s X25’s interface and the FASTRX software

Coded and tested a 3270 communications Line Handier to perform CHAPS message exchange with the Bank of Scotland’s IBM system. This task meant designing the interface I/O logic to handle IMS/VTAM activity over the link.

During the follow up support phase , acted as project manager. supervised a team of in providing support on FASTRX and all aspects of the BSS/TANDEM software
