3. Function description: continue to provide leadership and define future strategy of the largest network
in Belgium
As Banksys S.A.was taken over by Atos WoldLine, Ioan continuted in his management position and
with his team,in collaboration with his French and German colleagues, in addition to their previous
assignements, they worked at the networking integration between the various corporate network
infrastructures.
Started already in 2005 as a proactive project, given the change of share-holders, the team managed by
Ioan worked at the migration of the terminal acquiring network (413 POPS in Belgium, 10.500 LL,
530.000 PSTN calls daily) to a new network using as POPS physical locations the Belgacom LEXes
and not bank branches, in line with Telco regulation rules as defined in Belgium. That offered him the
possibility to investigate and acquire experience with various telecommunication regulation rules and
legal obligations, closely working with various Telco while implementing POPS moves. Depending on
financial constrain, and legal requirements the network topology was adapted while keeping the
availability KPI at the top level as required by the management and reducing OPEXcosts.
In addition, given the European ambitions of the new company, Ioan together with his team works at
the possible European extensions of the current B2C and B2B network existing in Belgium using the
European experience of the B2B existing network developed by Banksys S.A. for SiNSYS.
