One of the biggest APAC international carriers, had planned to keep using their ATM/SDH (Ex-Alcatel) legacy network for three more years but the OEM could not offer a cost-effective solution for such legacy technology. This network includes the Network Management System with 16 servers replicated, a total of 32 servers, composed by five network management applications. The Network is composed by more than 27000 nodes covering SDH, DWDM, Ethernet over SDH, MPLS and ATM technologies.
As the customer already had a solution for L1 and L2 support and also had their hardware needs covered, by ramping down the network they decided to approach for a reliable partner to provide L3 technical support, on HW and software.
Despite the time zone difference, in less than 30 days Carritech along with a local partner from APAC started to provide an ongoing 24×7 support with the same demanding SLA as the OEM, that is defined as Gold Service. This includes several engineers permanently on call and an average resolution of 10+ tickets per month.
