The paper presents a realistic scenario for the introduction of a public ATM network to be implemented on the Hungarian SDH infrastructure. The Hungarian SDH network was deployed in 1996 with STM-4 rings on the lower level, and an STM-16 mesh subnetwork on the higher level, while the ATM network is intended to be introduced with two hierarchical levels: the(More)
The paper presents an approach for the topology design of a Hungarian public ATM network on top of the Hungarian SDH network with STM-4 rings on the lower level, and STM-16 mesh on the higher level. The approach is being implemented in the XPLANET tool developed for the support of the network planning activities of the Hungarian Telecommunications Company(More)
