 phisticated, easy-to-use information management functionality, routing facilities, and ma- nipulation of physical and logical networks as well as capacity and equipment type and size identification accordingly. Transmission Planner provides advanced support for planning and dimensioning of mo- bile, TETRA, PSTN and Data Operator's networks. SDH, primary rate (n X 2 Mbps) and generic data transmission as well switching and SS7 signalling networks planning are sup- ported. Mobile access transmission network planning (n x 2 Mbps) is supported in all details. Transmission Planner combines sophisticated design algorithms with an intuitive, easy- to-use graphical user interface. Design algorithms are useful but they cannot handle all INTEGRATED NETWORK PLANNING TOOL: NOKIA NETACT PLANNER 2G/3G TETRA Inter- Cellular module module module Switch Signaling module module module ATM module Primary Path module Detailed module VC-4 module Transport module (line systems) Alloc.

A user-friendly interface is important for visualisation and for manual modifications to provide maximal flexibility for the network planner. The Transmission Module supports efficient transmission network architecture planning in interactive sessions. Applications are available for key tasks, such as network topology and capacity manipulation with different traffic scenarios. It gives results of network capacity utilisation as well as information of non-routed traffic. As a result, the network topology and required transmission capacities are presented, as well as the number and size of nodes (see Figure A.5). The Transmission Module's Detailed-view provides a detailed level of information about the actual physical devices in 2G and 3G transmission networks. Other modules in transmission network layers are: IP, ATM, Lightpath, SDH, and PDH. The Traffic Module models all tra
