ded. It is important to take care not to end up with negative traffic numbers. For example: MOC = 75% (MTC = 15%). 'Subscribes to own network' is a relative value, with respect to MOC. If it is too high, say 44 %, then the absolute value, 33 % (44 % of 75 %), exceeds the value MTC = 15%! It should be remembered that the traffic distribution is changing as the network evolves. In the initial phases of a new network the number of 'subscribers to own network' is small and grows at the same pace as the growth of the own subscriber base. In some network cases, the amount of traffic per subscriber varies from site to site, from one network region to another. This needs to be taken into consideration for a more accurate modelling of the network. Country Specific Regulations It is important to become familiar with country specific regulations at an early stage of the whole planning process. Regulatory issues may impose certain restrictions on the planning of networks, sometimes requiring special solutions to meet the requirements. Yet at times the regulations provide tailored solutions for a given country and all operators need to adhere these. Results of Network Assessment The results of the network assessment phase are presented in a detailed report. This report may be listed as a deliverable. The network assessment report should include all the inputs already discussed as well as the following points: Description of the network planning limitations imposed by the existing network infrastructure, e.g. the current network has several hot spots with congestion and/or the majority of all traffic is handled by a limited number of switches. Description of the network development considerations for the long term. With regard to the longer term growth, the planning report should point out issues that may limit network expansion. Considerations introducing a higher network layer (for transit or signalling STPs) could be discussed. Outline the network growth strategies in terms of costs and customer strategies. Dimensioning pri
