om tender to ready for service, enabling a consistent process for a particular contract. 'What is ordered should also be delivered'. Historically, the local exchange has been the main network element for the use of PTP at Ericsson. Later on the concept was adopted for other network solutions. With PTP it is also easier and faster to respond to an operator specification, particularly regarding the statement of compliance. 3.6.5 CONVERGING FP To a large extent the ongoing convergence is in fact a convergence between FPs. See Figure 3.22. 3.6.6 CONVERGING TELECOM, DATACOM AND MEDIA INDUSTRIES In principle three worlds collide: the telecom world, IP world and media world. To make the converged multimedia world work well there is a need for a kind of glue or mid- dleware. See Figure 3.23. This requires an additional part (sometimes implemented as a network: the service network) to cater for a proper utilization of the new possibili- ties offered by the media industry. The new network component implies a need for a coordinated development in the terminal devices and service networks.
