Full details of the entire series can be found in part 1 7. Introduction The Telecommunications industry in Europe an
20、d surrounding regions has started to deploy broadband IP access networks using both wired and wireless access technologies (sometimes referred to as Next Generation Networks (NGN). The initial rollout of these Broadband networks has been focussed on supporting both data and interactive content, howe
21、ver, there is now an urgent need to support IP Voice (Telephony over IP) and other time critical multimedia services over these broadband networks. In particular there is a need to support legacy ISDN Terminal Equipment, this fact is highlighted in TR 101 963 6, clause 5 relating to MTA Requirements
22、. Consequently in order to support the development of broadband networks and equipment with support for legacy ISDN terminals, the key functions and features of these terminals need to be sufficiently defined. All new systems, independent of their access technology, may enjoy the results of the pres
23、ent document. ETSI ETSI EG 201 973-3 V1.2.1 (2005-03) 6 1 Scope The present document describes the functional technical characteristics supported by PSTNs across the wider European market, in order to provide guidance to developers of broadband networks and equipment (e.g. IPCablecom embedded MTA, F
24、WA subscriber units) that support an ISDN terminal. The present document does not include any Safety or EMC aspects or requirements. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
