Introduction The cable industry in Europe and across other Global regions has already deployed broadband cable television Hybrid Fibre Coax (HFC) data networks running the DOCSIS or EuroDOCSIS Cable Modem Pr
6、otocol. The Cable Industry is in the rapid stages of deploying IP Voice and other time critical multimedia services over these broadband cable television networks. The cable Industry has recognized the urgent need to develop ETSI Technical Specifications aimed at developing interoperable interface s
7、pecifications and mechanisms for the delivery of end to end advanced real time IP multimedia time critical services over bi-directional broadband cable networks. IPCablecom is a set of protocols and associated element functional requirements developed to deliver Quality of Service (QoS) enhanced sec
8、ure IP multimedia time critical communications services using packetized data transmission technology to a consumers home over the broadband cable television Hybrid Fibre/Coaxial (HFC) data network running the Cable Modem protocol. IPCablecom utilizes a network superstructure that overlays the two-w
9、ay data-ready cable television network. While the initial service offerings in the IPCablecom product line are anticipated to be Packet Voice, the long-term project vision encompasses packet video and a large family of other packet-based services. The Cable Industry is a global market and therefore
10、the ETSI standards are developed to align with standards either already developed or under development in other regions. The ETSI Specifications are consistent with the CableLabs/PacketCable set of specifications as published by the SCTE. An agreement has been established between ETSI and SCTE in th
11、e US to ensure, where appropriate, that the release of PacketCable and IPCablecom set of specifications are aligned and to avoid unnecessary duplication. The set of IPCablecom ETSI specifications also refers to ITU-SG9 draft and published recommendations relating to IP Cable Communication. The whole
12、 set of multi-part ETSI deliverables to which the present document belongs specify a Cable Communication Service for the delivery of IP Multimedia Time Critical Services over a HFC Broadband Cable Network to the consumers home cable telecom terminal. IPCablecom also refers to the ETSI working group
13、program that must define and develop these ETSI deliverables. ETSI ETSI TS 101 909-18 V1.3.1 (2004-05) 7 1 Scope IPCablecom has defined a set of protocols and associated element functional requirements in the TS 101 909 series of documents. These have been developed to deliver Quality of Service (Qo
14、S), enhanced secure IP multimedia time critical communication services, using packetized data transmission technology to a consumers home over a cable television Hybrid Fibre/Coaxial (HFC) data network. To facilitate maintenance and future enhancements to support other real-time multimedia services
15、the TS 101 909 document series consist of multi-parts as detailed in TS 101 909-1 22. The present document ispart 18 of the IPCablecom TS 101 909 series. The present document defines an analogue POTS presentation of an IPCablecom Termination Point (E-MTA) intended to deliver 3,1 kHz voiceband servic
16、es equivalent to a Public Switched Telephone Network (PSTN) or equivalent network with short length 2-wire local loop. NOTE: To be clear throughout the present document, the term “CM/MTA“ will be used to denote an E-MTA. The objective of the present document is to specify the physical and electrical
17、 characteristics of the CM/MTA interfaces that are part of an analogue POTS presentation of an IPCablecom CM/MTA particularly suitable for use by new network operators, or by operators operating in several European countries. The present document specifies characteristics of the CM/MTA to enable it
18、to operate with most existing national PSTN Terminal Equipment (TE), and especially with PSTN TE designed according to the European standards for analogue presented TEs. The electrical conditions specified at the CM/MTA are sufficient to ensure satisfactory operation of the following functions of TE
19、: a) call control; b) transmission; c) dialling; d) ringing. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
