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 (QoS), enhanced secure IP multimedia time critical communication services, using packetized data transmission technology to a consumer's home over a cable television Hybrid Fibre/Coaxial (HFC) data network.

To facilitate maintenance and future enhancements to support other real-time multimedia services 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 services 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 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 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:

a) call control;

b) transmission;

c) dialling;

d) ringing.
