Digital telephony is the use of digital electronics in the provision of digital telephone services and systems. Since the 1960s a digital core network has almost entirely replaced the old Analog signal analog system, and much of the access network has also been digitized. Digital telephony was introduced to provide voice services at lower cost, but was then found to be of great value to new network services such as ISDN that could use digital facilities to transfer data speedily over telephone lines. Milestones in digital telephony This is a highly compressed list of milestones in digital telephony, in roughly chronological order.

refimprove date November 2011 Cable telephony is a form of digital telephony over cable TV networks. A telephone interface installed at the customer s premises converts analog signals from the customer s in home wiring to a digital signal, which is then sent over the cable connection to the company s switching center. The signal is then sent on to the public switched telephone network PSTN . Cable telephone provides another revenue stream for cable television system operators and gives the consumer the convenience of a single bill for combined television, internet and telephone services. ref name RG00 Richard Grigonis ed Cable Telephony in Computer Telephony Encyclopedia , Focal Press, 2000 pp.68 69 ref Emergency calls The biggest obstacle to cable telephone service is the need for nearly 100 reliable service for emergency call s. PacketCable , one of the emerging standards being developed for digital cable telephony, seems to be the most promising and able to work with the quality of service demands of Plain old telephone service traditional analog telephone service . Advantage The biggest advantage to digital cable telephone service is similar to the advantage of digital cable television, namely that data can be compressed, resulting in much less bandwidth used than a dedicated analog circuit switched service. Other advantages include better voice quality and perhaps future integration to a VoIP network providing cheap or unlimited nationwide and international calling. In most cases, digital cable telephone service is separate from broadband Internet access service being offered by many cable companies and does not rely on IP traffic or the Internet . Disadvantage The biggest disadvantage to digital cable telephone service is similar to the disadvantage of cable Internet access , namely that the medium is shared, resulting in occasional delays and drops when high volumes ...

The 3GPP next generation network NGN IP Multimedia Subsystem IMS multimedia telephony service MMTel is a global standard based on the IMS, offering converged, fixed and mobile real time multimedia communication using the media capabilities such as voice, real time video, text, file transfer and sharing of pictures, audio and video clips. With MMTel, users have the capability to add and drop media during a session. You can start with chat, add voice for instance Mobile VoIP , add another caller, add video, share media and transfer files, and drop any of these without losing or having to end the session. The MMTel standard is a joint project between the 3GPP and ETSI TISPAN standardization bodies. The MMTel standard is today the only global standard that defines an evolved telephony service that enables real time multimedia communication with the characteristics of a telephony service over both fixed broadband, fixed narrowband and mobile access types. MMTel also provides a standardized network to network interface NNI . This allow operators to interconnect their networks which in turn enables users belonging to different operators to communicate with each other, using the full set of media capabilities and supplementary services defined within the MMTel service definition. One of the main differences with the MMTel standard is that, in contrast of legacy circuit switched telephony services, IP transport is used over the mobile access. This means that the mobile access technologies that are in main focus for MMTel are access types such as high speed packet access HSPA , 3GPP long term evolution LTE and EDGE Evolution that all are developed with efficient IP transport in mind. MMTel allows a single SIP session to control virtually all MMTel supplementary services and MMTel media. All available media components can easily be accessed or activated within the session. Employing a single session for all media parts means that no additional sessions need to be set up to activate ... more details

In 1982, STC withdrew from System X and, in 1988, the telecommunications divisions of GEC & Plessey merged to form Marconi Communications GPT , with Plessey subsequently being bought out by GEC & Siemens AG Siemens . In the late 1990s, GEC acquired Siemens 40 stake in GPT and, in 1999, the parent company of GPT, GEC, renamed itself Marconi Electronic Systems Marconi . When Marconi was sold to Ericsson in January 2006, telent telent plc retained System X and continues to support and develop it as part of its UK services business. Implementation The first System X unit to enter public service was in September 1980 and was installed in Baynard House , London and was a tandem junction unit which switched telephone calls amongst 40 local exchanges.

In the interest in forming a trans Europe Telephone numbering plan numbering plan as an option or then future movement for anyone needing multi national European telephone presence, the International Telecommunication Union ITU allocated country calling code 388 as a subdivided, catch all container for such services. This was designated the European Telephony Numbering Space or ETNS . Although some ETNS numbers were assigned, few phone companies supported connecting calls to ETNS. ref http www.voip info.org wiki view 3883 http www.voip info.org wiki view 3883 ref Because of limited support, and the belief that the need for ETNS was superseded by Uniform Resource Identifier URI s, ETNS was suspended in 2005 and abolished in 2008. All ETS numbers were cancelled by the beginning of 2010. The 388 code is scheduled to be reclaimed by the ITU at the end of 2010. ref http www.ero.dk etns http www.ero.dk etns ref See also list of country calling codes . Allocation area Geographically the 388 country code was an overlay on top of all the pre existing, state bounded country codes of the countries in Europe. Among special country codes, 388 was unique in that it was both supranational yet geographically bounded other special codes, such as Global mobile satellite system 881 and freephone UIFN 800 , are completely international . Instead of being subdivided geographically as in a typical numbering plan, the ETNS was intended to be subdivided by type of service or customer. It would therefore not have been possible to Reverse engineering reverse engineer the location of an owner of an ETNS number based on the characteristics of the phone number. The numbers were also not allocated in blocks to individual carrier companies and were therefore intended to be portable. Carriers needed to have ETNS translation capability, or routing agreement with a carrier that did, in order for its customers to successfully call ETNS numbers.
