Public switched telephone network
The public switched telephone network (PSTN) is the concatenation of the world's public circuit-switched telephone networks, in much the same way that the Internet is the concatenation of the world's public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones.
The PSTN is largely governed by technical standards created by the ITU-T, and uses E.163/E.164 addresses (known more commonly as telephone numbers) for addressing.The basic digital circuit in the PSTN is a 64-kilobit-per-second channel, originally designed by Bell Labs, called a "DS0" or Digital Signal 0. To carry a typical phone call from a calling party to a called party, the audio sound is digitized at an 8 kHz sample rate using 8-bit pulse code modulation.
The DS0's are the basic granularity at which switching takes place in a telephone exchange. DS0's are also known as timeslots because they are multiplexed together in a time-division fashion. Multiple DS0's are multiplexed together on higher capacity circuits, such that 24 DS0's make a DS1 signal, which when carried on copper is the well-known, T-carrier system, T1 (the European equivalent is an E1, containing 32 64 kbit/s channels). In modern networks, this multiplexing is moved as close to the end user as possible, usually into cabinets at the roadside in residential areas, or into large business premises.
The timeslots are conveyed from the initial multiplexer to the exchange over a set of equipment collectively known as the access network. The access network and inter-exchange transport of the PSTN use synchronous optical transmission (SONET and SDH) technology, although some parts still use the older PDH technology.
Within the access network, there are a number of reference points defined. Most of these are of interest mainly to ISDN but one - the V reference point - is of more general interest. This is the reference point between a primary multiplexer and an exchange. The protocols at this reference point were standardised in ETSI areas as the V5 interface.
Only the very oldest and most backward parts of the telephone network still use analog technology for anything other than the last mile loop to the end user, and in recent years digital services have been increasing rolled out to end users using services such as DSL and ISDN.In the 1970s the telecommunications industry conceived that digital services would follow much the same pattern as voice services, and conceived a grandiose vision of end-to-end circuit switched services, known as the Broadband Integrated Services Digital Network (B-ISDN). The B-ISDN vision has been overtaken by the disruptive technology of the Internet.
Many observers believe that the long term future of the PSTN is to be just one application of the Internet - however, the Internet has some way to go before this transition can be made: see the article on Voice over IP for more on this subject.
The PSTN was the earliest example of traffic engineering to deliver Quality of Service guarantees. (See the work of A.K. Erlang for some history on this).

September is the ninth month of the year in the Gregorian Calendar and one of four Gregorian months with 30 days.
In Latin, septem means "seven" and septimus means "seventh"; September was in fact the seventh month of the Roman calendar until 153 BC, when there was a calendar reform from the month of the Ides of March to the Kalends, or January 1.[1]
September marks the beginning of the ecclesiastical year in the Eastern Orthodox Church.[citation needed] September begins on the same day of the week as December every year, because there are 91 days separating September and December, which is a multiple of seven (the amount of days in the week)Events in September

September, from the Très riches heures du duc de Berry

School starts in September in many countries, such as here, in Belgium (here is a photograph of the first school day in a school in Liège)
It is the start of the academic year in many countries in the Northern Hemisphere.
On the first Sunday of September, the regata storica parade is staged in Venice, as prelude to the rowing contests known as regattas.[citation needed]
Labor Day (Labour Day in Canada) is observed on the first Monday in September in the United States and Canada.
In India, Teachers' Day is celebrated on September 5. The date is the birthday of the second President of India, academic philosopher Dr. Sarvepalli Radhakrishnan.[citation needed]
In Japan, Respect for the Aged Day is a national holiday celebrated on the third Monday of September. Autumnal Equinox Day is also a national holiday.
In the United States, Hispanic Heritage Month is celebrated from September 15 to October 15.[2]
Peter Brock and Steve Irwin, two prominent Australians, both died in September.
In Mexico, Independence Day is celebrated September 15.[3]
In Brazil, Independence Day is celebrated September 7
In Saint Kitts and Nevis, National Heroes' Day is celebrated September 16.[4]
In Saint Kitts and Nevis, Independence Day is celebrated September 19.[5]
In Chile, Independence Day is celebrated September 18
National Grandparents' Day takes place on the first Sunday after Labor Day in the United States and Canada [6].
In the United States, September 11 is Patriot Day, in remembrance of the terrorist attacks on September 11, 2001.[7][8]
In the Netherlands the third Tuesday in September is known as prinsjesdag. The government presents its annual budget. The queen rides to the parliament in a gilded coach and reads the plans for the coming year to the States-general.[citation needed]
The equinox named the autumnal equinox in the northern hemisphere and the vernal or spring equinox in the southern hemisphere occurs on dates varying from 21 September to 24 September (in UTC). In the pagan wheel of the year the spring equinox is the time of Ostara and the autumn equinox is that of Mabon.[citation needed]
In KwaZulu-Natal, king Shaka is commemorated on the last Sunday of September.[citation needed]
Counterintuitively, the German Oktoberfest and the Chinese August Moon festival (more correctly called the Mid-Autumn Festival) both occur in September.
In New Zealand , Father's Day is celebrated on the first Sunday of September.[citation needed]
In Australia, Father's Day is celebrated on the first Sunday of September.[citation needed]
In Australia, the Rugby League Grand Final is played on the last Sunday of September.[citation needed]
In Australia, the AFL Grand Final is played on the last Saturday of September.[citation needed]
September 1 is celebrated as the beginning of Eritrea's 30 year armed struggle for independence from Ethiopia, which began in September of 1961 and ended in May of 1991. .
