Direct distance dialing ( DDD ) is a telecommunications service feature in North America by which a caller may, without operator assistance , call any other user outside the local calling area. Direct dialing by subscribers typically requires extra digits to be dialed as prefixes to the directory telephone number of the destination. International Direct Distance Dialing (IDDD) extends the system beyond the geographic boundaries of the North American Numbering Plan (NANP).
110-691: The first direct-dialed long-distance telephone calls were possible in the New Jersey communities of Englewood and Teaneck . Customers of the ENglewood 3, ENglewood 4 and TEaneck 7 exchanges, who could already dial telephone numbers in the New York City area, could place calls to eleven major cities across the United States by dialing the three-digit area code and the seven-digit directory number. Local telephone numbers still consisted of
220-421: A stepping switch . The No. 1 Crossbar pioneered the link principle, with each individual switch able to handle as many phone calls as it had inputs or outputs, typically ten. This innovation diminished the cost of switches, at the expense of more complex controls. The complexity of the circuitry challenged the art of circuit drawings, leading to the development of detached contact drawings , which in turn led to
330-414: A bill interpreting the constitution to mean universal white male suffrage , excluding paupers; the constitution was itself an act of the legislature and not enshrined as the modern constitution. On February 15, 1804, New Jersey became the last northern state to abolish new slavery and enacted legislation that slowly phased out existing slavery. This led to a gradual decrease of the slave population. By
440-586: A few both-way, and some only for tandem traffic within the metropolitan area. Specialization was less marked in less dense areas. XBT served local telephone companies until the late 20th Century when they were replaced by 4ESS switches or other digital switches. The No. 1 Crossbar inspired the No. 5 Crossbar switch which intensified the trend towards greater efficiency and complexity. No. 5. Crossbar installations seldom replaced No. 1 systems, but were operated side by side with them, or in towns not large enough to warrant
550-517: A higher proportion of immigrants. New Jersey is home to roughly half a million unauthorized immigrants , comprising an estimated 6.2% of the population, which in 2018 was the fifth-highest percentage of any U.S. state. The municipalities of Camden, Jersey City, and Newark are considered sanctuary cities for illegal immigrants. For further information on various ethnoracial groups and neighborhoods prominently featured within New Jersey, see

New Jersey was among the Thirteen Colonies that supported the American Revolution , hosting several pivotal battles and military commands in the American Revolutionary War . New Jersey remained in the Union during the American Civil War and provided troops, resources, and military leaders in support of the Union Army . After the war, the state emerged as
770-420: A light beam. CTS machines were called 4A (Advanced) if the translator was included in the original installation, and 4M (Modified) if it was added later. A 1970s version of 4XB , the 4A/ETS, used a computer to translate. For international dialing, Traffic Service Position System (TSPS) provided the extra computer power. The reach of DDD was limited due to the inefficiency and expense of switching equipment, and
880-547: A major manufacturing center and a leading destination for immigrants, helping drive the Industrial Revolution in the U.S. New Jersey was the site of many industrial, technological, and commercial innovations . Many prominent Americans associated with New Jersey have proven influential nationally and globally, including in academia, advocacy, business, entertainment, government, military, non-profit leadership, and other fields. New Jersey's central location in

Echoing historical trends, the state has increasingly re-urbanized, with growth in cities outpacing suburbs since 2008. New Jersey is one of the most educated, affluent, healthy, diverse and highly developed states in the U.S., ranking it high in several quality of life metrics. As of 2022, New Jersey had
1100-799: A major industry, especially the Sterling Hill Mine . New Jersey prospered through the Roaring Twenties . The first Miss America Pageant was held in 1921 in Atlantic City ; the Holland Tunnel connecting Jersey City to Manhattan opened in 1927; and the first drive-in movie was shown in 1933 in Camden . During the Great Depression of the 1930s, the state offered begging licenses to unemployed residents,
1210-431: A maximum of 10,000 lines per office. Multifrequency terminating senders accomplished the same goal by accepting a fifth digit to discriminate among office codes served by the same office. The originating marker told the sender to delete the first two of seven digits in these cases. Sometimes the two office codes had the same third digit, in which case the first three digits for the "B" office were deleted and replaced with

The aircraft carrier USS Enterprise (CV-6) was briefly docked at the Military Ocean Terminal in Bayonne in the 1950s before she was sent to Kearney to be scrapped. In 1962, the world's first nuclear-powered cargo ship, the NS Savannah , was launched at Camden. In 1951,
1540-499: A native Philadelphian, had New Jersey ties and formally resided in New Jersey at the time; he later became Governor of New Jersey (1878–81). (In New Jersey, the factions of the Democratic party managed an effective coalition in 1860.) During the American Civil War , the state was led first by Republican governor Charles Smith Olden , then by Democrat Joel Parker . During the course of the war, between 65,000 and 80,000 soldiers from
1650-561: A number of the Caribbean Islands ). Some subscribers could already directly dial transatlantic telephone calls to certain destinations as early as in 1957 over the recently completed Atlantic cable to England. A new systematic extension of Direct Distance Dialing was developed and was introduced as International Direct Distance Dialing ( IDDD ) in March 1970. With so much new equipment already working that could not handle more than
1760-473: A single digit, indicated as AR for Arbitrary, usually a zero. The potential for five incoming digits to address a 100,000 line office was not exploited. The No. 1 Crossbar system consolidated maintenance and testing activities into a single area of the central office, sometimes known as the MTC or "Maintenance Test Center". Whereas earlier systems, such as the panel switch had maintenance facilities spread throughout
1870-491: A subscriber lifted their phone off the hook, they were connected to an originating (also known as a s ubscriber's ) sender. This sender received and registered the dialed digits, communicated with an originating marker to establish the path for the call, and then pulsed the dialed digits forward to the terminating office in whatever format was required. In many cases, No. 1 Crossbar central offices could have in excess of 100 subscriber's senders, as each sender only served one call at
1980-410: A switch had ANI, it could not identify callers on party lines . This was only partly overcome by tip-party identification for two-party lines. As the cost of subscriber line carrier declined, party lines were gradually phased out. As this and other improved technologies became available, as well as Automatic Message Accounting (AMA) computers to process the long-distance records into customer bills,
2090-442: A time. When the call setup stage was complete, the sender returned to normal and awaited seizure by another caller. In the terminating half of the crossbar office, a terminating sender link circuit connected a terminating sender to the trunk, in order to receive the information from the originating sender. This was typically done using Revertive Pulse, as in the panel switch . Multi-frequency terminating senders were introduced in
2200-523: A trunk through the long-distance network to the gateway office, which sent a second wink to the originating office, which then sent the whole dialed number. Thus the toll switching system needed no modification except at the gateway. The international trunks used Signaling System No. 5 , a "North Atlantic" version of the North American multi-frequency signaling system, with minor modifications including slightly higher digit rate. European MF systems of

The state ranked eleventh in the country by total population and first in population density, with 1,185 residents per square mile (458 per km ). Historically, New Jersey has experienced one of the fastest growth rates in the country, with its population increasing by double digits almost every decade until 1980; growth has since slowed but remained relatively robust until recently. In 2022,
2970-406: The 2010 United States census , only four municipalities had over 100,000 residents (although Edison and Woodbridge Township came very close); this number increased to seven by the 2020 census. Residents of New Jersey are most commonly referred to as New Jerseyans or, less commonly, as New Jerseyites. According to the 2020 U.S. census , the state had a population of 9,288,994, a 5.7% increase since
3080-699: The American Civil War 's end, about a dozen African Americans in New Jersey were still held in bondage. New Jersey voters eventually ratified the constitutional amendments banning slavery and granting rights to the United States' black population. Industrialization accelerated in the present-day North Jersey region of the state following completion of the Morris Canal in 1831. The canal allowed for anthracite coal to be transported from eastern Pennsylvania 's Lehigh Valley to North Jersey's growing industries in Paterson , Newark , and Jersey City . In 1844,

The Dutch were the first Europeans to lay claim to lands in New Jersey. The Dutch colony of New Netherland consisted of parts of the modern Mid-Atlantic states. Although the European principle of land ownership was not recognized by the Lenape , Dutch West India Company policy required its colonists to purchase land that they settled. The first to do so
3630-690: The Golden Gate , while calls with destinations in Oakland and the East Bay continued to use area code 415. When the electromechanical card-translator box became available sometime during 1952–53, six-digit translation became possible and the use of area code 318 was no longer required. Area code 318 was reclaimed for future use (now used as an area code for northern Louisiana ), and the entire San Francisco Bay Area returned to using area code 415. The No. 4 Crossbar switching system had been introduced in

The U.S. Census Bureau divides New Jersey's 21 counties into seven metropolitan statistical areas , with 20 counties included in either the New York City or Philadelphia Combined Statistical Area . Warren County
6160-447: The application of Boolean algebra and Karnaugh maps . In an originating marker, a cross connect field had a terminal for each two- or three-digit office code. A particular office code terminal was cross connected to the coil of a route relay. When the office code point was grounded, it operated the route relay, whose contacts were wired in another cross connect or data field. These cross connects were in turn used to activate relays in

In many cases the resulting Crossbar tandem switch (XBT) replaced a Panel Sender Tandem, because its multi-frequency senders were able to receive seven digits and some were modified to accept ten. Sometimes it replaced an Office Select Tandem as well, since its Revertive Pulse senders were able to accept Office Brush and Group parameters. In big cities, some XBT were strictly incoming Class 4 telephone switches , some outgoing,

According to HUD 's 2022 Annual Homeless Assessment Report , there were an estimated 8,752 homeless people in New Jersey. The top countries of origin for New Jersey's immigrants in 2018 were India , Dominican Republic , Mexico , Ecuador , and
8030-484: The limited ability to process records of completed calls. An early obstacle was that the majority of switching systems did not provide Automatic Number Identification (ANI). Common control switches, such as the 1XB switch , were fairly quickly retrofitted to provide ANI, and most 5XB switches were initially installed with ANI services. Panel switch were eventually retrofitted, as were some step-by-step systems that were not scheduled for immediate replacement. Even if
8140-405: The line. The revertive pulse system as used in 1XB had a "High Five" feature by which the "incoming brush" selection could be incremented by five. Thus, the new IB numbers 6 through 10 designated a second ten thousand telephone numbers, known as a "B" office. This allowed each 1XB incoming section to handle twenty thousand lines, whereas a panel office using the revertive pulse system could handle
8250-416: The link frames as necessary, and provided functions including supervision, signaling, and control. Examples of these frames included district junctors , subscriber senders , and originating and terminating markers . Unlike the motor driven, clutch controlled panel switch selectors, crossbar switches using the link principle required originating and terminating markers to find an idle path and set up
8360-407: The marker that controlled the treatment, or handling for the office code dialed. Using the output provided by its decoding stage, the originating marker could select two office link frames to search for idle trunks to the destination. Once the originating marker established a path to the called office, it returned pulsing information to the subscriber sender. The sender then sent the remaining digits of
8470-419: The most populous is Hackensack , with 46,030 residents. Many urban areas extend far beyond the limits of a single large city, as New Jersey municipalities tend to be geographically small; three of the four largest cities in New Jersey by population have under 20 square miles (52 km ) of land area, and eight of the top ten, including all the top five, have a land area under 30 square miles (78 km ). As of
8580-495: The necessary toll switching equipment, or because they still did not use a seven-digit local numbering plan. Montreal , Quebec , and Toronto , Ontario , in Canada, for example, had a mix of six- and seven-digit telephone numbers from 1951 to 1957, and did not have DDD until 1958. Whitehorse , Yukon , had seven-digit numbers starting in 1965, but the necessary switching equipment was not in place until 1972. San Francisco required
8690-422: The next few years were installed with IDDD as original equipment, and in the 1970s ESS offices also provided the service. The key to the new system was two-stage multi-frequency pulsing. The outgoing sender sent its Class 4 toll center an off-hook signal as usual, received a wink as usual as a "proceed to send" signal, and outpulsed only a special three-digit (later six-digit) access code. The toll center picked
8800-417: The northeastern United States. Hurricanes and tropical storms , tornadoes , and earthquakes are rare; the state was impacted by a hurricane in 1903 , Tropical Storm Floyd in 1999 , and Hurricane Sandy in 2012 , which made landfall in the state with top winds of 90 mph (145 km/h). Climate change is affecting New Jersey faster than much of the rest of the United States. Climatologists at
8910-578: The northwest of the state, to 7B near Cape May. All-time temperature extremes recorded in New Jersey include 110 °F (43 °C) on July 10, 1936, in Runyon , Middlesex County and −34 °F (−37 °C) on January 5, 1904, in River Vale , Bergen County. Average annual precipitation ranges from 43 to 51 inches (1,100 to 1,300 mm), spread uniformly throughout the year. Average snowfall per winter season ranges from 10–15 inches (25–38 cm) in
9020-497: The office, it was found desirable to centralize these processes into a single space so that technicians could work more effectively. This decision was also driven by the use of markers, which carried out their individual tasks quickly, and interfaced with several other circuits while doing so. Because of the nature of their rapid operation, and the importance of consistency and correctness, both originating and terminating equipment had trouble indicators which illuminated lamps to indicate
9130-451: The originating marker was route advance , where if all trunks were busy, the marker would operate a different route relay to select an alternate route via a tandem. This feature kept trunk groups small, and more heavily loaded with traffic, thus saving cost in outside plant . Number 1 Crossbar offices made use of complex and versatile originating and terminating senders to communicate within themselves, and to other switching offices. When
9240-449: The reach of DDD was slow in the 1950s, but quickened in the early 1960s. Electronic switching systems allowed electronic processing of the dialed digits, referring to electronic memories to determine call routing, and this has reached the state of the art, with digital telephone exchanges which are basically specialized computers that route voice traffic from one "peripheral" to another as digital data. Call routing can now be done based on
9350-680: The requisite ten-digit telephone numbers of DDD, the new system was based on designs by which most toll offices did not have to store and forward the whole international telephone number. Gateway offices were set up in New York, London and Paris, connected to the ordinary automatic toll network. The New York gateway was at 32 Avenue of the Americas . The new LT1 5XB switch on the tenth floor of 435 West 50th Street received new originating registers and outgoing senders able to handle fifteen-digit telephone numbers, with appropriate modifications to completing markers and other equipment. Other 5XB switches in
9460-533: The second state constitution was ratified and brought into effect. Counties thereby became districts for the state senate, and some realignment of boundaries (including the creation of Mercer County ) immediately followed. This provision was retained in the 1947 Constitution, but was overturned by the Supreme Court of the United States in 1962, by the decision Baker v. Carr . While the Governorship
9570-645: The signing of the Treaty of Paris , which ended the war. On December 18, 1787, New Jersey became the third state to ratify the United States Constitution , which was overwhelmingly popular in New Jersey since it prevented New York and Pennsylvania from charging tariffs on goods imported from Europe. On November 20, 1789, New Jersey became the first in the newly formed Union to ratify the Bill of Rights . The 1776 New Jersey State Constitution gave
9680-497: The source and nature of trouble when it occurred. This allowed technicians to quickly identify and resolve issues with the equipment without taking it out of service to perform lengthy troubleshooting routines. Because it was often necessary to run tests on other equipment while locating the source of trouble, other test frames were located near the trouble indicators. Maintenance facilities were standardized in No. 1 Crossbar offices, so most maintenance centers contained one or more of
9790-494: The south and near the seacoast, 15–30 inches (38–76 cm) in the northeast and central part of the state, to about 40–50 inches (1.0–1.3 m) in the northwestern highlands, but this often varies considerably from year to year. Precipitation falls on an average of 120 days a year, with 25 to 30 thunderstorms, most of which occur during the summer. During winter and early spring, New Jersey can experience nor'easters , which are capable of causing blizzards or flooding throughout
9900-478: The southwestern counties of the state, which reside within the Delaware Valley surrounding Philadelphia . Despite its heavily urban character and a long history of industrialization , forests cover roughly 45 percent of New Jersey's land area, or approximately 2.1 million acres (8,500 km ), ranking 31st among the 50 U.S. states and six territories. Northwestern New Jersey, often referred to as
10010-459: The special area code 318 due to temporary routing requirements. San Francisco and Oakland each had their own separate toll-switches, so calls had to be routed accordingly depending on the final destination. As the telephone equipment used at the time could only handle three-digit translation, the temporary use of area code 318 was required to distinguish between the two areas. Area code 318 was temporarily used to specify San Francisco and areas north of
10120-545: The state enlisted in the Union army; unlike many states, including some Northern ones, no battle was fought there. In the Industrial Revolution , cities like Paterson grew and prospered. Previously, the economy had been largely agrarian, which was problematically subject to crop failures and poor soil. This caused a shift to a more industrialized economy, one based on manufactured commodities such as textiles and silk. Inventor Thomas Edison also became an important figure of
10230-429: The state's ethnic makeup was as follows: 71.9% White alone, 15.1% Black or African American alone, 10.0% Asian alone, 0.6% American Indian and Alaska Native alone, 0.1% Native Hawaiian and Other Pacific Islander alone, and 2.3% Two or more races. Hispanic or Latino accounted for 20.9%, while White alone (non-Hispanic or Latino) accounted for 54.6% of the population. Many of the municipalities in Bergen County, New Jersey ,
10340-458: The state's largest county, have a sizeable minority population of Hispanics and Asians. 1XB switch The Number One Crossbar Switching System ( 1XB ), was the primary technology for urban telephone exchanges served by the Bell System in the mid-20th century. Its switch fabric used the electromechanical crossbar switch to implement the topology of the panel switching system of
10450-437: The state's median household income was over $ 85,000 compared to the national average of roughly $ 65,000. Conversely, New Jersey's poverty rate of 9.4% was slightly lower than the national average of 11.4%, and the sixth lowest of the fifty states, Washington, D.C., and Puerto Rico . This is attributed to several factors, including the state's proximity to the major economic centers of New York City and Philadelphia , its hosting
10560-434: The state, but temperatures can, for brief periods, fall below 10 °F (−12 °C) and sometimes rise above 50 °F (10 °C). Northwestern parts of the state have significantly colder winters with sub-0 °F (−18 °C) being an almost annual occurrence. Spring and autumn may feature wide temperature variations, with lower humidity than summer. The USDA Plant Hardiness Zone classification ranges from 6 in
10670-418: The switch train for each call. A marker, being a complex control instrument with a short holding time, had the task of decoding the digits of the seven-digit telephone number to determine the routing required to set up the switching fabric for call completion. Earlier crossbar exchanges had used the crossbar switch according to the selector principle, with one input and typically 100 or 200 outputs, similar to
10780-418: The terminating section, where the last 4 or 5 digits of the telephone number were used to determine the location of the called line. Despite the division of the system into two logical halves, the No. 1 Crossbar placed all subscriber lines on one of several line link frames, which were used for both origination and termination. This simplified administration and reduced the number of frames required, compared to
10890-547: The time used compelled signaling , which would slow down too much on a long transoceanic connection. In the 1970s, toll centers were modified by adding the Traffic Service Position System (TSPS). With these new computers in place, digit storage in the toll system was no longer a problem. End offices were less extensively modified, and sent all their digits in a single stream. TSPS handled the gateway codes and other complexities of toll connections to
11000-470: The vote to all inhabitants who had a certain level of wealth. This included women and Black people, but not married women because they were not legally permitted to own property separately from their husbands. Both sides, in several elections, claimed that the other side had had unqualified women vote and mocked them for use of petticoat electors, whether entitled to vote or not; on the other hand, both parties passed Voting Rights Acts. In 1807, legislature passed
11110-426: The way up to the termination point at the line link frame (LLF). Notably, this design meant that interoffice calls were handled in the same basic way as intra office calls. No distinction was made between calls terminating in the same office, or a different crossbar office. Any originating call that was to terminate on the same machine would pass through the entire originating section, then a trunk would be selected to
11220-577: The west by Pennsylvania across the Delaware River . New Jersey is broadly divided into the North , Central , and South Jersey geographic regions, although some residents do not consider Central Jersey a region in its own right. Across the regions are five distinct areas divided by natural geography and population concentration. Northeastern New Jersey, often referred to as the Gateway Region , lies closest to Manhattan in New York City, and up to
11330-865: The zeppelin airship Hindenburg crashed in flames over Lakehurst , and the SS Morro Castle beached itself near Asbury Park after going up in flames while at sea. Through both World Wars , New Jersey was a center for war production, especially naval construction. The Federal Shipbuilding and Drydock Company yards in Kearny and Newark and the New York Shipbuilding Corporation yard in Camden produced aircraft carriers , battleships, cruisers, and destroyers. New Jersey manufactured 6.8 percent of total United States military armaments produced during World War II , ranking fifth among
11440-436: Was Michiel Pauw , who established a patron ship called Pavonia in 1630 along North River , that eventually became Bergen . Peter Minuit 's purchase of lands along the Delaware River established the colony of New Sweden , that lasted until the Dutch conquered it in 1655. Then the entire region became a territory of England on June 24, 1664, after an English fleet under command of Colonel Richard Nicolls sailed into what
11550-556: Was also a leading industry during the middle to late 19th century. Bog iron pits in the New Jersey Pine Barrens were among the first sources of iron for the new nation. Mines such as Mt. Hope, Mine Hill, and the Rockaway Valley Mines created a thriving industry. Mining generated the impetus for new towns and was one of the driving forces behind the need for the Morris Canal . Zinc mines were also
11660-557: Was credited with a revitalization of Hudson County and Jersey City . Urban revitalization has continued in North Jersey in the 21st century. In 2014, Jersey City's Census-estimated population was 262,146, with the largest population increase of any municipality in New Jersey since 2010, representing an increase of 5.9% from the 2010 U.S. census , when the city's population was enumerated at 247,597. Between 2000 and 2010 Newark experienced its first population increase since
11770-569: Was named the Province of New Jersey . Since its inception, New Jersey has been characterized by ethnic and religious diversity . New England Congregationalists settled alongside Scots Presbyterians and Dutch Reformed migrants. While the majority of residents lived in towns with individual landholdings of 100 acres (40 ha), a few rich proprietors owned vast estates. English Quakers and Anglicans owned large landholdings. Unlike Plymouth Colony , Jamestown and other colonies, New Jersey
11880-556: Was populated by a secondary wave of immigrants who came from other colonies instead of those who migrated directly from Europe. New Jersey remained agrarian and rural throughout the colonial era, and commercial farming developed sporadically. Some townships, such as Burlington on the Delaware River and Perth Amboy , emerged as important ports for shipping to New York City and Philadelphia. The colony's fertile lands and tolerant religious policy drew more settlers, and New Jersey's population had increased to 120,000 by 1775. Settlement for
11990-535: Was ranked as the fourth most diverse state in 2024. New Jersey ranks near the top on both the American Human Development Index and the standard Human Development Index . According to climatology research by the U.S. National Oceanic and Atmospheric Administration , New Jersey has been the fastest-warming state by average air temperature over a 100-year period beginning in the early 20th century, which has been attributed to warming of
12100-494: Was stronger than under the 1776 constitution, the constitution of 1844 created many offices that were not responsible to him, or to the people, and it gave him a three-year term, but he could not succeed himself. New Jersey was one of the few Union states (the others being Delaware and Kentucky ) to select a candidate other than Abraham Lincoln twice in national elections, and sided with Stephen A. Douglas (1860) and George B. McClellan (1864) during their campaigns. McClellan,
