CRAZY CROSSBAR CHALLENGE mit Bestrafung - MefYou

It was little used in America, but the Televerket Swedish governmental agency manufactured its own design the Gotthilf Betulander design from , inspired by the Western Electric system , and used it in Sweden from until the digitalization in the s in small and medium-sized A model switches.

In , a similar design by Swedish Televerket was installed in Sweden, making it possible to increase the capacity of the A model switch.

In , the Ericsson Swedish company developed their own versions of the 1XB and A systems for the international market.

Crossbar switching quickly spread to the rest of the world, replacing most earlier designs like the Strowger step-by-step and Panel systems in larger installations in the U.

Graduating from entirely electromechanical control on introduction, they were gradually elaborated to have full electronic control and a variety of calling features including short-code and speed-dialing.

In the UK the Plessey Company produced a range of TXK crossbar exchanges, but their widespread rollout by the British Post Office began later than in other countries, and then was inhibited by the parallel development of TXE reed relay and electronic exchange systems, so they never achieved a large number of customer connections although they did find some success as tandem switch exchanges.

Crossbar switches use switching matrices made from a two-dimensional array of contacts arranged in an x-y format. These switching matrices are operated by a series of horizontal bars arranged over the contacts.

Each such select bar can be rocked up or down by electromagnets to provide access to two levels of the matrix. A second set of vertical hold bars is set at right angles to the first hence the name, "crossbar" and also operated by electromagnets.

The select bars carry spring-loaded wire fingers that enable the hold bars to operate the contacts beneath the bars. When the select and then the hold electromagnets operate in sequence to move the bars, they trap one of the spring fingers to close the contacts beneath the point where two bars cross.

This then makes the connection through the switch as part of setting up a calling path through the exchange. Once connected, the select magnet is then released so it can use its other fingers for other connections, while the hold magnet remains energized for the duration of the call to maintain the connection.

However, the Bell System Type B crossbar switch of the s was made in the largest quantity. The majority were point switches, with twenty verticals and ten levels of three wires, Each select bar carries ten fingers so that any of the ten circuits assigned to the ten verticals can connect to either of two levels.

Five select bars, each able to rotate up or down, mean a choice of ten links to the next stage of switching. Each crosspoint in this particular model connected six wires.

The vertical off-normal contacts next to the hold magnets are lined up along the bottom of the switch. They perform logic and memory functions, and the hold bar keeps them in the active position as long as the connection is up.

The horizontal off-normals on the sides of the switch are activated by the horizontal bars when the butterfly magnets rotate them. This only happens while the connection is being set up, since the butterflies are only energized then.

The majority of Bell System switches were made to connect three wires including the tip and ring of a balanced pair circuit and a sleeve lead for control.

Many connected six wires, either for two distinct circuits or for a four wire circuit or other complex connection. The Bell System Type C miniature crossbar of the s was similar, but the fingers projected forward from the back and the select bars held paddles to move them.

The majority of type C had twelve levels; these were the less common ten level ones. The ITT Pentaconta Multiswitch of the same era had usually 22 verticals, 26 levels, and six to twelve wires.

Ericsson crossbar switches sometimes had only five verticals. For instrumentation use, James Cunningham, Son and Company [3] made high-speed, very-long-life crossbar switches [4] with physically small mechanical parts which permitted faster operation than telephone-type crossbar switches.

Many of their switches had the mechanical Boolean AND function of telephony crossbar switches, but other models had individual relays one coil per crosspoint in matrix arrays, connecting the relay contacts to [x] and [y] buses.

These latter types were equivalent to separate relays; there was no logical AND function built in. Cunningham crossbar switches had precious-metal contacts capable of handling millivolt signals.

Early crossbar exchanges were divided into an originating side and a terminating side, while the later and prominent Canadian and US SP1 switch and 5XB switch were not.

The sender then recorded the dialed digits and passed them to the originating marker, which selected an outgoing trunk and operated the various crossbar switch stages to connect the calling user to it.

The originating marker then passed the trunk call completion requirements type of pulsing, resistance of the trunk, etc. The sender then relayed this information to a terminating sender which could be on either the same or a different exchange.

The crossbar switch itself was simple: The design criteria specified only two hours of downtime for service every forty years, which was a large improvement over earlier electromechanical systems.

The exchange design concept lent itself to incremental upgrades, as the control elements could be replaced separately from the call switching elements.

The minimum size of a crossbar exchange was comparatively large, but in city areas with a large installed line capacity the whole exchange occupied less space than other exchange technologies of equivalent capacity.

For this reason they were also typically the first switches to be replaced with digital systems, which were even smaller and more reliable.

Two principles of crossbar switching existed. An early method was based on the selector principle, and used the switches as functional replacement for Strowger or stepping switches.

Control was distributed to the switches themselves. Call establishment progressed through the exchange stage by stage, as successive digits were dialed.

With the selector principle, each switch could only handle its portion of one call at a time. Each moving contact of the array was multipled [ clarification needed ] to corresponding crosspoints on other switches to a selector in the next bank of switches.

Distributed control meant there was no common point of failure, but also meant that the setup stage lasted for the ten seconds or so the caller took to dial the required number.

In control occupancy terms this comparatively long interval degrades the traffic capacity of a switch. Starting with the 1XB switch , the later and more common method was based on the link principle, and used the switches as crosspoints.

Each moving contact was multipled to the other contacts on the same level by simpler banjo wires, to a link on one of the inputs of a switch in the next stage.

The switch could handle its portion of as many calls as it had levels or verticals. The link principle was more efficient, but required a more complex control system to find idle links through the switching fabric.

This meant common control , as described above: A marker-controlled crossbar system had in the marker a highly vulnerable central control; this was invariably protected by having duplicate markers.

The great advantage was that the control occupancy on the switches was of the order of one second or less, representing the operate and release lags of the X-then-Y armatures of the switches.

The only downside of common control was the need to provide digit recorders enough to deal with the greatest forecast originating traffic level on the exchange.

The Plessey TXK 1 or design used an intermediate form, in which a clear path was marked through the switching fabric by distributed logic, and then closed through all at once.

Crossbar exchanges remain in revenue service only in a few telephone networks. Preserved installations are maintained in museums , such as the Museum of Communications in Seattle, Washington, and the Science Museum in London.

Semiconductor implementations of crossbar switches typically consist of a set of input amplifiers or retimers connected to a series of metalizations or bars within a semiconductor device.

A similar set of metalizations or bars are connected to output amplifiers or retimers. Bird put down after getting stuck to painted crossbar.
