The E10 began life with considerable success in the marketplace between with more than one million lines per year in service , by building and progressing its product development whilst retaining the same basic architecture. Image Source: Amazon. Unlike other conventional systems at the time, the E10 was able to take its input signals in the form of a train of pulses. The conversion of the analog signals which represent speech to the pulse code modulated PCM digital form takes place in the local switch units, each of which serve around subscribers.

At the other end of the line, the digital signals are turned back into analog wave form by remote switches and then transmitted on to the receiving subscriber. The use of microelectronics made it much more efficient and lowered the cost of transmitting signals in this way. As the equipment only needed to recognise the presence or absence of the bits to be able to be able to reconstruct the original speech wave-form, the quality and loudness of the speech signals were made independent of the distance between the calling and called person.

Having digital PCM links between all local switched and the main E10 unit also allowed for setting up, ringing, and clearing down all telephone calls progressing through the local units serving the subscribers. Being able to control a complete telephone area with a single computer installation made it far easier for providers to provide customers with new facilities.

The system was introduced along with the Alcatel and S12 products, as a complete family of SDH and SONET products including line equipment, add drop multiplexers and cross connects as well as optical fiber access products. There is continued high-demand for Alcatel E10 parts for networks which still use the technologies to this day.

E10B Digital Switching System

This list of telephone switches is a compilation of telephone switches used in the public switched telephone network PSTN or in large enterprises. This lists Alcatel switches before the merger with Lucent Technologies. Automatic Electric started producing electromechanical switching systems in the 19th century. The McBerty design used an early " wire spring relay " and welded piano wire interconnections rather than complex wire multiples.
