Alcatel This lists Alcatel switches before the merger with Lucent Technologies. 1000 E10 / S12 (during the 1990s the E10 and S12 systems were converted into a single product line) E10 versions: E10A (E10N3)- Original switch introduced in 1972 one of the earliest deployments of TDM switching in the world. E10B (E10N1)- Major revision in the 1980s which eventually saw ISDN capabilities. Common in France, Ireland, China, India and elsewhere. E10B3 - major revision in the 1990s. Common in France & Ireland OCB-283 - Another name for more modern versions of E10B and often the name used in India to distinguish it from older versions. E10-MT formerly Thomson MT-25 found mostly in France, and MT20 too. E10-Five E10B adapted for the North American environment as a class-5 switch. E10S satellite switching unit. E10-MSC mobile switching center for GSM and other protocols. 1000 (MM) E10 - Evolved switch for multimedia / broadband and IP network environments. Provides POTS/ISDN and next generation services. S12 - Formerly known as "System 12" or the ITT 1240 or acquired by Alcatel when it purchased ITT's assets in Europe. This is a very widely deployed switching system found in Italy, Germany, Belgium, Australia and many other countries around the world. There are a large number of versions of this type of switch ranging from local, to transit to international gateway to mobile switching centers. The line was converted with the E10 family of exchanges. OmniPCX Office OmniPCX Enterprise

Hasler List of the mainly electro mechanical switching systems from Hasler AG Bern, which were used in public telephone network in Switzerland for many decades. Hasler AG finally merged into Ascom in 1987.
HS 25 (modified from the Ericsson OL-100 system with double relays and 25-point selector (Ericsson license), mainly used for small villages and towns in the counties) HS 31 (new developed register system, introduced in 1931, based on a new flat type relay and a 100-point two-motion selector, suitable for small and large exchanges) HS 52 (new developed register system, introduced in 1953, based on a new 120-point selector, which was in fact a 4 x 30-point uniselector with 2 x 4 brushes offset by 180°, no zero position) HS 52 A (new variant of HS 52 from 1973 with an almost full-electronic register evaluation unit called 'Umrechner', not processor based but centralized programmable by diode matrices) HS 52 B (Processor controlled multiregister system with identifier, but the relay and selector based coupling stage was maintained from the original HS 52 system) HS 68 (prototype of a semi-electronic switching system, based on adhesive reed-relays in the coupling stage. One sample system built but not pursued because of the arising PTT IFS-project) AXE-10 (digital switching system from Ericsson, initially built and adapted for the Swiss market by Ascom Hasler under Ericsson license)
The last HS 52 A and B exchanges were in operation until the end of 1997. The personnel-intensive electro mechanical systems were shut down prematurely then, due to the imminent opening of the telecoms market in Switzerland. The last AXE-10 local subscriber were migrated to VoIP in June 2020.

ITEC
EMS-1 (The ITEC Electronic Modular Switch is an electronic direct control switching system. The modules are combined to form a complete switch or any of the modules can be added to your present Step-by-Step Systems.) EMS-2 (The EMS-2 RURAL SWITCH is a stored program control analog switch designed to be cost-effective in small exchanges. The modular design with connectorized cabling permits fast initial installation and growth. The system requires minimum maintenance and is particularly suitable for unattended exchanges. The EMS-2 distributed control design prevents total switch failure which could isolate a remote community.) IDS (Integrated Digital System)
