1000 E10 / S12 (during the 1990s the E10 and S12 systems were converged 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.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 for satellite communications.E10-MSC mobile switching centre 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 centres. The line was converged with the E10 family of exchanges.OmniPCX OfficeOmniPCX EnterpriseMT-20MT-25MT-3532A4232A4435E97370A370B375A375B385A385BC1-EAXCXP5CXP5AEAX1EAX2EAX3ESU 3072 LineFW1GTD-3 EAX (Toll switch, NOT CCS7 capable)GTD-5 EAX (Class 5 switch, many in use today, was the primary switch in former GTE exchanges.

CX30 (30 line)CX60 (60 line)CX100 (100 line)CX200 ("broadspan" up to 200 lines)CX1000 (large CX expandable to 10,000 lines)MCX A version of the CX product line designed by F.R. McBerty after leaving Western Electric/Bell Labs and becoming President of North Electric.The McBerty design used an early "wire spring relay" and welded piano wire interconnections rather than complex wire multiples. The system never achieved the reputation of the CX product due to problems with poor contact pressure in the interconnection relays. Despite its much lower cost of production and installation, the level of maintenance required to keep these systems on good order doomed this variation of the CX design.

Ericsson purchased North Electric in the early 1950s and brought this Swedish design to North where it was reworked to conform to U.S. telecommunications requirements.
NX1D (Final production version)NX1E (NX-1D with OMNI Processor for line/directory, trunk and number-group translation services)The NX-1E was not a SPC switch, rather it was a conventional path controlled switching matrix with electronic processors (computers) replacing the control, route selection and translation (directory number to line ID) functions.

Ericsson in the early 1960s. The "United" version of NX-2A replaced the intercabling connection blocks with wire wrap connections so that switches could be installed or expanded without having custom cable harnesses provided by North Electric.Switcher Family (NX-2A pre-installed in a trailer for rapid installation or portable/emergency use)TSW Basic Unit with growth to ~360 linesTSW2 Expanded unit with growth to ~1200 linesTSW3 Jumbo unit with growth to system recommended maximumsTSD (toll switch)AN/TTC-20 568 Line Military Fixed Switch (Used by US Air Force - only one was known in existence at Sembach AB, Germany) (retired)AN/TTC-30 568 Line Military Tactical Mobile Switch (Used by US Army and Air Force) (retired)Application Server 5300 (AS5300)Business Communications Manager (BCM)BCM50BCM200BCM400BCM450Nortel Norstar Key Systems308616824 ModularNorstar CICS (Compact Integrated Communication System)Norstar MICS (Modular Integrated Communication System)Nortel Meridian 1 PBXOption 11/11E/11COption 21/21COption 51/51COption 61/61COption 81/81CCommunication Servers (CS Systems)CS1000 (22,500 lines 3200 trunks TDM and VoIP)CS1500 (48,000 lines 8,400 trunks TDM and VoIP)CS2000 CompactCS2000 (180,000 lines 200,000 trunks TDM and VoIP)CS2100 (230,000 ports, 125,000 IP phones, 150,000 analog telephones, 125,000 digital telephones, 200,000 IP trunks, 50,025 digital trunks, 32,000 analog trunks, 200,000 SS7 trunks, 4,093 H.323 gateways, 112,000 nodes per host, 99,999 ACD agents)Digital Multiplex System (DMS)DMS-10 Carrier Class Switching System (320 ISDN PRI links or more than 20,000 lines) (First "production" class 5 digital switch installed in the North American public telephone network)DMS-10 RLCM (640 line remote)DMS-10 RSLE (520 line remote)DMS-10 RSLM (640 line remote)DMS-10S (super small DMS-10 for very small exchanges, less than 640 lines)DMS-10M (prepackaged DMS-10, a Community Dial Office in a pre-packaged container/"box")DMS-100 FAMILY of Digital ExchangesDMS-100 (large local digital Class 5) (also known as an SL-100 when used as CPE (Customer Provided Equipment or PBX service)DMS-100/200 (local/toll digital more than 135,000 lines)DMS-200 (toll digital)DMS-250 (Equal Access Carrier Switch-digital)DMS-300 (International Gateway Switch-digital)DMS-300/250 (combination Carrier/International Gateway 70,000 to 100,000 trunks)DMS-500 (Local/Toll + CLEC Switch)DMS-Global Services PlatformDMS-MTX (Cellular MTSO)Stored Program (SP) (Electronic Stored Program Control using mini-bar switches)SP1 2-Wire (Local)The SP1 processor was constructed using Small Scale Integration (SSI) Diode Transistor (DTL) Logic. Two types of memory was used. Processor read/write scratch memory (called CALL STORE) was implemented using a magnetic core variant called Ferrite Sheet. Program and Data Store (used to store Software and infrequently changed data) was implemented using a technology called piggy back twistor - in modern parlance a write once, read many times non-volatile memory system). As was the case with the #1ESS systems, processors and memory were duplicated with automatic comparison of processing results and automatic recovery in the event that a mismatch was discovered. It did not however support the complex recovery mechanism provided in the #1ESS where a processor from one half of the complex could be connected to a mix of memory (both call store and program store) modules from both halves of the complex in order to achieve a working combination. Processor diagnostics would generally narrow a problem down to a board or three. Connection was made via a crossbar switch.A SP1 2-wire variant was also available that provided Centrex services.A version of the SP-1 ESS that could provide both 2 & 4 wire services was also built. The first instance was installed in Vegreville Alberta in 1976 or 1977.SP1 4-Wire (Toll)The first example of this switch was installed for Bell Canada, in Thunder Bay, Ontario in late 1973. It provided toll services for North Western Ontario and CAMA (Centralized Message Accounting) for the City of Thunder Bay. The City of Thunder Bay which operated its own Telephone Company installed a number of 2W SP1s.SP1E (used NT40 processor which was later the first processor system for the DMS-100 Family of switches)NE-1ESS (Northern Electric version of Western Electric) #1ESS {licensee}Bell Canada operated NE-1ESS 2 wire switches (some of which also provided Centrex services) in Toronto, Ottawa and Montreal. A 4W NE-1ESS was installed in Thunder Bay to provide telephone switching services (SAGE and AUTOVON)for USA and Canadian bases in that part of North America. The #1ESS was implemented using discrete diode transistor logic. A typical circuit board would implement a single 4 input "NAND" gate. Of the myriad of cards in the system - many were dedicated diagnostic gates. The diagnostic software had a very high (95% +) success rate identifying a single failing card. The success rate dropped quickly thereafter. Drifting Voltage Regulator cards caused a lot of angst.NE-4A (Northern Electric version of Western Electric) 4A toll {licensee})NE-5XB (Northern Electric version of Western Electric) #5Xbar {licensee})SA1 (Small Northern designed crossbar CDO)SA2 (Small Northern designed crossbar CDO)SF1 (Small Northern designed crossbar CDO)NorstarElif IElif I IDRX-4D60D70Discovery I PBXDiscovery II PBXDiscovery III PBXDiscovery 8000 PBXD10 D60 D70 KB270URUR NBUR49URVBUVPRX/APRX/Dis3000 TDM PBXSIP@Net Server Software PBX ( owned by NEC )CBX (Versions 5,6,7000)CBXII (Versions VS,S,M,L 8000-8004, VL 9000-9004)9751 CBX (IBM co-design) 9004/9005 versions (Models 10,20,40,50 and multinode 70)9751-9006i (Version 1-6; Also called Models 30 and 80); Sold also as Siemens Hicom/HCM300Redwood (limited key system)Proton-SSSDKTS 20DKTS 30TRANSipSLICEHDXIGX-AIGX-MTIGX-NMDX 10KMDX 384 modular exchange "stackable" to 384 lines/trunksEltex II (Telex)Eltex V (Telex)S-1240SDX-100SDX-200SDX-RBTDX-1TDX-1BTDX-10SD50 PBXSD192MX PBXSD232 PBXSaturn I PBXSaturn II PBXSaturn IIE PBXSaturn III PBXHicom 100Hicom 150/150EHicom 200 (Also sold as the ROLM 9200 CBX)Hicom 300 (Also sold as the ROLM 9751-9006i CBX)HiPath 3000HiPath 4000HiPath 5000HiPath 8000OpenScape SIPNo. 16 Step-by-StepNo. 17 Step-by-StepNo. 51 Step-by-StepEDX-PEMD55EMD56EMD57ESK - CP24ESK - CP44ESK - CP44AESK 10000 EEWSDRemote Switch Unit RSU-DE3Remote Switch Unit RSU-DE4Remote Switch Unit RSU-DE5RCUB-800CDCO-CS (Formerly Stromberg Carlson DCO) - Sold to Genband in 2006HiQ8000SPX2000 (Formerly Equitel)GSX9000GSX4000PSX6000EMS 12000Topcom 601Topcom 200Hicom 300DCO 21DCO 80DCO 200DCO 360Century DCO6000DCO Remote Line Switch 1000 (RLS 1000)DCO Remote Line Switch 4000 (RLS 4000)RLS 450DCO-SEDTMESC-1 "Crossreed" electronic exchangeESC-3MS30SC#5 (#5 Crossbar licensed from Northern Electric (Canada) for US sales/distribution)Motorswitch - Siemens (Germany)XY (Stromberg version of Ericsson "flat motion" switch operated in horizontal planes)The DCO family starts as generic DCO
