Technical Information

Main characteristics

The Alcatel 1000 S12 switching system (formerly known as ‘System 12’ or ITT 1240) is also one of the most popular in the world including at one point in time 140 million Alcatel S12 lines in more than 100 countries worldwide.

The Alcatel S12 is an optimized cost-effective, multi-purpose voice switch covering the entire exchange application range of local, toll, combined local & toll, tandem and international exchanges.

The Alcatel S12 Media Gateway Controller(MGC) was later designed to meet the Next generation network (NGN) requirements and employing this product together with the Alcatel 7510 Media Gateway (MG), service providers can handle both TDM and voice over packet (VoP) traffic in an NGN architecture.

Capacity

The S12 software has five major sub-systems: operating system, telephonic support, call handling, maintenance and administration.

Modular Architecture

The Alcatel S12 system’s distributed control architecture incorporates modular hardware components which conform to a defined interface with the DSN (Digital Switching Network).

The modular design means that the exchange architecture, and top level software doesn’t need to be adapted when updating smaller features such as components, microprocessors or custom VSLI circuits.

Implementation

The number of different printed circuit boards types is only 29 for a typical exchange. The number of different rack types from which a typical exchange is built is 4. For a typical 10,000 line exchange the Alcatel 1000 S12 9 racks and 9KW of power.

Remote Subscriber Unit
