CONCEPT 16 Telephone Concentrator

The STS Signals CONCEPT 16 Telephone Concentrator system has been designed to
meet the exacting requirements of Rail Administrations, especially when working in an
electrified environment.

Based on the well established CONCEPT 32 design, CONCEPT 16 shares many of the
same approved components, and is particularly valuable where smaller numbers of lines arerequired and space is at a premium.

The CONCEPT 16 system is used to control up to 16 remote telephones via a single control point from where each telephone may be called individually.

Applications include control of Signal Post Telephones (SPT’s) located at :

Signals
Point zones or ground frames
Level crossings
Station platforms

The CONCEPT 16 system may be powered by a local 50V dc supply or by our Compact UPS.
The system may be linked to any of the STS Signals range of keyboards or custom keypanel products.

The CONCEPT 16 is approved under Section 22 of the Telecommunications Act 1984.
A BABT approved version of the Telephone Interface (TIF) card and Auto Line card is
available, and these cards also allow connection to the PSTN.

Absolute security of speech is fundamental to the design. The called, calling or connected party is positively identified and only one line can be connected at any time. A third party cannot overhear a call, and call security is provided by relay inter-locking which is monitored by a microprocessor.

Inherent in the design is high reliability, simplicity of operation and ease of maintenance.
STS Signals’ concentrator systems have Network Rail Product Approval PA05/02830,
are CE approved and comply with Safety Standards EN 60950:2000, EMC Standards
EN50121-4:2000 and R&TTE Standard R&TTE(1999/5/EC).
