Digital Switching System

A Digital Switching System is a modern telecommunications technology used to manage the routing of digital signals between different communication networks or devices. Unlike traditional analog switching systems, which use continuous electrical signals, digital switching systems rely on binary data (1s and 0s) to represent information. These systems are designed to handle a variety of digital communications, including voice, data, and video, ensuring reliable, efficient, and high-quality communication for businesses, telecom providers, and large enterprises. The digital switching system acts as the backbone for modern telecommunications, enabling the seamless transmission of information over long distances or within a local area network (LAN).

The C-DOT 256 Port RAX (Rural Automatic Exchange) is a Stored Program Controlled (SPC) Digital Switching System with a capacity of 256 terminations, which include subscriber lines, trunks & service circuits. It can act as a terminal exchange, Integrated Local-cum-Transit (ILT) exchange or Purely Transit Exchange. This could be placed in secondary switching area as a tertiary centre providing connectivity amongst a number of RAXs, TAXs and manual trunk positions, in addition to local-subscribers. It employs a completely non-blocking 4 wire PCM switching network, which forms the basis for high capacity, total system availability and high traffic handling capacity.

SILENT FEATURES OF THE SYSTEM:1. It is a digital switching with single T stage switch. A maximum of 2048PCM s can be connected.2. It supports both analog and digital subscribers.3. It supports all the existing signalling systems, like decadic, MF (R2), CASand also CCITT#7 signalling system.4. It provides telephony, ISDN, Data communication, cellular radio, and other value added services.5. The system has automatic recovery feature. When a serious fault occurs ina control unit, it gives a message to SMM. The SMM puts this unit out of service,loads the software of this unit in a back up unit and brings it into service.Diagnostic programmes are run on the faulty unit and the diagnostics is printed ona terminal.6. It has a double remoting facility.Subscribers access unit can be placed at are mote place and connected to the main exchange through PCM links. Further,line concentrators can also be placed at a remote location and connected to theCSNL or CSND through PCMs.7. Various units of OCB 283 system are connected over token rings. This enables fast exchange of information and avoids complicated links and wiring between various units.8. The charge accounts of subscribers are automatically saved in the disc, once in a day. This avoids loss of revenue in case of battery failure.9. The traffic handling capacity of the system is huge.10. The exchange can be managed either locally or from an NMC through 64kb/s link.11. All the control units are implemented on the same type of hardware. This is called a station.12. The system is made up of only 35 types of cards. This excludes the cards required for CSN. Due to this, the number of spare cards to be kept for maintenance, are drastically reduced.13. The system has modular structure. The expansion can be very easily carried out by adding necessary hardware and software.14. The SMMs are duplicated with one active other standby. In case of faults,switch over takes place automatically.15. The hard disc is very small in size,compact and maintenance free. It has a very huge memory capacity of 1.2 Giga bytes.16. The space requirement is very small.17. There is no fixed or rigid rack and suite configuration in the system.
