E1OB is a digital switching system, which supports only analogue voice communication. It is a telephone switching system based on electronic components and techniques. Two main operating principles are carried over from the PLATON system. One use of PCM digital techniques and Separation of switching functions from operation and maintenance functions.

This switching system can be used to transmit a variety of signals like telephone, telegraph and data. This exchange can accommodate any required combination of subscriber lines and trunk circuits.

CSN “DIGITAL SUBSCRIBER CENTER” equipment is a subscriber connecting entity of OCB 283 Telephone exchange, designed to provide telecom service to analogue and digital subscribers. Its design enables it to fit in the existing E-10B networks or OCB-283 to a time based system using the CCITT No.7 type of semaphore signalling. It is designed for the ISDN application also.

C-DOT MAX-XL is a universal digital switch can be configured for different applications as local, transit or integrated and transit switch. It has high traffic / load handling capacity up to 8,00,000 BHCA with termination capacity of 384 to 40,000 lines as local Exchange or 15,000 trunks as Trunk Automatic Exchange. C-DOT MAX-XL is a modular and flexible digital system which provides economical means of serving rural and urban environments.

Base Trans-Receiver Station (BTS) “BTS A 9100” is radio frequency mobile communication product based on GSM technology. It is a set of equipments that facilitates wireless communication between user equipment (UE) and a network. A BTS in general consists of Trans-receiver module antenna network Combiner, Controller card (SUMA) & Alarm Extension System (XIBM). It is a self contained unit for transmitting / receiving signal for mobile communication.
