Abstract: – OCB 283 means Organ De CommandeB2 Version 8300 Microprocessor. It is the latest electronics digital ISDN type switching technology being imported in INDIA, OCB 283 is a digital switching system which supports a variety of communication needs like basic telephony, ISDN, interface to mobile communication, data communication etc, it is a Digital Switching System (DSS) with single ‘T’ stage switch. A maximum of 2048 PCM’s can be connected. It supports both analog and digital subscriber. Subscriber connected units (CSN) are so designed that they can be equipped with either analog subscriber or digital subscriber. Or both the cards for analog subscriber and digital are different, but can be equipped in any slot of the shelf. These provide facility to connect speech path from a subscriber’s loop or circuits from an external PCM’s and transfers these speech samples on to selected time slots called voice channels on a LR link (internal PCM). This provides access for Man Machine dialogues for the human operators to interact and command the working of exchange equipments.
