(Broadband Integrated Services Digital Network Switching Platform)
C-DOT has designed an ATM (Asynchronous Transfer Mode) technology based broadband switching system. The solution consists of an ATM switch for use in the backbone network and an NIU (Network Interface Unit) for use in the access network. The ATM switch provides the ATM interfaces for connecting the ATM devices to it and offers voice and data services to them. The NIU provides the non-ATM interfaces for connecting the non-ATM devices over the ATM backbone. The switching capacity of an ATM switch is 5 Gbps and the solution is scalable and fault-tolerant.
