ATM
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.
• Duplex Redundancy of Network Health Monitoring System (NHMS) • Network Time-of-day Synchronization • Physical Layer Protection Switching • ATM Layer Protection Switching • Flash Programming from Local Management System • SNMP based Network Management
The solution is compliant to ITU-T, ATM Forum and IETF standards.
