Exp	Project Details: The product consists of DS3 Line Interface cards – one for incoming traffic and second for outgoing traffic. The DS3 lines carry ATM cells in which IP and Non IP traffic are embedded. The DS3 Line Interface Unit terminates the DS3. In the receive direction the DS3 header is removed and the Header Error check is performed and the ATM cells are transmitted on the UTOPIA Bus. In the Transmit direction the DS3 framer frames the ATM cells received from the UTOPIA Bus. The T3 driver in the physical layer will ensure that the DS3 line is configured and the Performance monitoring and Alarms handling activities for the DS3 are in place.
