High network availability is supported with the by equipping a Tellabs 1000 MSAP system with two (2) OC12c-XCVR plug-in cards. This configuration assures system, card level and per port level redundancy.
As a general purpose interterminal transceiver, the OC12c-XCVR carries both TDM and ATM traffic: TDM traffic is converted to ATM cells. 50 Mbps are reserved for the TDM backplane. The OC12c-XCVR contains Tellabs’ next generation ASIC, the Pathfinder, which is a key differentiator and technology enabler providing access to the ATM cell bus. The Pathfinder functions as an “ATM switch on a chip” providing ATM switching, QoS, concentrator capabilities, and conversion of TDM traffic to ATM and back to TDM.
