A dual configuration is optionalfor redundant capability, with the systembeing fully functional with only a singleMUX installed.Standard traffic types such as UBR, CBR,rt-VBR, and nrt-VBR, are supported for dataand Voice over DSL (VoDSL) services. TheCSM employs traffic prioritizing and policingon a per VC (Virtual Circuit) basis to ensureproper delivery of customer data.Efficient data delivery is maximizedthrough early packet discard and partialpacket discard. Substantial buffers are alsoutilized to optimize data throughput.The Total Access OC-3c/STM 1 CSMsupports both local and remote management.Operation, Administration, Maintenance,and Provisioning (OAM&P) tasks can beperformed through the OS interface on theSCU. Remote management via Telnet, TotalAccess Element Management System (EMS),TL1, and SNMP is supported through theSCU. Reporting and managing of the QoS isalso supported. The OC-3c//STM 1 CSM alsoexercises synchronized PerformanceMonitoring (PM) and provisioning betweenactive and standby units.Global Solutions
