The ADTRAN OC-3c/STM 1 Cell Switch Module installs into a single CSM slot in the Total Access DSLAM chassis and interfaces to the network via SC connectors that attach to the circuit board through the faceplate. A dual configuration is optional for redundant capability, with the system being fully functional with only a single MUX installed.
Standard traffic types such as UBR, CBR, rt-VBR, and nrt-VBR, are supported for data and Voice over DSL (VoDSL) services. The CSM employs traffic prioritizing and policing on a per VC (Virtual Circuit) basis to ensure proper delivery of customer data.
Efficient data delivery is maximized through early packet discard and partial packet discard. Substantial buffers are also utilized to optimize data throughput.
The Total Access OC-3c/STM 1 CSM supports both local and remote management. Operation, Administration, Maintenance, and Provisioning (OAM&P) tasks can be performed through the OS interface on the SCU. Remote management via Telnet, Total Access Element Management System (EMS), TL1, and SNMP is supported through the SCU. Reporting and managing of the QoS is also supported. The OC-3c//STM 1 CSM also exercises synchronized Performance Monitoring (PM) and provisioning between active and standby units.
