The Traffic-Shaping Carrier Access Module (TSCAM) provides enhanced traffic-shaping capabilities for Cisco port adapter modules (PAMs). Traffic shaping allows service providers to manage the bandwidth delivered to the customer premises, giving them the ability to efficiently plan and utilize the core network infrastructure. In addition, traffic shaping gives enterprise customers the ability to aggregate multiservice data from a wide range of interfaces and ensure that the data uplink stream is shaped to match the service-level agreement (SLA) from service providers.
