Product Architecture
The port adapters support new algorithms for managing data. On the transmit side, they can either
pull packets out of memory (Pull Model) or wait until the main processor pushes the packets to the
port adapter (Push Model) for transmission. The Push Model—the most efficient algorithm—is
activated only when the port adapters are installed on a Cisco 7204VXR, Cisco 7206VXR, Cisco
7201, or Cisco 7301 platform with the NPE-400, NPE-G1, and NPE-G2 network processing
engines. Additionally, they are two-in-one because they can be software-selectable to operate in
either T3 or E3 modes.
Chassis and Processors
The Cisco 1- and 2-Port Enhanced Capability Clear Channel Port Adapters are supported on the
