The driver ICs have maximum current ratings higher than the continuous currents we specify for these carrier boards, but the actual current you can deliver depends on how well you can keep the IC cool. The carrier’s printed circuit board is designed to draw heat out of the IC, but to su...

Problem to be solved: to provide a carrier coated copper foil with a good suppression of generation of copper residues exceeding the circuit width when the predetermined circuit is formed on the ultrathin copper layer after the carrier is stripped and removed by adhering to the resin substrate. ...
This figure shows the wiring of an AC Delta power shelf. Four-wire AC Delta 3-phase power is wired into the AC Delta power shelf at a terminal block (TB1). The 3-phase power is then routed through the shelf circuit Cisco CRS Carrier Routing System Multishelf System ...
function exists between the two data planes. The data-plane interworking function is performed by an integrated circuit called an Ethernet mapper, a network-processing unit (NPU), or a customized field-programmable gate array (FPGA). In the SONET/SDH example, an integrated Ethernet-over-SONET/SD...
