SCA
IP178C/IP178CH
performs SCA on each port and shows the test result on LED pins whenever pin SCA
is pulled high. The LED display is independent of LED_SEL pins. The following table shows the LED
behavior of a port performing SCA.

Bandwidth control
IP178C/IP178CH
provides the bandwidth control mechanism to manage or control the data rate on a
limited bandwidth network. By controlling the ingress data rate and the egress data rate, it provides a
bandwidth management solution for local area networks and also provides quick and easy allocation of
uplink or downlink speeds to meet and guarantee a wide range of customer bandwidth requirements.
IP178C/IP178CH
provides the easiest way to allocate bandwidth for each port, which defined in MII
registers 31.26 ~ 31.29 or EEPROM registers 116 ~ 123. The ingress/egress data rate control range is
from 128 kbps to 8 Mbps for each port.
