SIC-1AM/SIC-2AM
Introduction 1/2-port analog modem interface card (SIC-1AM/SIC-2AM) integrates the
functions of asynchronous interface and external modem, that is, allowing 1/2
channel(s) of remote modem subscribers to directly access the Router. They
support:
■ Data rate of 56 kbps.
■ Accessing and handling analog signals and transmitting the processed data to
the Router host through the serial interface bus. And also, processing the data
received from the host and then transmitting them to the PSTN via the
telephone port.
