2.5 SIC-1AM/SIC-2AM
2.5.1 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:
z
Data rate of 56 kbps.
z
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.
