2.2 Router 1-Port Serial SIC

2.2.1 Introduction

1-port multiprotocol synchronous/asynchronous serial interface card (Router 1-Port Serial SIC) supports both synchronous and asynchronous operating modes. It supports:

z z

Transmission/Receiving and handling of synchronous and asynchronous serial data streams;

Different operating modes, such as V.24/V.35 and DTE/DCE, depending on the actual applications;

Automatic external cable type detection without the need of manual configuration; Local loopback and remote loopback, facilitating fault test and location.

I. Synchronous and asynchronous

In different operating modes, a synchronous/asynchronous serial interface supports different signal standards and baud rates and the maximum transmission distance of the signals is related to the baud rate setting. For the relationships between cable type, baud rate setting and signal transmission distance, see the following table.
