Introduction; Serial Port Configuration Task List - Patton electronics SmartNode Series Software Configuration Manual

14 • Serial port configuration

Introduction

This chapter provides an overview of the serial port and describes the tasks involved in configuring the serial
port through the Patton SmartWare, it includes the following sections:
• Serial port configuration task List
• Configuration tasks
• Examples
The SmartNode 2000 series device supports both the V.35 and X.21 standard for synchronous serial interfaces
with speeds up to 2 Mbps. The V.35 standard is recommended for speeds up to 48 kbps, although in practice
it is used successfully at 4 Mbps. The X.21 standard is recommended for data interfaces transmitting at rates
up to 2 Mbps and is used primarily in Europe and Japan.
The synchronous serial interface supports full-duplex operation and allows interconnection to various serial network
interface cards or equipment. Refer to the getting started guide included with your SmartNode device for specific
information regarding the connector pinout and the selection of cables to connect with 3rd party equipment.
The SmartNode 2000 series device supports the Frame Relay protocol on the synchronous serial interface.
Frame Relay is an example of a packet-switched technology. Packet-switched networks enable end stations to
dynamically share the network medium and the available bandwidth. Variable-length packets are used for more
efficient and flexible transfers. These packets then are switched between the various network segments until the
destination is reached. Statistical multiplexing techniques control network access in a packet-switched net-
work. The advantage of this technique is that it provides more flexibility and more efficient use of bandwidth.
