15 • Serial port configuration

Introduction

This chapter provides an overview of the serial port and describes the tasks involved in its configuration
through the SmartWare, it includes the following sections:
• Serial port configuration task list
• Configuration tasks
• Examples
The SmartNode 2300 device supports 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 suc-
cessfully 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 SmartWare for
specific information regarding the connector pinout and the selection of cables to connect with third-party
equipment.
The SmartNode 2300 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 dynami-
cally share the network medium and the available bandwidth. Variable-length packets are used for more effi-
cient and flexible transfers. These packets are then 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.
