16 SERIAL PORT CONFIGURATION
This chapter provides an overview of the serial port and describes the tasks involved in configuring the
serial port through the Inalp SmartWare. For detailed information on syntax and usage guidelines for
the commands listed under Configuration Tasks, refer to the Chapter 23, "Port Serial Mode" of the
SmartWare
Command Reference Guide
.

16.1 Introduction
The SmartNode 2000 series device supports both the V.35 and X.21 standard for synchronous serial
interfaces with speeds up to 2 Mbit/s. The V.35 standard is recommended for speeds up to 48 kbps,
although in practice it is used successfully at 4 Mbit/s. The X.21 standard is recommended for data
interfaces transmitting at rates up to 2 Mbit/s 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 SmartNode
Hardware Installation Guide
for
specific information regarding the connector pinout and the selection of cables to connect with 3
rd
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 network. The advantage of this technique is that it provides more
flexibility and more efficient use of bandwidth.
