Introduction

This chapter describes the ports on the Option 11C system. Serial Data
Interface (SDI) ports are used to connect devices such as terminals and
modems to the Option 11C. The two types of SDI ports supported are:

•

Data Terminal Equipment (DTE); typically a TTY or computer

•

Data Communication Equipment (DCE); typically a modem
