IR-G.703/CO Interface

Module

C.1 Introduction

IR-G.703/CO is an interface module for RAD modems that converts G.703 64

kbps codirectional signals to TTL levels. The converted data is sent over the

modem link using the modem modulation technique and converted back at the

other end into G.703 64 kbps codirectional signals, or into any other digital

interface signal possible. IR-G.703/CO is available with two types of physical

connections: a terminal block or an RJ-45 (see Table C-1 for the RJ-45 connector

pinout).

Figure C-1 illustrates the panel of the IR-G.703/CO interface module.
