Introduction

Chapter 1

Introduction

The Motorola UTA220 terminal adapter connects existing Data Terminal Equipment (DTE) to the Integrated Services Digital Network (ISDN). The UTA220 uses the ISDN Basic Rate Interface which consists of two bearer (B) channels for data and one delta (D) channel for signaling.

The UTA220 has two DTE port connectors. In addition, the UTA220 can be ordered with two additional DTE port connectors for EIA-232 asynchronous use or EIA-366 dialing. Each DTE has access to the 56 kbps/64 kbps ISDN B channels. The UTA220 functions similarly to two standard modems in this mode.
