T7289A DS1 Line Interface
5
Lucent Technologies Inc.
Overview
The T7289A device is a fully integrated DS1 line interface that requires only two line-interface transformers and
three input termination resistors to provide a bidirectional line interface between a DS1 cross connect (DSX) and
terminal equipment. A typical application diagram is shown in Figure 3. This device is specified for use with
22-gauge, plastic-insulated ABAM cable, as well as other cable types. The circuit is divided into three main blocks:
transmit converter, receive converter, and logic. The transmit and receive converters process information signals
through the device in the transmit and receive directions, respectively; the logic is the control and status interface
for the device.
Note: Lucent 2745 family pulse transformers for through-hole mounting or Lucent 2758 family pulse transformers for surface mounting are
recommended.
