PASSTHRU OVER VIEW
The DSX-1 Passthru is one of the secondary interface
option modules available for use with the ADTRAN
TSU 100/600. The Passthru option card should be
selected to provide DSX-1 access for PBXs, or other
equipment, that use a DSX-1 interface. When used with
a PBX, this interface permits the combination of voice
and data in a single T1 stream. The allocation of the
amount of bandwidth for the Passthru is selectable.

Introduction
FUNCTIONAL DESCRIPTION
The Passthru is designed to fit in the option slot of the
TSU 100/600 and is subject to its operation and control.
The Passthru is configured from the front panel of the

program. The internal menus for its configuration are a
part of the Passthru card and are automatically installed
when the Passthru is plugged into the unit.
Features
The DSX-1 Passthru Option Module has the following
features:
• Operates using 1 to 24 DS0s
• Operates as a drop and pass-on or as a standard passon module

The Passthru rear panel includes a plastic plug over a
cutout for a V.35 connector. This allows a V.35 Nx56/64
interface plug-on card to be added to the Passthru card,
part number 1200053L1. The PORT X.1 identification
on the rear panel is linked to the port numbering
philosophy of the TSU 100/600 product family. The X

represents the slot number, and the .1 indicates the port
number. For the TSU 100/600 application, there is only
one option slot. Therefore the port designation for the
Passthru port is 1.1. If added, the Nx56/64 port
designation would be 1.2. These port numbers appear
in the front panel LCD menu displays.
