DSX-1 PLUG-ON BOARD OVERVIEW
The DSX-1 plug-on board is one of the plug-on options
available for use with the ADTRAN TSU 100/600. The
DSX-1 plug-on board provides a single DSX-1 interface
that can be used to provide access to a PBX, router, or
other equipment that uses 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 DSX-1 plug-on
board is selectable.

Introduction
When plugged onto any option card other than the drop
and insert (D&I) or DSX-1 option modules, the DSX-1
plug-on board operates exactly like the DSX-1 passthru
option module. The DSX-1 plug-on board can also be
installed on option modules in slots 1 through 5 of the
TSU 600 and used as a data port for applications not
requiring robbed-bit signaling. When plugged onto a
drop & insert option module, the DSX-1 plug-on board
can be used as a PBX port for the drop & insert T1. In
this configuration, robbed bit-signaling can be enabled
or disabled from a front-panel menu option.
FUNCTIONAL DESCRIPTION
The DSX-1 plug-on board operates as a plug-on with any
TSU option module. The DSX-1 plug-on board is
configured from the front panel of the TSU 100/600 or
by an external personal computer (PC) program. The
