Chapter 1 Introduction
FXS+ QUAD AND DUAL VOICE OVERVIEW
The FXS Quad and FXS Dual Voice option modules can be
used with the ADTRAN TSU 100/120/600. The Quad FXS+
module provides four, 2-wire voice-grade interfaces serving
as the source of line-current and ringing voltage to a
telephone or station interface. The Dual FXS+ provides two,
2-wire voice-grade interfaces in either a plug-in or plug-on
module.
FXS+ Uses
The FXS+ may serve as the station-side of a foreign exchange
FXS/FXO application. It may be paired with another FXS+ to
provide a hotline or private line automatic ringdown (PLAR)
function to a remote location at the far end of the T-Span.
When the FXS+ is used in the tandem mode, it can be set to
accept phone service directly from a toll switch using E&M
signalling on the T-Span (e.g., 1-800 services, Megacom). It
may also be used to provide trunk services to a PBX from a
local switch. The FXS+ is intended for use in applications
where the 2-wire port wiring remains on premises.
The FXS+ option modules support Single Party and Universal
Voice Grade (UVG) Channel Unit Operation as specified by
TR-TSY-000008. The FXS+ module and a TSU 600/600e can
act as a remote terminal in a digital loop carrier application.
The FXS+ Dual plug-in option module also accepts the TSU
100/120/600 plug-on boards to provide up to four functional
ports per option slot used. Signalling and interfaces comply

PHYSICAL DESCRIPTION
The FXS+ is an option module which plugs into the option
slot in the rear of the TSU 100. The plug-on module is placed
on top of a plug-in module. See Figure 1-1.
Figure 1-1. FXS+ Quad & Dual Voice Option Modules
The rear panel of the dual plug-in module includes a plastic
plug over a cutout for additional connectors. This allows a
plug-on board to be added to the FXS+ dual plug-in module.
The 1200302L1 (FXS+ Dual) voice module can accept any
plug-on module except the 1200082L1#HS. The FXS+ dual
plug-on can be placed on top of any option module that
accepts plug-ons.
The PORT X.3 indication is linked to the port numbering
philosophy of the TSU 100 product family. The Xrepresents
the slot number, and the .3 indicates the port number. For the
TSU 100 application, there is only one option slot. Therefore
the port designations for the two plug-in FXS voice ports will
be 1.1 and 1.2. If added, the plug-on board port designation
would be 1.3 and 1.4. These port numbers will appear in the
front panel LCD menu displays. The remainder of the
manual will refer to port numbers as 1.1 or X.1 for
illustrative purposes.

INSTALLING THE FXS+ VOICE OPTION MODULE
Determine Revision Level of TSU 100/120/600
All TSU chassis support the FXS+ Quad/Dual Voice option
modules. TSU 100 units must have Software Revision L or
later, and the TSU 600 (1200076L1 and 1200076L2) must have
Software Revision F or later. To determine the revision level,
do the following:
If the card is to be installed in a TSU 100, 120 or 600 with an
earlier software revision, ADTRAN recommends that the
TSU first be upgraded to the most recent revision to ensure
proper operation with the FXS+.
For ease of replacement, power to the TSU 100/120/600 may
be Onwhen installing or removing the FXS+ Quad and Dual
Voice option modules.
