FXS+ DUAL VOICE OVERVIEW
The FXS+ Dual Voice (FXS+) option module is one of
the option modules available for use with the ADTRAN
TSU 100/600. The FXS+ module provides two 2-wire
voice-grade interfaces serving as the source of linecurrent and ringing voltage to a telephone or station
interface. The FXS+ may serve as the station-side of a
foreign exchange fxs/fxo application.
When used with an ADTRAN FXO+, analog messagewaiting functions may be extended over the T-span to an
analog message-waiting telephone. The FXS+ card
provides the necessary voltages to light the messagewaiting light.
Chapter 1. Introduction
Chapter 1
Introduction
The FXS+ may also be paired with another FXS+ to
provide a hot-line 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 (e.g., 1-800 services, Megacom®) using E &
M signaling on the T-span. 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. Signaling and
interfaces comply with portions of EIA/TIA-464-A,
T1.401, and AT&T Pub. 41458 and Pub. 43801.
The FXS+ option module also accepts the FXS+ plug-on
board to provide up to four FXS+ functional ports per
option slot used.

Physical Description
The FXS+ is an option module which plugs into the
option slot in the rear of the TSU 100; see Figure 1-1.
Chapter 1. Introduction
DUAL FXS
PORT X.1
PORT X.2
PORT X.3
Figure 1-1
FXS+ Dual Voice Option Module
The FXS+ rear panel includes a plastic plug over a cutout
for additional connectors. This allows a plug-on board
to be added to the FXS+ module. The PORT X.3
indication is linked to the port numbering philosophy of
the TSU 100 product family. The X represents 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 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.

INSTALLING THE FXS+ DUAL VOICE OPTION MODULE
Determine Revision Level of TSU 100 / TSU 600
FXS+ Dual Voice Module (Software Revision K and
above) can only be fully supported in TSU 100 units of
Software Revision L (and later) and TSU 600 units of
Software Revision F (and later). To determine the
software revision in the TSU, follow these steps:
1. Power the TSU On.
2. Using the front panel keypad, select Main menu item
3 (UTIL) which gives you the Utility menu.
3. From the Utility menu, select menu item 5 (Software
Revision).
4. The unit will display the revision of the operating
software.
If the card is to be installed in a TSU 100 or TSU 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
assistance with software revision upgrades, please
contact ADTRAN Technical Support at
1-800-726-8663.
Before installing the module, check the back panel for the
presence or absence of a Hot Replaceable label on the back
panel
