Chapter1
Introduction
FXS+ DUAL VOICE OVERVIEW
The FXS+ Dual Voice (FXS+) option module is one of
the option modules available for use with theADTRAN
TSU 100/600. The FXS+ module provides two 2-wire
voice-grade interfaces serving as the source of line-
current 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 anADTRAN FXO+, analog message-
waiting functions may be extended over the T-span to an
analog message-waiting telephone. The FXS+ card
provides the necessary voltages to light the message-
waiting light.
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.

Chapter1. Introduction
2FXS+ Dual Voice Option Module 61200.080L1-1
Functional Description

600 or by an external personal computer (PC) program.
The internal menus for its configuration are a part of the
FXS+ module and are automatically installed when the
FXS+ is plugged into the unit.

option slot in the rear of the TSU 100; see Figure 1-1.
PORT X.3
DUAL FXS
PORT X.1 PORT X.2
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
contactADTRAN 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
Modules With Hot Replaceable Label on Back Panel
For ease of replacement, power to the TSU 100/600 may
be On when installing or removing the FXS+ Dual Voice
option module with a Hot Replaceable label on the back
panel .

Chapter2. Installation
61200.080L1-1 FXS+ Dual Voice Option Module 9
Modules Without Hot Replaceable Label on Back Panel
Power to the TSU 100/600 must be Off when installing
or removing the FXS+ Dual Voice option module without
a Hot Replaceable label on the back panel.
Placement of the Option Module
Figure 2-1 represents the action required for proper
placement of the option module.
1. Remove cover plate from the TSU 100/600 rear
panel.
2. Slide option module into the rear panel until it is
positioned firmly against the front of theTSU100/600.
3. Fasten thumbscrews atboth edgesof the option
module.

POWER UP TESTING AND INITIALIZATION
The FXS+ option module executes an abbreviated self
test during the power up sequence, as described in the
TSU 100/600 manual. No initialization input is
required. Any previously configured setting for the
FXS+ is restored automatically upon power up.
Successful Self Test
The green OK LED, located with the Module LEDs on
the front panel, illuminates when a successful self test is
completed and the configuration is successfully restored.
See the section Front Panel Operation in the TSU 100/600
User Manual.
Failed Self Test
If the FXS+ module fails one or more of the self tests a
message is displayed in the LCD during power up. See
TSU 100/600 User Manual. Specific failures of the FXS+
module are identified in the appendix FXS+ Failure
Messages in this manual.
Operation Alarms
The red ALARM LED with the Module LEDs on the front
panel illuminates when an alarm condition is detected.
Configuration of TX Level (TLP)
For any installation where the analog channel (DS0)
terminates within the Public Switched Telephone
Network, the TX LVL should be set to +3 dBm. For
point-to-point applications where the channel terminates
in other customer equipment, any TX LVL may be used.
A +3 dBm TLP setting attenuates the analog signal
by 3 dB.
