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.

Chapter 3. Operation

Port Configuration Menu Items and Their Choices

Mode

Mode sets the type of 2-wire to T1 signaling and super­vision to be used. Choices include:

• FXS_LS
This mode sets the port to use FXS loop-start type
signaling on the T-Span and loop-start supervision on
the analog 2-wire interface. This mode supports far­end disconnect by removing tip-ground during the call
if signaled to do so over the T-span. When used with
an ADTRAN FXO+, this feature allows line-current
drop-outs to be passed on to equipment connected to
the FXS+ 2-wire port. Ringing cadence will follow that
provided over the T-span or detected by the FXO port
at the far-end.

• FXS_LSMW
This mode operates as FXS-LS but with the additional
feature of being able to illuminate the message-waiting
light on a message-waiting telephone if used in
conjunction with an ADTRAN FXO+ on the far end.
This feature requires the T-span to be operated on ESF
framing. When any port uses this mode in a slot,
ringing is scheduled to a common two second on, four
second off cadence, for all ports in that slot.

• FXS_GS
This mode set the port to use FXS ground start on the
T-span and ground-start supervision on the analog
2-wire interface. Ground start operation is often used
with trunk interfaces to PBX and key systems to
prevent glare conditions. Ringing cadence will follow
that provided over the T-span or detected by the FXO
port at the far-end.

• TANDEM_LS
This mode sets the port to use E&M signaling on the
T-Span and loop-start supervision on the analog
2-wire interface. When using this mode, line-current
drop-out for 500 ms is provided when a call termi­nates and the far-end hangs up. This may be useful
for voice-mail or modem systems that need far-end

18 FXS+ Dual Voice Option Module 61200.080L1-1

Chapter 3. Operation

disconnect supervision. This mode also requires other
options to be selected. These options are: supervi­sion, dial tone, loop reverse battery, and ringback.
These options are described in detail elsewhere.
Ringing cadence for incoming calls is two seconds on,
four seconds off.

• TANDEM_GS
This mode sets the port to use E&M signaling on the
T-Span and ground start supervision on the analog
2-wire interface. Ground-start operation is often used
with trunk interfaces to PBX and key systems to
prevent glare conditions. Appropriate TANDEM
options must be chosen in this mode as described for
TANDEM_LS. Ringing cadence for incoming calls is
two seconds on, four seconds off.

• PLAR
This mode sets the port to use PLAR signaling on the
T-span and loop-start supervision on the analog
2-wire interface. This mode is used to provide a point­to-point hot line, so that when one telephone is lifted
off-hook, the telephone at the other end rings until it
is also picked up. When both ends are off-hook, a
direct point-to-point connection is established.
Ringing cadence is two seconds on, four seconds off.

RX L VL (TLP) (Receive Level/Transmit Level Point)

RX LVL (TLP) sets the RX direction transmission level
points (TLP). The TLP is indicated in dBm and the
relative loudness is indicated by a bar graph display.
Settings change immediately as the bar graph is scrolled.

Choice range:

• –8Bm to 0dBm, in 1dB steps

TX L VL (TLP) (Transmit Level/T ransmit Level Point)

TX LVL (TLP) sets the TX direction transmission level
points (TLP). The TLP is indicated in dBm and the
relative loudness is indicated by a bar graph display.
Settings change immediately as the bar graph is scrolled.

Choice range:

• +3 dBm to –5 dBm, in 1dB steps

61200.080L1-1 FXS+ Dual Voice Option Module 19

Chapter 3. Operation

Fault Resp (Fault Response)

Fault Resp is used to set the 2-wire response to a carrier
alarm. For a network alarm, the ground start 2-wire
trunk would appear busy if Fault Resp is set to seized. If
set to normal, no seizure of a ground start trunk occurs.

Choices include:

• Normal

• Seized

T andm Options (Tandem Options)

Some options are valid only when operating in the
tandem mode. These options are provided below.

• Supervision
Supervision sets the supervision method used when
the card is configured to operate in the Tandem mode.

Choices include:

- Immediate

- Wink

• Dial Tone
Dial Tone is used to enable or disable the on-board
dial tone generation when the FXS+ is operating in the
tandem mode. When the on-board dial tone genera­tion is enabled, the dial tone will turn off after a five
second time-out.

Choices include:

- Enabled

- Disabled

• Loop Reverse Battery
This option causes the polarity of tip and ring to be
reversed when the far-end answers and the FXS+ card
is set to TANDEM_LS mode. This provides answer
supervision to the 2-wire port.

Choices include:

- Enabled

- Disabled

20 FXS+ Dual Voice Option Module 61200.080L1-1

Chapter 3. Operation

• Ringback
This option generates ringback tone towards the
T-span when enabled and the FXS+ card is in one of
the Tamden modes. This may be needed on some
cases when the network does not provide ringback
tone.

Choices include:

- Enabled

- Disabled.

Run Self Test, a submenu of the TSU 100/600 Main
menu item Test, executes both the FXS+ internal test
and the TSU 100/600 internal test. The results of the
self test are displayed in the LCD. See the TSU 100/600
User Manual for additional information on Self Test.

Chapter 3. Operation

When Run Self Test is displayed, place the cursor on it
and press Enter to execute the test. The unit continu­ously changes the display in the LCD window until all
