1. GENERAL

This practice provides installation and maintenance
information for the ADTRAN® Intelligent 2-Wire Foreign
Exchange Station/Dial Pulse Originate (2FXS/DPO PM)
Dataport with Performance Monitoring, part number
1109403L2. It is a D4 compatible channel unit and
operates in any standard D4 channel bank. Intelligent
features requires the unit to be used in the ADTRAN ACT
2300, ACT 1900 , or standard WECO® D4 channel bank
using the ADTRAN LIU-3/PM common unit. The 2FXS/
DPO PM provides an interface between a D4 channel
bank Pulse Code Modulation (PCM) backplane interface
and a 2-wire voice frequency (VF) transmission and
signaling facility. Figure 1 is an illustration of the 2FXS/
DPO PM. The unit is multifunctional and can be
provisioned to operate in the following modes:

• 2-Wire Foreign Exchange Station (2FXS)

• Dial Pulse Originate (DPO)

• Tandem FXS Mode

• Private Line Auto Ringdown (PLAR)

Figure 1. 2FXS/DPO

Using the FXS/DPO PM in an intelligent channel bank
provides additional features and functions such as:

• Local and Remote Provisioning using either the craft
interface or ADTRAN Site Manager through a menu
driven program called EASYMENU™

• Performance monitoring of the loop

• Network and customer side monitoring and analysis

• Enhanced Test Capabilities

Revision History

Revisions to this practice include CLEI code and dip
switch settings.

Features

• Backplane interface to the Pulse Code Modulation
(PCM) bus.

• On board coder/decoder (CODEC) uses µ-law
encoding/decoding.

• Nominal 600 ohm or 900 ohm 2-Wire VF interface with
DC isolation.

• Tandem or private line automatic ringdown mode with
D3 or D4 signaling.

• Transmit and receive gain/attenuation adjustable in

0.1 dB increments.

• Transmit input range of -4.5 to 1.8 dBm.

• Receive output range of -6.3 to 0.0 dBm.

• Complies with AT&T Publications 43801, 41008,
41009, and Bellcore GR-1089-CORE requirements
for Type 1 Equipment.

• Supports Calling Number Delivery and other common
(CLASSTM) service offerings according to TR TSY
000030 section 3.3.1.1.

2. INSTALLATION

After unpacking the unit, immediately inspect it for
possible shipping damage. If damage is discovered, file
a claim immediately with the carrier and then contact
ADTRAN customer service (see

Customer Service

).

Add Attenuation

Note 1: Factory default setting for all switches is "off."
Note 2: Multiple switch activation causes a cumulative effect

on the amount of attenuation added.

Note 3: The largest transmit attenuation value in 2-Wire

mode is 6.3 dB.

"On" Position

The 2FXS/DPO PM plugs directly into an ADTRAN ACT
2300/1900 or standard D4 channel bank. No installation
wiring is required. To install, grasp the 2FXS/DPO PM by
the faceplate and insert it into the backplane connector
until firmly seated.

Provisioning Options

Most options on the 2FXS/DPO are provisionable either
manually, using internal slide switches, or electronically
using a menu-driven program called EASYMENU. The
trunk processing options are found on internal slide
Switch 7 (SW7) and can only be provisioned manually.

Manual provisioning should be completed before
the 2FXS/DPO is inserted into the channel
bank. Electronic provisioning should be
completed following installation.

Manual Provisioning

Internal slide switches SW1,2, 3, 4, and SW7 are used to
manually provision and set the operational modes and
options of the unit. Figure 1 displays switch locations.

Slide switches SW1 and SW2 are used to set, receive, and
transmit attenuation. Table A displays the available options.

Slide switches SW3-1, 2, 3, 4, and SW3-5 are used to
provision the desired operation mode of the unit.

Slide switch SW4 is used to provision the trunk processing
(SD), dial pulse correction (DPC), loop or ground start (GS),
PLAR mode (PD3), tandem battery mode (TRB), tandem
start mode (TWS), dial tone (DTG), and ringback tone
(RTG).

Slide switch SW7 is used to provision the trunk processing
options: make busy lead (1G), make busy closure (L), and
busy trunk sleeve (S). Table B summarizes the option
settings for SW3, SW4, and SW7.
