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
featuresrequirestheunittobeusedintheADTRANACT
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
bankPulseCodeModulation(PCM)backplaneinterface
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:
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.
• Nominal600ohmor900ohm2-WireVFinterfacewith
DC isolation.
• 2-Wire Foreign Exchange Station (2FXS)
• Dial Pulse Originate (DPO)
• Tandem FXS Mode
• Private Line Auto Ringdown (PLAR)

(SW3-5)
Note: X = Switch position is ignored.
For example, if an input TLP level of -3 dB is to produce
a level of 0dBm0 at TLP0, then the Transmit Attenuation
should be set to 1.5 dB.
Electronic Provisioning
ADTRANEASYMENU isusedtoelectronicallyprovision
the unit. Connect a VT 100 terminal or a computer
running a terminal emulation program to the faceplate
ADMIN port or REMOTE port using a standard male-to-
male RS-232 cable. The settings for the ADMIN and
REMOTE ports are shown in Table D.
Receive Attenuation
Determine the output TLP. Then use the following
formula to calculate the amount of receive attenuation to
add to the circuit:
Rx Attenuation=Internal Rx TLP of 0 dBm) - Output
TLP
A null modem cable is required to connect the
REMOTE port directly to a terminal.
For example, if 0dBm0 at TLP0 is required to produce an
Output TLP level of -3 dB, then the Receive Attenuation
should be set to 3 dB. Figure 2 provides an illustration
of attenuation settings.

The 2FXS/DPO PM has four faceplate indicators and a
depressed provisioning switch. The front panel PM

control link establishment and remains ON after the
channel unit has been remotely provisioned.

Customer Ringing Test
The Customer Ringing Test will activate the unit's ring
relay in a 2-on/4-off ring cadence, providing ringing to
the customer loop when a ring generator is properly
connected to the channel bank.
The REM indicator remains ON when the channel unit is
operating based on Remote Provisioning, and is OFF
when based on manual switches. If the channel unit has
never been remotely provisioned, the AP switch has no
effect and the REM indicator remains OFF . The REM
