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

(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 Network On-hook/Off-hook test is used to test  
signaling sent to the network by the unit. When On-hook

When Off-hook Test is selected, Off-hook signaling is  
sent to the Network. The customer loop is forced On-  
hook while this test is active.  
The 2FXS/DPO PM has four faceplate indicators and a  
depressed provisioning switch. The front panel PM  
(Performance Monitoring) indicator Flashes during  
control link establishment and remains ON after the  
channel unit has been remotely provisioned.  
If the channel unit has been remotely provisioned, the  
operatorcanalternatebetweentheremoteconfiguration  
data stored in nonvolatile memory or manual switch  
settings by pressing the momentary AP (Alternate  
Provisioning) switch located on the front panel.  
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

1004 Hz DRS Tone Generation Test  
The 1004 Hz DRS (Digital Reference Signal) Tone  
Generation test is used to send the DRS signal to the
