NOTE: The system automatically maps DS0s in the T1 as determined by the LIU 

operational configuration. Automatic assignment can be overridden by 
manually changing the T1 mapping in the LIU menu system.

PROVISIONING

The Dual FXS/DPO supports remote provisioning only, and is provisioned 
through the common equipment ADMIN port of the Total Access 1500 System 
Controller Unit Remote Terminal (SCU RT, P/N 61180008Lx). To connect a 
VT100-compatible terminal to the ADMIN port for provisioning, testing, and 
performance monitoring functions, complete the following steps:

1. Connect a DB-9 cable to the DB-9 CRAFT port.

2. Run a terminal emulation program. If using Windows Hyperterminal, open 

the program by selecting Programs>Accessories>Hyperterminal.

3. Log in and navigate through the ADMIN port menu structure to the Dual 

FXS/DPO provisioning options and perform the desired function.

NOTE: To ensure proper display background, select VT100 Terminal Emulation 

under Settings.

NOTE: To traverse through the menus, select the desired entry and press 

Enter

To work backwards in the menu, press

TESTING

To test the operation of the Dual FXS/DPO, initiate tests through the Total 
Access 1500 SCU ADMIN port. The table below describes the available tests.

Test

Purpose

Network On-Hook/Off-Hook Test

This test sends on/off hook signaling to 
the network.

Digital Loopback Test

This test loops back DS0 data coming 
from the network.

Customer Ring Test

This test activates the unit ring relay in a 
2-on / 4-off ring cadence, providing 
ringing to the customer loop.

1004 Hz DRS Tone Generation Test

This test sends the DRS signal to the loop, 
to the network, or to both simultaneously.

DESCRIPTION

The Dual Foreign Exchange Station and Dial Pulse Origination unit (Dual FXS/
DPO, P/N 1180208L2) is used for analog voice extension and DID circuits. The

the following features:

Dual independent FXS/DPOs on a single card

FXS, DPO, PLAR, TR08 SP, TR08 UVG, Tandem, and TO with Sealing 

Current operating modes

Loop Start, Ground Start, and Wink Start signaling modes

Custom Local Area Signaling Services (CLASS

™)

 compatibility

Digital loopback to network, via site manager or craft interface

INSTALLATION

After unpacking the Dual FXS/DPO, inspect it for damage. If damage is noted, 
file a claim with the carrier and then contact ADTRAN. For more information, 
refer to the warranty.
To install the Dual FXS/DPO, complete the following steps:

1. If present, remove the Access Module Blank (P/N 1175099L1) from the 

appropriate access module slot of the Total Access 1500 chassis.

2. Pull the ejector latch, located on the lower left-hand side of the Dual FXS/

DPO front panel, from its closed position.

3. Hold the Dual FXS/DPO by the front panel while supporting the bottom edge 

of the module with the ejector latch opened to engage the chassis edge.

4. Align the module edges to fit in the lower and upper guide grooves for any 

access module slot 1-24.

5. Slide the module into the access module slot. Simultaneous thumb pressure 

at the top and at the bottom of the module will ensure that the module is 
firmly positioned against the backplane of the chassis. 

6. Secure the Dual FXS/DPO in place by pushing in on the ejector latch.

When the Dual FXS/DPO first powers up it runs a power up self-test. Once the 
power up self-test is complete, the status LEDs will reflect the operational state 
of the hardware. Monitor the LEDs for operational status.
