SUBJECT TO ELECTROSTATIC DAMAGE  
OR DECREASE IN RELIABILITY.  
HANDLING PRECAUTIONS REQUIRED.  
CAUTION  
Electrostatic Discharge (ESD) can damage electronic modules.  
When handling modules, wear an antistatic discharge wrist strap  
to prevent damage to electronic components. Place modules in  
antistatic packing material when transporting or storing. When  
working on modules, always place them on an approved antistatic  
mat that is electrically grounded.  
After unpacking the NTU-8F, inspect it for damage. If damage has occurred, file a claim with  
the carrier then contact ADTRAN Customer Service. Refer to ”Appendix A, Warranty” for  
further information. If possible, keep the original shipping container for returning the NTU-8F  
for repair or for verification of shipping damage.

Power Interface  
The power for the NTU-8F can be supplied through a –48 VDC supply connected to the  
backplane of the NTU-8F. The NTU-8F operates within a voltage range of –42 VDC to –56 VDC.  
Loop Connections  
The E1 loop connections are made through four RJ-45 type connectors. For each connector,  
transmit tip and ring are on pins 5 and 4, and receive tip and ring are on pins 2 and 1, respec-  
tively. Single-mode fiber is connected to the SC connector located on the back panel of the  
module.

Total Access 3000/3010 NTU-8 Single Fiber Quad E1 Installation and Maintenance Practice  
Physical Installation  
To install the NTU-8F, perform the following steps:  
1. Place the unit in a location where a DC power source is available. This unit operates  
within a voltage range of –24 VDC to –48 VDC. If a wall-mount installation is required,  
attach the supplied hangers to the unit.  
2. Connect power to the NTU-8F housing. Power is connected to the NTU-8F by connecting  
the plus (+), minus (–), and ground wires to a three-position terminal block located at the  
right of the backplane (see Figure 2).  
Figure 2. NTU-8F Rear Panel  
When the NTU-8F first powers up, it runs power up self-tests. Once the power up self-test is  
complete, the status LEDs will reflect the true state of the hardware.  
Front Panel LEDs  
The NTU-8F provides front panel LEDs to display status information. The NTU-8F LEDs and  
status descriptions are shown in Table 2.

Total Access 3000/3010 NTU-8 Single Fiber Quad E1 Installation and Maintenance Practice  
PROVISIONING  
The NTU-8F is automatically configured to match the LTU-8 settings and does not require local  
provisioning. Provisioning for the LTU-8 is via the Total Access 3000/3010 System Controller  
Unit (SCU). The SCU initiates and controls the transfer of commands and data to and from the  
LTU-8. The LTU-8 generates all menu items for both the LTU-8 and the NTU-8F. The LTU-8  
retains provisioning data in a nonvolatile memory device in the event of power loss.  
Viewing of all provisionable settings, status, and Performance Monitoring menus are supported  
from the NTU-8F local craft port, labeled CRAFT, but changes cannot be made. The craft port is  
a DB-9 connector that supplies an RS-232 interface for connection to a controlling terminal.  
The supported terminal type is VT100 or compatible and is set for the following:  
• 38400 bps  
• 8-data bits  
• no parity  
• no flow control  
• 1-stop bit  
Y-Modem flash upgrade is password protected from the NTU-8F. The default password is  
“password,” which can be changed from the NTU-8F.  
Provisioning Defaults  
On initial installation, the NTU-8F is set to factory default provisioning options. Table 4 list  
available options, with the default settings shown in bold type.

Total Access 3000/3010 NTU-8 Single Fiber Quad E1 Installation and Maintenance Practice  
OPERATION  
The NTU-8F provides a platform to exchange data between four G.703 interfaces and an  
optical fiber interface. The customer data connection is via the RJ-45 connector on the unit.  
An optical fiber interface is provided for communication with the loop. The NTU-8F operates  
with an LTU-8 at the other end of the fiber optic cable.  
FRONT PANEL PUSHBUTTON  
Pushbuttons on the front panel (Table 5) provide the following functionality (when the option  
is enabled on the LTU-8).  
Table 5. Front panel Pushbuttons  
Pushbutton  
Port Select  
Function  
Press the PORT SELECT button to select the active port. Selection  
choices cycle through the provisioned G.703 E1 ports in following  
order:  
No Port, Port 1, Port 2, Port 3, and Port 4.  
Local Loop/ERR INJ  
Remote Loop  
With a port selected, and a Bit Error Rate Test (BERT) is not in  
progress, press the LOCAL LOOP/ERR INJ button to either initiate or  
terminate a local loop on the selected port.  
If a BERT is in progress, press the button to inject a single bit error.  
With a port selected, press the REMOTE LOOP button to place or  
remove a remote loop on the selected port's single data service. This  
action sends respective inband loop-up or loop-down patterns to  
the far end (in the associated data service timeslots).  
BERT  
With a port selected, and no local loops, press the BERT button to  
start or stop a BERT on the selected port.
