The NTU-8F is a standalone remote network terminal unit that provides for transport four,
short-haul E1 (G.703) channels, and a 10Base-T or 100Base-T (10/100) Ethernet interface
that can be multiplexed over a single-mode fiber optic cable to a Total Access 3000/3010 LTU-
8 Single Fiber Quad E1 with Ethernet and Performance Monitoring (P/N 1182300E1). The
LTU-8 is located in the Central Office. The NTU-8F is provisionable remotely from the LTU-8.
Provisioning can be viewed locally and flash upgrades can be initiated by using a VT100 craft
interface.
Features
The basic features of the Total Access 3000/3010 NTU-8F include the following:
• E1 Status for all channels
• Loopback Status
• Optical port status

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
further information. If possible, keep the original shipping container for returning the NTU-8F
for repair or for verification of shipping damage.
Shipping Contents
The contents include the following items:
• NTU-8F
• Total Access 3000/3010 NTU-8 Single Fiber Quad E1 with Ethernet and Performance
Monitoring Compliance Document (P/N 61182301E1-17)
• Total Access 3000/3010 NTU-8 Single Fiber Quad E1 with Ethernet and Performance
Monitoring Job Aid (P/N 61182301E1-22)
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
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

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.

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.

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.
