61182301E1-5A Installation Installation N C A U T I O N ! 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. 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, respectively. Single-mode fiber is connected to the SC connector located on the back panel of the module. 61182301E1-5A Total Access 3000/3010 NTU-8 Single Fiber Quad E1 Installation and Maintenance Practice Total Access 3000/3010 NTU-8 Single Fiber Quad E1 Installation and Maintenance Practice 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. Table 2. Front Panel LEDs Label Status Description PWR • • • Off Green Yellow Power supply or fuse failure In Service Out of Service-Unassigned or Maintenance OPT • • • Off Green Red Unit is Out of Service-Unassigned Unit is active and optical interface is synchronized Unit is active, but Rx loss on the optical interface PORT 1-4 • • • • Off Green Yellow Red Port is provisioned Out of Service-Unassigned Port is provisioned and functioning properly Port is in loopback or a BERT is active Port is active with an active major alarm condition 61182301E1-5A Installation Installation Label Status Description LBK • Off No loopback on selected channel • Green Selected G.703 E1 port in local loopback • Yellow Selected G.703 E1 port in remote loopback (PN127 or V.54) • Red Selected G.703 E1 port in local or remote loopback (PN127 or V.54); when no port is selected, this becomes an OR’d summation of all loopbacks on all ports BERT • Off Selected G.703 E1 port BERT not active • Green Selected G.703 E1 port BER, with no errors • Yellow Selected G.703 E1 port BERT active with errors • Red Selected G.703 E1 port active, but not in sync Rear Panel Connections Connectors on the rear panel (Table 3) provide for the following connections: Table 3.

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...
