Description

The QDFR is a customer premise fiber optic access unit. The QDFR is designed to provide four T1 interfaces that can be multiplexed together over a single mode fiber optic cable to a Total Access 3000 Quad Fiber Central Office (QDFC) Module (P/N 1181308L7).

The QDFR is specifically designed to provide a high degree of resistance to damage typically caused by Ground Potential Rises (GPRs). This is accomplished by having the network interface optically isolated from the customer side and the DS-1 interfaces having over 6 kilovolts of isolation with respect to ground. The QDFR is virtually immune to the effects of GPRs compared to other network interface equipment.

HANDLING PRECAUTIONS REQUIRED.

After unpacking the QDFR, inspect it for damage. If damage has occurred, file a claim with the carrier then contact ADTRAN Customer Service. Refer to “Appendix C, Warranty” for further information. If possible, keep the original shipping container for returning the QDFR for repair or for verification of shipping damage.

SHIPPING CONTENTS

The contents include the following items:

•QDFR Unit

• Quad Fiber Remote (QDFR) Unit Job Aid (P/N 61181307L7-22)

CAUTION

Electronic modules can be damaged by ESD. 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.

Installing the QDFR

To install the QDFR, 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.

2. Using the hex nut and lock washer supplied with the QDFR, attach a grounding strap to the grounding lug on the left side of the QDFR chassis. Finger-tighten only.

3. Conned power to the QDFR by connecting the plus (+), minus (–), and ground wires to a three-position terminal block located at the left of the backplane (Figure 2). The DS1 loop connections are made through four RJ-48C type connectors. Single-mode fiber is connected to the SC-type connector located at the right of the backplane.

When the QDFR first powers up, the unit initializes a self test that lasts for approximately 30 seconds. After the self test is completed, the LEDs reflect the current status of the unit.

Front Panel LEDs

The QDFR provides front panel LEDs to display status information for the unit. Table 2 lists the front panel LEDs and their indications.

Loop Connections

LOOP CONNECTIONS

The T1 loop connections are made through four RJ-48C 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. The single-mode fiber is connected to the SC connector located on the back panel of the unit.

OPERATION

The Quad Fiber Remote (QDFR) Unit provides a platform to exchange data between four Tls and an optical fiber interface. The customer data connection is via the RJ-48C connectors on the unit. An optical fiber interface is provided for communication with the loop. The Quad Fiber Remote (QDFR) Unit operates with a QDFC module at the other end of the fiber optic cable. The figure below illustrates the pin-out configuration for the RJ-48C connectors.

Menu Structure

MENU STRUCTURE

The menu structure for the QDFR is a layered menu tree. Each layer of the menu tree is displayed as a menu or a screen.

Screen

A screen is a display that usually indicates the end of a menu tree path. A screen can contain the following objects:

• Read-only Field: A read-only field displays information that cannot be changed. The information displayed in a read-only field can be static or can be automatically updated by the QDFR.

• Read-write Field: A read-write field displays information that when selected can be modified.

• Hot Key: A hot key is a key or combination of keys that are assigned to a function. Hot keys are indicated by the required key(s) and a brief description (i.e., N - Next Channel).

MENU NAVIGATION

Basic menu navigation is accomplished by selecting the desired option number and then pressing

ENTER. To return to the previous menu, press the ESC (escape) key.
