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.

SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
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
T
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.

Fiber Loss of Sync
- A Fiber Loss of Sync (FLOS) condition (OPT LED is solid Red) indicates that
end-to-end fiber synchronization does not exist between the fiber devices on a
given loop. The problem can exist for any number of reasons, but is most likely
related to some kind of loop fault.
- The condition could be related to a new installation where the field
equipment has not yet been installed (or it has been removed in error), but it
could also be related to a continuity problem due to facility trouble.
- If the condition is not due to the lack of termination, clear the office by
temporarily connecting an QDFR Remote at the network side of the loop. If
the open condition clears, i.e., the FLOS indication goes away (OPT LED is
extinguished), the problem is beyond that point.

Appendix A
QDFR Loopbacks
FIBER LINE UNIT MAINTENANCE MODES
This appendix describes operation of the optical fiber system with regard to detection of inband and ESF facility data link loopback codes.
Upon deactivation of a loopback, the T1 channel interface will synchronize automatically.
NOTE
Each T1 channel is independent of the others. The user can enable
loopbacks in either direction on any number of T1 channels.
Loopback Process Description
In general, the loopback process for the optical fiber system elements is modeled on the corresponding DS1 system process.
Specifically, the QDFC loopback is similar to an Intelligent Office Repeater loopback, and the
QDFR loopbacks are similar to an in-line T1 Repeater loopback.
The unit can detect the loopback activation or deactivation code sequence only if an error rate
-03
of 1E
or better is present.

Rear Panel DS1 Test Access
GENERAL
Figure B-1 through Figure B-3 provides a graphical description of the test jack functionality
for the QDFR. The test jack can be provisioned to correspond to any of the four T1 channels.
There are two options for selecting the T1 channel to be “connected” to the test jack.
• The first is the front panel switch for channel selection (
channel will flash if that is the selected channel for the test jack.
For example, if T1 channel 4 corresponds to the test jack, the LEDs for DS1 1, 2, and 3
remain solid while the LED for DS1 4 flashes.
To change the selected channel, momentarily press the
channel’s LED indicator flashes.
• The next option for selecting test jack channel operation is from the Loopbacks and
Test\Test Port (Bantam Jack) Control screen. The parameter for this option is Change Test
Port Number.
The test jacks can operate as either a terminate jack, also known as intrusive mode, or as a
monitor jack, also known as non-intrusive mode. The functionality of the test jack is
dependent on the provisioning of Test Jack Mode found under Loopbacks and Test\Test Port
(Bantam Jack) Control.
• If this parameter is set to “Monitor”, the test jack can be utilized to monitor the Tx data
from the network or from the customer.
• If the parameter is set to “Intrusive”, the test jack can be utilized to connect a test set to
allow transmitting and receiving data for troubleshooting purposes.
In Intrusive mode, the direction of the test jack must also be selected. This parameter is
set when Toggle Intrusive Test Direction is changed.
