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
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 mod-
ules, wear an antistatic discharge wrist strap to prevent damage to
electronic components. Place modules in antistatic packing mate-
rial 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
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 Pushbuttons
The QDFR has two pushbuttons located on the front panel:
• Channel Select (CH SELECT)
• Loopback (LBK)
To initiate a channel loopback at the QDFR, press CH SELECT until the desired channel LED is
flashing, then press LBK to initiate the loopback.
NOTE
This selection only pertains to the test jack and the pushbuttons.
The user may continue to initiate or terminate any loopback on any
channel via the craft port.
• To initiate a loopback at the QDFC, press the LBK pushbutton for at least 3 seconds.
• To terminate active loopback(s), press the LBK switch while any loopback is active.
NOTE
All loopbacks initiated by the QDFR pushbuttons are bilateral.
Data from the port input is sent to the port output, and data from
the network (fiber) is sent back to the fiber.

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, respec-
tively. 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 in-
band 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 corre-
sponding 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
of 1E-03 or better is present.

1. Units must be armed with 11000b or FF48h before this code will work.
2. Loopback and error injection will only occur if the in-band code is received by the unit that is to go into loop-
back. If another loopback blocks the in-band code from being transmitted to the unit that is to go into loopback,
loopback and error injection will not occur.
NOTE
All codes listed above must be sent for a minimum of 5 seconds to
be detected and acted upon.

Appendix B
Rear Panel DS1 Test Access
GENERAL
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 (CH SELECT). The LED for the T1
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 CH SELECT switch until the desired
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.
– If the test direction is “Network”, the Tx and Rx data is to and from the network
equipment.
– If the test direction is set to “Customer”, the Tx and Rx data is to and from the customer’s
equipment. Further description of each mode is found on the following pages.

This is accomplished by accessing the front panel switch or from the craft port interface.
2. After the correct T1 channel is selected, verify that the Test Jack Mode is set to “Monitor”.
If the Test Jack Mode is not set to “Monitor”, change this parameter via the Loopbacks and
Test\Test Port (Bantam Jack) Control\Test Jack Mode screen.
The Intrusive Test Direction parameter is not applicable for this mode. In this mode, the
