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.

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.

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.
