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.
Quad Fiber Remote (QDFR) Unit Installation and Maintenance Practice Loopback Control Codes A summary of control sequences is given in Table A-1. All codes must be sent for a minimum of 5 seconds to be detected and acted upon. NOTE In all control code sequences presented, the in-band codes are shown left-most bit transmitted first, and the ESF data link codes with right-most bit transmitted first. Table A-1.

Appendix B 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 (CH SELECT). The LED for the T1 channel will flash if that is the selected channel for the test jack.
Quad Fiber Remote (QDFR) Unit Installation and Maintenance Practice MONITOR MODE Monitor Tx to Customer The Rx of the monitor BERT receives data from the TX point of the test jack, Figure B-1. This monitors the data that the customer’s equipment is receiving from the network equipment. TX 432ohm RX TX RX T1 BERT 432ohm Figure B-1. DSX MON, Tx to Customer To set up the QDFR for this mode the following sequence must be performed: 1. Select the correct T1 channel to monitor.
Monitor Mode Monitor Rx from Customer The Rx of the monitor BERT receives data from the RX point of the test jack, Figure B-2. This monitors the data that the customer’s equipment is transmitting to the network equipment. TX 432ohm TX RX RX 432ohm T1 BERT Figure B-2. DSX MON, Rx from Customer To set up the QDFR for this mode, the following sequence must be performed: 1. Select the correct T1 channel to monitor.
Quad Fiber Remote (QDFR) Unit Installation and Maintenance Practice TERMINATE MODE Intrusive Tx to Customer and Rx from Customer NOTE This is an intrusive test and the original data path will be disrupted. The Tx of the BERT connects to the Tx of the test jack. The Rx of the BERT connects to the Rx of the test jack, Figure B-3. The Tx data of the test jack is transmitted to the customer’s equipment while the Rx data from the customer is monitored.
Terminate Mode Intrusive Tx to Network and Rx from Network NOTE This is an intrusive test and the original data path will be disrupted. The Tx of the BERT connects to the Tx of the test jack. The Rx of the BERT connects to the Rx of the test jack, Figure B-3. The Tx data of the test jack is transmitted to the network equipment while the Rx data from the network equipment is monitored. In this mode the monitor jack impedance of 432 ohms is removed from the data path.
