    CHAPTER 4: Installation To modify the DCE/DTE orientation from the default position (DCE), you must open the X.21 Line Driver’s case. 4.3.2 O PENING THE To open the Line Driver’s case, insert a flat-head screwdriver into an open slot on both sides of the case, as in Figure 4-5.

  • Page 19: Connecting Power

    The Line Driver powers up as soon as it is plugged into an AC outlet; there is no power switch. WARNING There are no user-serviceable parts in the power supply. Only qualified service personnel should replace the fuse. Contact Black Box Technical Support at 724-746-5500 for details.

  • Page 20: Operation

    CHAPTER 5: Operation 5. Operation Once the Line Driver is properly configured and installed, it should operate transparently. This chapter describes power-up, reading the LED status indicators, and using the built-in loopback test modes. 5.1 Power-Up To apply power to the Line Driver, first be sure that you have read Section 4.4. The unit powers up when it is plugged into the power source.

  • Page 21: Test Modes

    2-WIRE SHORT-RANGE DSL LINE DRIVER (HDSL WITH V.35 OR X.21) • ER: blinks ON/OFF after a 511/511E test has timed out. See Section 5.3 for more information. ER flashes once to indicate that a CRC error has occurred (during normal operation) or bit errors have occurred (during 511/511E tests).

  • Page 22: Restart Procedure And Timeouts

    CHAPTER 5: Operation Framer The framer is used to determine the status of the line. In normal operation, the framer transmits and expects to receive framed packets from the far end. If the framer receives framed packets from the far end, CTS and CD will be active. If framed packets are not received, CTS and CD will be inactive.

  • Page 24 CHAPTER 5: Operation the line or at the far-end DTE interface is invalid. The remote unit will remain in the startup mode, NS LED on, CTS LED yellow, and CD LED yellow, until the local unit is taken out of the local loop mode. After the local loop is deselected, the units will both be in startup mode and the link will be established.
  • Page 25 2-WIRE SHORT-RANGE DSL LINE DRIVER (HDSL WITH V.35 OR X.21) Local Loop with 511/511E When the unit is placed into a mode 1 local loop and the 511/511E pattern generator is activated, the local pattern generator begins sending out a 511/511E pattern to the loop control block.

Remote Digital Loop The Remote Loop uses the EOC channel (an out-of-band signaling channel) to establish the remote link. Upon the RDL switch being thrown or DTE initiation, a RDL_ON Request signal is sent to the remote unit.
  • Page 27 2-WIRE SHORT-RANGE DSL LINE DRIVER (HDSL WITH V.35 OR X.21) Remote Digital Loop with 511/511E The Remote Digital Loop with 511/511E is shown in Figure 5-8. After RDL is established, the remote unit’s restart timer is set to one minute. This has been done because when the 511/511E generator is started on the local unit, the remote framer begins seeing unframed packets.
