    QUIKCONNECT HDSL LINE DRIVER 2. Introduction 2.1 Description The QuikConnect HDSL Line Driver provides high-speed 2-wire connectivity to ISPs, PTTs, and corporations using HDSL (High-Density Multi-rate Digital Subscriber Line) technology. Multi-rate DSL offers the ability to deliver the maximum bit rate that a twisted-pair line can accommodate. Supporting multiple line rates from 144 kbps to 1.168 Mbps, the QuikConnect provides “megabyte”...

  • Page 10: Configuration

    CHAPTER 3: Configuration 3. Configuration The QuikConnect HDSL Line Driver is equipped with three sets of eight DIP switches. This chapter describes switch locations and explains all possible configurations. 3.1 Configuring the Hardware DIP Switches The 24 external switches are grouped into three eight-switch sets. They’re externally accessible from the underside of the QuikConnect (see Figure 3-1).

When the Line Drivers are connected, the CP will come up with a pre-defined default configuration (receive recovered clocking). During the handshaking process between the Line Drivers, the CO unit will set the DTE rate/line rate of the CP unit to match its DIP-switch configuration settings.

  • Page 17: Installation

    QUIKCONNECT HDSL LINE DRIVER 4. Installation Once the QuikConnect HDSL Line Driver is properly configured, it is ready to connect to the twisted-pair interface, to the serial port, and to the power source. This chapter tells you how to make these connections. 4.1 Connecting the Twisted-Pair Interface The QuikConnect HDSL Line Driver supports communication between two DTE devices at distances to 4 miles (6.4 km) over 24-AWG (0.5-mm) twisted-pair wire.

  • Page 18: Connecting The Serial Port

    CHAPTER 4: Installation 4.2 Connecting the Serial Port The serial port interface on the QuikConnect HDSL Line Driver uses interchangeable QuikConnect Modules. Each QuikConnect module has a 50-pin card edge connector on one side and a serial port interface on the other. Figure 4- 2 shows how a QuikConnect module plugs into the back of the QuikConnect HDSL Line Driver.

    QUIKCONNECT HDSL LINE DRIVER 5. Operation Once the QuikConnect HDSL 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 QuikConnect, first be sure that you have read Section 4.3. Then power-up the unit via the rear-panel power switch.

  • Page 22: Test Modes

    CHAPTER 5: Operation • ER: blinks ON/OFF after a 511/511E test has timed out. See Section 5.3.3 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). Only at power up, ER blinks once every 200 ms if the DTE Rate is set to unsupported settings.

  • Page 23: Restart Procedure And Timeouts

    QUIKCONNECT HDSL LINE DRIVER 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.

Remote End of an RDL 511/511E Timeout 45 (The pattern generator will automatically turn off after 45 seconds. The ER LED will flash until you turn off the 511/511E switch.) Symbol Indicators This symbol designates the origination or the termination of a data path.

Any data present on the line or at the far-end DTE interface is invalid. The remote unit will remain in the Start-up mode, NS LED on, CTS LED yellow, and CD LED yellow, until the local unit is taken out of the local loop mode.
  • Page 26 CHAPTER 5: Operation 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. The loop control block will loop this data back to the 511/511E pattern detector block, which will evaluate the data for errors.

  • Page 28 CHAPTER 5: Operation 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.
