  • Page 11: Overview

    150-200-124-02, Issue 2 Overview VERVIEW ® The HiGain HLU-200 List 2D is a HiGain Line Unit (HLU) that plugs into any channel unit slot of a ® Litespan 2000 Channel Bank Assembly (CBA). Within Litespan, it is called an Asynchronous High-bit-rate Digital Subscriber Line (AHDSL) channel unit.
  • Page 12 Overview 150-200-124-02, Issue 2 The HLU-200 List 2D is compatible with Litespan 2000 system software (Release 8.2 and later) and the TL1 based Litecraft Integrator Management System; the unit must be maintained, provisioned, and monitored from the Litecraft/TL1 since it cannot be managed from the front panel RS-232 craft port. (The front panel RS-232 craft port is used only for factory testing.) The HLU-200 List 2D works asynchronously with the Litespan bank timing.

  • Page 15: Functional Description

    Is steady Yellow during self-test UNCTIONAL ESCRIPTION The HiGain system uses ADC’s 2B1Q HDSL transceivers to establish two full-duplex 784 kbps data channels between the HLU-200 and an HRU remote unit. This provides a total capacity of 1.568 Mbps between the two units.
  • Page 16 Functional Description 150-200-124-02, Issue 2 The Test Loop feature allows metallic test access to the two facility cable pairs as shown in Figure Figure 3. HLU-200 List 2D Block Diagram The HLU-200 List 2D contains an HDSL framer that generates two parallel 784 kbps data streams. The data streams contain HDSL frames that are nominally 4704 bits (6 milliseconds) in length.
  • Page 17 150-200-124-02, Issue 2 Functional Description The symmetry of the HDSL line powering voltage can be set by the S1 switch, located on the printed circuit board, as shown in Figure The factory default setting is UNI (-). It sets the HDSL line voltage to 0V on Loop 2 and to -130V on Loop 1. This setting keeps the HDSL cable pair voltages at or below ground potential, thereby avoiding corrosion problems caused by cable voltages more positive than ground.

HLU-200 NSTALLING THE To install the HLU-200, follow these steps: Hold the HLU-200 along the edges of the card. Avoid contact with connectors and chips. Slide the card into the guides for the desired slot.

    150-200-124-02, Issue 2 Managing the HLU-200 The dormant state occurs because the rapid re-insertion inhibits the CBA's ability to detect the unit’s removal. The CBA must find the slot empty for three consecutive polling inquiries before it declares the slot empty. If the unit is removed and re-inserted before three polling periods occur, the CBA does not detect the removal and the unit enters a dormant state.

The block diagram of this function is shown in Figure 3 on page 6. Each of the two HDSL loops (Loop 1 and Loop 2) from the outside cable pairs pass through a set of relay contacts before they are connected to the HLU-200.

  • Page 41: Notes On Non-Doubler Gnlb Loopback Test Procedures

    HLU-200 may indicate one more or one less bit error, depending on the test set type and the number of frame bits contained in the block of errored bits. To avoid this uncertainty, ADC recommends sending the IR commands unframed.
