  • Page 14: Applications

    Litespan H2TU-C Installation and Maintenance Practice APPLICATIONS The Litespan H2TU-C can be deployed in circuits consisting of one H2TU-C (line card) and one H2TU-R (remote module). Lightning and power cross-protection is provided at each twisted pair interface of the Litespan H2TU-C. Local power bus fusing protects the Litespan channel bank backplane, Litespan bank power supplies, and neighboring Litespan line cards in the event of catastrophic line card failure.

  • Page 27: Hdsl2 Loopbacks

    In general, the loopback process for the HDSL2 system elements is modeled on the corre- sponding DS1 system process. Specifically, the H2TU-C loopback is similar to an Intelligent Office Repeater loopback and the H2TU-R loopbacks are similar to a T1 NIU.

  • Page 28: Table A-1. In-Band Addressable Loopback Codes

  • Page 32: Overview Of Tl1 Structure

    Litespan H2TU-C Installation and Maintenance Practice OVERVIEW OF TL1 STRUCTURE TL1 commands are used to perform administrative, maintenance, and provisioning tasks on Litespan systems. Commands may be issued from a simple computer terminal (often referred to as a craft interface), by a microcomputer running an appropriate terminal emulation program, or by a higher level system capable of issuing TL1 commands in the proper format (such as a Litecraft PC terminal, AMS, or other operations support system software).
  • Page 33 Appendix B, Litespan H2TU-C Provisioning Tutorial - Overview of TL1 Structure 1. The semicolon (;) is the message terminator. Entry of a semicolon prompts immediate issue of the preceding string for execution. 2. Colons (:) are data block delimiters. They enclose and separate data blocks that are composed of one or more parameters (data units).

  • Page 34: Communication With The Litespan System

    Litespan H2TU-C Installation and Maintenance Practice COMMUNICATION WITH THE LITESPAN SYSTEM To communicate with the Litespan system, log on by providing a unique user identification (UID) and private identification (PID, or password) code for verification by the system. In addition, the appropriate security privileges are necessary to perform the desired operations.
