SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY. HANDLING PRECAUTIONS REQUIRED. After unpacking the Litespan H2TU-C, inspect it for damage. If damage exists, file a claim with the carrier then contact ADTRAN Customer Service. Refer to “Appendix E, Warranty” further information. If possible, keep the original shipping container to return the Litespan H2TU-C for repair or for verification of shipping damage.
Installation On installation, the Litespan H2TU-C runs a series of self-tests. Once the self-tests are complete, the status LEDs reflect the true state of the hardware. Front Panel LEDs The Litespan H2TU-C provides front panel LEDs to display status information.
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.
Backplane Wiring The Litespan H2TU-C plugs directly into a Litespan channel bank assembly channel unit slot. Litespan system software must be version 11.0.0, or later. The tip and ring connections from the H2TU-C to the shelf are made through the following card edge pins: •...

LED should immediately turn red. The STAT STAT LED remains red until the Litespan bank recognizes the insertion of the Litespan H2TU-C and downloads the AHDSL2 channel unit type code into the line card. Typically, the STAT remains red for approximately 15 to 20 seconds (this time may vary). Approximately three to...

HDSL2 Deployment Guidelines HDSL2 DEPLOYMENT GUIDELINES The ADTRAN HDSL2 technology provides DS1-based services over loops designed to comply with carrier service area (CSA) guidelines. The CSA deployment guidelines are as follows: 1. All loops are nonloaded only. 2. For loops with 26-AWG cable, the maximum loop length including bridged tap lengths is 9 kilofeet.
Litespan H2TU-C Installation and Maintenance Practice Table 10 summarizes the loop loss per kilofoot for standard wire gauges. Table 10. HDSL2 Loss Values Cable Cable Temperature Gauge Type 68°F 90°F 120°F 3.902 4.051 4.253 Pulp 4.030 4.179 4.381 2.863 2.957 3.083...
1. Verify that the channel bank or ONU BPS power LEDs are on. STAT 2. Verify that the equipment type for the Litespan H2TU-C slot is AHDSL2. Using TL1, the equipment type is shown with the command rtrv-eqpt::AID, where AID is the access identifier (i.e., cot-1-15).

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.
Loopback data from customer toward customer at H2TU-C Arm/11000 The H2TU-R loops up toward the network. No AIS or errors are sent as a result of this loopback. The H2TU-C arms. (also known as a 2-in-5 pattern) When sent from the customer, this code arms all modules.
Page 29
2. Modules must be armed with 11000b or FF48h for this code to function. 3. If NIU is enabled, then the H2TU-R can be in network loopback when the H2TU-C or H2R loop up codes are sent.

Litespan H2TU-C Provisioning Tutorial GENERAL This appendix describes the commands necessary to provision the Litespan H2TU-C. A more detailed explanation of shelf-specific items may be found in the Alcatel Practice for the Litespan Access Platform (OSP 363-405-000), Volume 6: TL1 Software Reference, and Volume 7: TL1 Messages (OSP 363-405-502).
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).
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.
A semicolon ends the string at any point if the remaining parameters are to be left unchanged or in their default states. 1. Determine if a cross-connect exists for the slot in which the H2TU-C is assigned by enter- ing the following command: RTRV-CRS-T1::<TERMINAL>-<BANK>-<SLOT>;...

Appendix B, Litespan H2TU-C Provisioning Tutorial - HDSL Provisioning NOTE The Litespan H2TU-C ships with a Line Code default of B8ZS; how- ever, the Litespan automatic default assignment changes the Line Code setting to AUTO when the Litespan H2TU-C is installed. To deliver HiCap service, this parameter should be returned to B8ZS.
