CAUTION

Prior to installing or removing the Litespan H2TU-C, observe the following warning: If the Litespan H2TU-C is removed from a line card slot, wait at least 15 seconds before reinsertion. If connected to the MTI craft interface terminal, wait until the message “AID:MJ,UEQ.” appears (where “AID” is the access identifier). This informs the Litespan common control assembly that the H2TU-C has been removed from its slot, after which the common control assembly begins looking for the reinsertion of the line card. Reinsertion any earlier than this may temporarily lock the H2TU-C into a nonfunctional state because the common control assembly will not send the AHDSL2 equipment type code to the H2TU-C line card.

Compliance

This product is intended for installation in restricted access locations only and in equipment with a Type “B” or “E” enclosure.

WARNING

Up to –200 VDC may be present on telecommunications wiring. The DSX-1 interface is intended for connection to intra-building wiring only. Ensure chassis ground is properly connected.

This product provides span powering voltage (negative only with respect to ground, –190 VDC nominal, GFI protection < 5 mA) and meets all requirements of Bellcore GR-1089-CORE (Class A2) and ANSI T1.418-2002. This product is NRTL listed to the applicable UL standards.

Provisioning

Provisioning of the H2TU-C is through the craft interface on the Maintenance and Test Interface (MTI) card either via TL1 commands or the Litecraft Pro Graphical User Interface (GUI). Refer to the Litecraft Pro Access Configuration Guide

(P/N 61221002L1-31) for detailed GUI information.

The provisioning and performance monitoring VT100 terminal screens may be viewed from the H2TU-R DB-9 RS-232 craft interface port. However, the provisioning options may not be changed or manipulated in any way from the H2TU-R.

NOTE

Please reference Alcatel document TL1 Software Reference, OSP 363-405-502 for detailed information regarding provisioning through the MTI craft interface.

The H2TU-C TL1/Litecraft commands are grouped as follows:

•Administration

•Cross-Connect Provisioning

•Maintenance

•HDSL Provisioning

•T1 Provisioning

•Testing

Administration Commands

Administration commands are used to remove or restore the H2TU-C to service, place equipment and facilities In-Service (IS) and Out-of-Service (OOS), and display system inventory. These commands are listed and defined in Table 3.

Cross-Connect Provisioning Commands

Cross-connect Provisioning commands are used to manage cross-connections. These commands are listed and defined in Table 4.

Maintenance Commands

Maintenance commands are use to clear and retrieve Performance Monitoring (PM) information and to display alarm Statistics. Table 5 lists and defines the available

TL1/Litecraft Maintenance commands.

AHDSL2 specifications

ADTRAN AHDSL2 is a sophisticated technology designed to enhance broadband connectivity, primarily focusing on delivering high-speed internet access through existing copper telephone lines. This solution is integral in supporting various applications, including voice, video, and data transmission, making it a versatile choice for service providers looking to upgrade their networks.

One of the key features of ADTRAN AHDSL2 is its ability to support asymmetric digital subscriber line (ADSL) technology, which allows for faster download speeds compared to upload speeds. This asymmetry is particularly beneficial for typical internet usage patterns where users often download more data than they upload. AHDSL2 can provide download speeds of up to 24 Mbps and upload speeds around 1 to 3 Mbps, depending on the line conditions and distance from the central office.

ADTRAN's AHDSL2 technology incorporates advanced capabilities such as auto-negotiation and improved line diagnostics. These features enable service providers to automatically adjust the settings for optimal performance based on the quality of the copper line. Furthermore, the built-in diagnostics tools help in the identification and troubleshooting of potential issues, reducing time and resources spent on maintenance and support.

The technology also supports the ITU G.992.3 and G.992.5 standards, which enhance the reach and efficiency of DSL services. It offers better performance in high-noise environments and allows for longer distances between the end-user and the central office, thus expanding the coverage area for broadband services.

Another significant aspect of ADTRAN AHDSL2 is its ability to operate over a range of frequencies, which minimizes interference from other services. By using frequency division multiplexing, the technology ensures that voice and data can be transmitted simultaneously without degradation of service quality.

ADTRAN AHDSL2 is also designed with scalability in mind, making it suitable for various deployment scenarios, whether in residential or commercial settings. Service providers can easily integrate this technology into their existing networks, ensuring a seamless upgrade path as customer demands for bandwidth continue to rise.

Overall, ADTRAN AHDSL2 stands out as a reliable and efficient solution for enhancing broadband services over copper infrastructure, with features that cater to both service provider needs and end-user demands for high-speed internet access. Its combination of advanced technology and easy integration makes it a compelling choice for operators looking to improve their service offerings.
