Testing Commands

The H2TU-C testing commands are used to initiate and terminate loopbacks and disconnect for testing purposes. Table 8 lists and defines the TL1/Litecraft testing commands.

NOTE

Before entering loopbacks, the user needs to remove the card from service. This can be done with the RMV-HDSL command. The card can then be restored to service with the RST-HDSL command.

NOTE

When entering access identification (AID), the user needs to specify whether a loopback command is for a C or an R. For example, AID=RT-1-21-C.

Alarms

The selectable alarm threshold crossing alerts are as follows:

SNR margin threshold

HDSL2 and DS1 15-minute ES, SES, UAS thresholds

HDSL2 and DS1 daily ES, SES, UAS thresholds

HDSL2 loop attenuation threshold

DS1 15-minute CV-L, B8ZSS-L, and PDVS-L thresholds

DS1 daily CV-L, B8ZSS-L, and PDVS-L thresholds

The following additional alarm conditions are provided by the H2TU-C:

HDSL2 LOSW alarm

HDSL2 unit failure alarm

HDSL2 loop continuity alarms

HDSL2 circuit reset

DS1 LOS alarm

H2TU-R AIS, RAI, INCRAI-CI

Power Requirements

When deploying any Litespan H2TU-C, the power requirements for the application should also be considered for product mix calculations and maximum number of Litespan H2TU-Cs within a channel bank assembly. Use Worksheet PW-1 in the “Engineering and Planning” section of Alcatel practice, OSP TL1 Software Documentation, release

7.1or higher, to determine whether a particular

combination of channel units is within power-drain specifications.

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.
