C559:2012 defines the performance requirements for DSL and other technologies on copper access networks. The Code offers a coordinated approach to reduce the risk of interference between services deployed over access networks.
ACIF first published the Unconditioned Local Loop Service (ULLS) Network Deployment Rules Industry Code in August 2001. On the advice of the Network Reference Panel, the ACIF executive made some corrections in March 2002 to Part 3 of this Industry Code for clarity of and consistency between the definitions of Deployment Classes.
The Code was revised in 2003 to include in the Code the facility for use of a modified Crosstalk Calculation Template where a Non-deployment Class System is obtained by a linear filtering of the transmit PSD of a Deployment Class System, without any change to the line code plus some agreed changes to Benchmarks based on industry experience.
The Code was revised in 2005 to include Deployment Classes based on ADSL2, ADSL2+ and ESHDSL.
The Code was revised in 2006 to include Deployment Classes based on ADSL2 and ADSL2+ with extended upstream bandwidth.
The Code was revised in 2011-12 to include current cable types and some relatively minor updates to cable loss values to reflect industry experience.
This Code was registered by the ACMA on 16 May 2012.
The Code was reconfirmed in 2018 and the next review is scheduled to occur in 2023.
Non-Deployment Class Systems
There is also a list of Non-Deployment Class Systems that may be of interest to anyone using C559:2012.
- Refer to C559:2012 for information on what is a Non-Deployment Class System.
- Refer to G618:2004 Approval of Non-Deployment Class Systems Industry Guideline for information on the process to propose a Non-Deployment Class System.
The October 2011 version of the Spectral Compatibility Software Tool is available from us. Please contact us if you would like the Tool to be emailed to you. You will be sent a zip file (.zip, 2.7MB) which consists of a license agreement, a user manual and the Tool (.xls format, 16MB). The Tool can be used for the calculation of the crosstalk scenarios in C559:2012.
C569:2015 Unconditioned Local Loop Service - Ordering, Provisioning and Customer Transfer
This Code provides a carrier/CSP operational framework for the ordering and provisioning of the unconditioned local loop pairs and the transfer of customers between CSPs.
The Code was updated in 2015 to:
- remove reference to provisioning activity during the cooling off period in the definition of ‘Invalid ULLS Transfer’ as this is prohibited by the Australian Consumer Law;
- remove rules on Information to be Provided to Customers, with the intent being captured in the Customer Authorisation Industry Guideline (G651:2015);
- remove Appendix B: Customer Authorisation Minimum Requirements – ULLS Transfer, with the intent being captured in the Customer Authorisation Industry Guideline (G651:2015); and
- reflect its publication as a Communications Alliance document.
The Code was reconfirmed in 2021 and the next review is scheduled to occur in 2026.
