Dynamic line management

Dynamic line management is a capability provided by the Alcatel-Lucent 5530 NA, which greatly improves DSL line stability. With real-time services such as voice and video, line stability has become paramount. To enforce line stability, the Alcatel-Lucent 5530 NA monitors key DSL line parameters and triggers line profile re-configuration, according to pre-defined line profile transitions. This process enables you to fine-tune parameters such as line speed, interleave mode and power spectral density until the line reaches the set quality and stability objectives. The effective reconfiguration of the line is normally executed by your service provisioning OSS upon recommendation of the Alcatel-Lucent 5530 NA, but other implementation options may let the Alcatel-Lucent 5530 NA perform the line reconfiguration by itself.
