Spectrum Manager ADSL Protect

The Spectrum Manager software makes EtherLoop spectrally compatible with asymmetrical services such as ADSL and G.Lite, detecting and protecting against interference within the same binder. In addition, EtherLoop in its native state is spectrally compatible with symmetrical digital services such as T1, HDSL, HDSL2, or SDSL.

Spectrum Manager operates under five modes of operation:

Mode	Description
Native	EtherLoop operates without the analysis of other service activ-
	ity in the individual loops.
Monitor	Spectrum Manager analyzes other services in the loop that
	may limit EtherLoop performance.
Forced	EtherLoop provides optimum spectrally compatible perfor-
	mance with asymmetric services in the individual loop that
	may temporarily affect EtherLoop’s upstream capability. In this
	mode, EtherLoop is forced to “mimic” asymmetric DSL.
Auto-Protect	EtherLoop operates in an Asymmetric Mode if asymmetric
	interferers are present. EtherLoop returns to normal upstream
	operations once the interference is gone.
Video Protect	EtherLoop operates in a forced Asymmetric Mode with guaran-
	teed high downstream bandwidth for the delivery of streaming
	video applications.

Spectrum Manager-Video Protect

The Spectrum Manager-Video Protect activates the EtherLoop asymmetrical operation with all upstream traffic limited to a training speed of 25 (3 Mbps) on the BitStorm 10306 CO modems. Downstream traffic continues to run as fast as the loop conditions allow. When this feature is enabled, all nearby EtherLoop lines running high-speed video downstreams are protected. All CO modems at a site are required to have the feature enabled by StormTracker Site Manager or EMS via the MIU SNMP agent.
