Philips CPWBS154 manual Following items are included on the Adsl status, Fast Path FEC Correction

ENGLISH 29

	The following items are included on the ADSL status page:
Parameter	Description
Status
• Line Status	Shows the current status of the ADSL line connection.
• Link Type	Two types of link: Fast path and Interleaved path.
Data Rate
• Upstream	Maximum upstream data rate.
• Downstream	Maximum downstream data rate.
Operation Data/
Defect Indication
• Noise Margin	Maximum upstream and downstream noise margin.
• Attenuation	Maximum reduction in the strength of the upstream and downstream signal.
• Fast Path FEC
Correction	There are two latency paths that may be used: fast and interleaved. For
	either path, a forward error correction (FEC) scheme is employed to ensure
	higher data integrity. For maximum noise immunity, an interleaver may be
	used to supplement FEC.
• Interleaved Path FEC	An interleaver is basically a buffer used to introduce a delay, allowing for
Correction	additional error correction techniques to handle noise. Interleaving slows
	the data flow and may not be optimal for real-time signals such as video
	transmission.
Fast Path CRC Error	The number of Fast Path Cyclic Redundancy Check errors.
Interleaved Path CRC
Error	The number of Interleaved Path Cyclic Redundancy Check errors.
Loss of Signal Defect	Momentary signal discontinuities.
Fast Path HEC Error	Fast Path Header Error Concealment errors.
Interleaved Path HEC
Error	Interleaved Path Header Error Concealment errors.
Statistics	(Superframes represent the highest level of data presentation. Each
	superframe contains regular ADSL frames, one of which is used to provide
	superframe synchronization, identifying the start of a superframe. Some of
	the remaining frames are also used for special functions.)
• Received cells	Number of cells received.
• Transmitted cells	Number of cells transmitted.
