ADSL2 DELT Test

DELT is primarily used for reactive tests on a loop after a CPE has been deployed, either to help troubleshoot a line or to capture a baseline of loop characteristics at the time of installation. DELT can determine the ADSL2+ data rate (up/down), loop attenuation (up/down), SNR (up/down), and noise (up/down).

Description

Port selection menu	Please select a port to perform DELT.

Operation State	This object identifies the high level operational state for the ATU.
	Here is the state flow:
	data (Click START) > handshake > discovery > delt Training > delt (Diagram is
	displayed) ->handshake -> discovery > Training > data

ATUC Attainable net data rate	Indicates the maximum currently attainable data rate by the ATU. This value will be
	equal to, or greater than the current line rate. (Downstream)

ATUR Attainable net data rate	Indicates the maximum currently attainable data rate by the ATU. This value will be
	equal to, or greater than the current line rate. (upstream)

Upstream HLIN	The DELT-related parameter that provides an array of complex downstream Hlin (f)
	values in linear scale. (Not available for ADSL and ADSL2plus)

Upstream HLOG	The DELT-related parameter that provides an array of real downstream Hlog (f) values
	in dB. (Not available for ADSL and ADSL2plus)

Upstream QLN	The DELT-related parameter that provides an array of real downstream QLN (f) values
	in dB. (Not available for ADSL and ADSL2plus)

Downstream HLIN	The DELT-related parameter that provides an array of complex upstream Hlin (f) values
	in linear scale. (Not available for ADSL and ADSL2plus)

Downstream HLOG	The DELT-related parameter that provides an array of real upstream Hlog (f) values in
	dB. (Not available for ADSL and ADSL2plus)

Downstream QLN	The DELT-related parameter that provides an array of real upstream QLN (f) values in
	dB. (Not available for ADSL and ADSL2plus)
