IES-1000 User’s Guide

Down/up stream	This is the current downstream or upstream, interleaved codeword depth value. The larger
Depth value	the number, the more interleave blocks data is distributed across and the stronger the
	protection against errors (and the lower the performance is). The smaller the number, the
	fewer interleave blocks data is distributed across and the higher the performance (and the
	weaker the protection against errors).
Total	The total output power of the transceiver varies with the length and line quality. The farther
Transceiver	away the subscriber’s ADSL modem or router is or the more interference there is on the
Output Power	line, the higher the power will be.
Current ATUR	This section contains data acquired from the ATUR (ADSL Termination Unit – Remote)
Information	during negotiation/provisioning message interchanges. This information can help in
	identifying the subscriber’s ADSL modem or router. Information obtained prior to training to
	steady state transition will not be valid or will be old information.
Country Code	The country code is from the Vendor ID (g.994.1).
Provider Code	The provider code includes the Vendor ID and Version Number obtained from Vendor ID
	fields (g.994.1) or R-MSGS1(T1.413).
Capabilities	The “Capabilities” section displays what kind of DSL connection the subscriber’s ADSL
	modem or router supports.

24.3.8Lineperf Command

Syntax:

192.168.1.1 adsl> lineperf <port number>

where

<port number> = A port number, from 1 to 8.

The lineperf command shows the line performance counters of an ADSL port.

An example is shown next.

These counters display line performance data that has been accumulated since the system started. In the list above the definitions of near end/far end will always be relative to the ATU-C (ADSL Termination Unit-Central Office).
