24-6 ADSL Commands
Down/up stream
Depth value
This is the current downstream or upstream, interleaved codeword depth value. The larger
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
Transceiver
Output Power
The total output power of the transceiver varies with the length and line quality. The farther
away the subscriber’s ADSL modem or router is or the more interference there is on the
line, the higher the power will be.
Current ATUR
Information
This section contains data acquired from the ATUR (ADSL Termination Unit – Remote)
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.
24.3.8 Lineperf 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.
Figure 24-3 Lineperf Command Example
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).
