VDSL Configuration

Physical Interfaces Information

-Serial Number – A number given by the manufacturer to the item produced. This only displays on the CPE side.

-Vendor ID – The name of the manufacturer of this switch.

-Version Number – The number of the current hardware.

-Current Signal to Noise Ratio Margin – To ensure a stable link, you should add a margin to the theoretical minimum Signal-to-noise ratio (SNR). For details see “VDSL Port Configuration” on page 3-58.

Range: 0-9 dBm Default: 0 dBm

-Current Attenuation – The attenuation of the signal. Units: db

-Current Status – This displays defects in the VDSL line. In the current version, this always displays 0, which means no defects.

-Current Output Power – The total output power transmitted on this line. Units: 0.1 dBm

-Current Attainable Rate – The maximum line data rate using the current profile.

Unit: Bits per second

-Current Line Rate – The current line data rate. Unit: Bits per second

Channel Interface Information

-Interleave Delay – Transmission delay caused by the use of interleaving. Units: Milliseconds

-CRC Block Length – Cyclic Redundancy Code (CRC) is a number derived from, and transmitted with, data frames in order to detect corruption of data.

-Current Transmit Rate* – The current rate of data transmission.

-Current Transmit Slow Burst Protect* – Actual level of impulse noise (burst) protection for an interleaved (slow) channel. This parameter is not applicable to fast channels. For fast channels, a value of zero is returned.

-Current Transmit Fast Forward Error Correction* – Actual Forward Error Correction (FEC) redundancy related overhead for a fast channel. This parameter is not applicable to an interleaved (slow) channel. For interleaved channels, a value of zero is returned.

* Not supported in the current version
