• 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
