Table 3-1. Fields in the DSLPipe status window (Continued)

Fields	Description
V35	Indicates OFF_line or ON_line
Data Bit Polarity	Indicates Norm (Normal) or Rev (Reverse). The default is
	Rev.This means that the transmitter inverts the data polarity
	before sending data.
Sign/Magn Bit Seq	Indicates Norm (Normal) or Rev (Reverse). The default is
	Rev. This means that the magnitude bit is followed by the sign
	bit.
Noise Margin	Shows the noise margin value (in dB). If the noise margin is
	less than -5dB, the SDSL line is terminated.
Data Rate	Shows the current transmission rate
DSL ch Data	Shows one of the following: NRZ, NRZI, FMO, FM1, or
Encode/Decode	Manchester. The default is NRZ. This means that signal
	transmissions go from positive to negative without ever
	assuming a zero value (Non-Return to Zero).
V.35 ch Data	Shows one of the following: NRZ, NRZI, FMO, FM1, or
Encode/Decode	Manchester. The default is NRZ. This means that signal
	transmissions go from positive to negative without ever
	assuming a zero value (Non-Return to Zero).
DSL ch Rx CRC	Shows either Enable or Disable. The default is Enable.
	This means that the receiver will check for CRC over the SDSL
	line.
DSL ch Tx CRC	Shows either Enable or Disable. The default is Enable.
	This means that the CRC is appended to the end of the frame
	when data is sent over the SDSL line.
V.35 ch Rx CRC	Shows either Enable or Disable. The default is Enable.
	This means that the receiver will check for CRC over the V.35
	line.
