Configuration Options

Table A-1. Network Interface Options (2 of 3)

Excessive Error Rate Threshold

Possible Settings: 1E–4, 1E–5, 1E–6, 1E–7, 1E–8, 1E–9

Default Setting: 1E–6

Determines the error rate at which an excessive error rate (EER) condition is recognized. The rate is the ratio of the number of CRC errors to the number of bits received in a certain period.

AutoRate

Possible Settings: Enable, Disable

Default Setting: Disable

Determines whether the unit automatically adjusts to the best line rate for conditions, or is fixed at the rate in the DSL Line Rate field. The automatically set rate cannot exceed Max DSL AutoRate.

HAutoRate is only available when the unit is configured as an LTU.

Enable – The LTU adjusts to the best line rate.

Disable – The LTU’s line rate is the DSL Line Rate selected.

DSL Line Rate

Possible Settings (Models 8747, 8777): 144, 272, 400, 528, 784, 1040, 1552

Default Setting: 1552

Possible Settings (Model 8779): 144, 272, 400, 528, 784, 1040, 1552, 2064

Default Setting: 2064

Determines the fixed line rate of the LTU when AutoRate is disabled. See Tables A-2 and A-3 for information about maximum payload rates for different DSL line rates.

HDSL Line Rate is only available when the unit is configured as an LTU and AutoRate is disabled.

144 to 2064 – The fixed DSL Line Rate, in kbps.

Max DSL AutoRate

Possible Settings (Models 8747, 8777): 144, 272, 400, 528, 784, 1040, 1552

Default Setting: 1552

Possible Settings (Model 8779): 144, 272, 400, 528, 784, 1040, 1552, 2064

Default Setting: 2064

Determines the maximum rate the unit can AutoRate to. See Tables A-2 and A-3 for information about maximum payload rates for different DSL line rates.

HMax DSL AutoRate is only available when the unit is configured as an LTU and AutoRate is enabled.

144 to 2064 – The AutoRate ceiling, in kbps.

EIA-530 Payload Rate

Possible Settings: 64, 128

Default Setting: 128

Specifies the synchronous port speed of the remote NTU if the NTU is an EIA-530 model and the DSL line rate is 144 kbps. At higher line rates the EIA-530 NTU runs at the highest payload rate possible.

HEIA-530 Payload Rate is only available when the unit is configured as an LTU.

64 or 128 – The synchronous port speed of the remote NTU, in kbps.
