EWL (Equivalent
Working Length)
The estimated length of the line in kilofeet. This value is
usually specified by the carrier. This option is available only
if Spectrum Management is set to Enable on the Spectrum
Management screen (menu selection
A-A-G
) and the
equivalent working length parameter is specified in the
device’s factory initialization file.
EWL = L26 + 3(L24)/4, where L26 is the total length of the
26-gauge cable in the loop excluding any bridged tap and
L24 is the total length of 19, 22, or 24-gauge cable in the
loop excluding any bridged tap.
8.5 – 14.5 kft
in .5 kft increments, or
>14.5 kft
(Default = 10 kft).
Loop Length
The relative loop length of the line. This value is used to
limit transmit rates and maximum transmit power settings
according to local spectrum management guidelines, and is
usually specified by the carrier. This option is available only
if Spectrum Management is set to Enable on the Spectrum
Management screen (menu selection
A-A-G
), and if
relative loop length is specified in the device’s factory
initialization file.
Short
Medium
Long
Quad
The quad cable configuration. This value is used to limit
transmit rates and maximum transmit power settings
according to local spectrum management guidelines, and is
usually specified by the carrier. This option is available only
if Spectrum Management is set to Enable on the Spectrum
Management screen (menu selection
A-A-G
), and if the
quad cable configuration is specified in the device’s factory
initialization file.

POTS Detection
Voltage
The voltage used to detect the presence of Plain Old
Telephone Service (POTS) on the DSL line:
0 – 74 volts
in 1 volt increments, or
D
for Disable
(Default = 3 volts).
Maximum Tx Power
ATU-C/ATU-R
The maximum transmission power settings for the ADSL
Transmission Unit
– Central Office (ATU-C) and ADSL
Transmission Unit – Remote Site (ATU-R). The range may
be limited according to local guidelines when Spectrum
Management is set to Enable on the Spectrum
Management screen (menu selection
A-A-G
):
+12dB – -14dB
in 1 dB increments (Default = +12dB)
