Line Mode The protocol or protocols the port can use (Default =
DUAL):
ADSL – The port supports ADSL only.
REACH – The port supports ReachDSL only.
DUAL – The port supports both ADSL and ReachDSL.
ADSL will be used unless the line is too long or noisy to
support it.
Line Code The physical transport method (Default = Multimode):
Multimode – The line card adapts to the code the endpoint
is set for.
DMT – The line code is G.dmt (ITU 992.1). The endpoint
must be set to G.dmt.
G.Lite – The line code is G.lite (ITU 992.2). The endpoint
must be set to G.lite.
ANSI – The line code is ANSI T1.413, Issue 2. The
endpoint must be set to ANSI.
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.
