[dpboescma <escma>]
[dpboescmb <escmb>]
[dpboescmc <escmc>]
= These parameters define a cable model that is used
to describe the frequency dependent loss of
exchange-side cables.
<escma>: DPBO A parameter, 0~640 represent -
1~1.5 in step of 1/256
<escmb>: DPBO B parameter, 0~640 represent -
1~1.5 in step of 1/256
<escmc>: DPBO C parameter, 0~640 represent -
1~1.5 in step of 1/256
[dpboesel <esel>]
= Specify the electrical length of the cable between the
system and CPE devices.
<esel>: Electrical length of DPBO, 0~511 (in units of
0.5dB)
See Section 10.2.9 on page 212.
[dpbomus <mus>]
= Set the assumed minimum usable received PSD mask
(in dBm/Hz) for exchange based services, used to
modify parameter DPBOFMAX defined below. Enter
from 0 to 255 to set the PSD to 0~-127.5 dBm/Hz in
steps of -0.5 dBm.
[dpbofmax <fmax>]
= This defines the maximum frequency at which DPBO
may be applied.
<fmax>: 32~6956 (units of 4.3125kHz)
[dpbofmin <fmin>]]
= This defines the minimum frequency from which the
DPBO shall be applied.
<fmin>: 0~2048 (units of 4.3125kHz)
[dpboepsd <tone> <epsd>
[...]|<psdid>]
= DPBOEPSD (Assumed Exchange PSD Mask) defines
the PSD mask that is assumed to be exchanged at
CO. Use this graph to view PSD level to frequency
relationship. The horizontal is frequency in MHz and
vertical is power level in dBm/Hz.
<epsd>: 0~255 (scalar value 0~-127.5dBm in steps
of -0.5dBm)
<psdid>: standard psd shape id for psd toolbox
0: psd_co, 1: psd_flat, 2: psd_cab_ansi, 3:
psd_cab_etsi, 4: psd_exch_etsi, 5: psd_exch_ansi
[upbokl <esel>]
= Sets the electrical length of the cable between
system and cabinet 0~511 in units of 0.5dB.
[upboklf
<disable|auto|override>]
= UPBO (Upstream Power Back-Off) mitigates far-end
crosstalk (FEXT) caused by upstream transmission on
shorter loops to longer loops.
disable: turns UPBO off.
auto: enables UPBO and CPE devices’ PSD
adjustment based on the negotiation result with the
Switch.
override: forces CPE devices to use the electrical
length defined by the system (for the UPBOKL setting
above) to compute their UPBO.
[upbopsda <us1a~us4a>]
= Specifies parameter A value(s) for each upstream
band. The parameter A defines the original band
shape.
<us1a~us4a>: 4000~8095, in steps of 0.01 dBm/Hz.
