PSD Limit Mask VDSL/ADSL power spectrum density limits are defined by the band plan. The various
standard bodies have defined a number of band plans that have regional significance.
The masks define shaping parameters for the signal, including Annex A or Annex B
RFI Bands Specifies the radio frequency interference bands to filter from the VDSL link.
To avoid interference it is necessary to introduce power control (notching) in one or more of
these bands.
Transport Protocol Used to specify the type of transport used when operating in VDSL mode. When running in
ATM mode, the VDSL interface can automatically toggle to ADSL if the modem at the
other end of the connection is ADSL. PTM (Packet Transport Mode) requires both ends of
the connection to be VDSL compliant
If the Transport Protocol is changed from ATM to PTM, there is a warning that VCs are not
supported, and any existing VCs will be removed from the port.
Max. # of Learned MAC
Addrs.
Depending on feature provisioning, the number of MAC addresses that can be learned (or
Off)
Power Management Changes the current power management state.
Power Mgmt Reentry
Delay
The amount of time that must elapse before re-entering the Low Power state after a transi-
tion to the Full On state. (Should not be set to a value less than 120 seconds)
Power Mgmt Trim The maximum aggregate transmit power reduction (trimming) that can be performed with
each power trim operation in the Low Power state.
Power Mgmt Trim Delay The amount of time that must elapse before an additional reduction (trimming) of power
occurs in the Low Power state.
Low Power Min Rate The minimum net data rate for the bearer channel while operating in the Low Power state.
The value for LOWPOWERRATE must be between MAXDOWNSTREAMRATE and
MINDOWNSTREAMRATE
Modify Enabled when a value in New Value field has been entered, modifies the attributes accord-
ing to the updated values.There is an error message if a value is invalid.
Clear Entry Fields Clear any fields that have been datafilled but not yet Modified
Enable Enabled if the port is in an Administrative State of DOWN, enables the port and so brings
the Administrative State to UP. If possible (for example, the VDSL2 card must be enabled),
the Operational State will change to UP.
Disable Enabled if the port is in an Administrative State of UP, disables the port and so brings the
Administrative State to DOWN. The Operational State will also change to DOWN.
Alarms Invokes the Alarm table of the Fault Management Object.
