32.3.1 Service Categories
Service categories ensure that high priority transmissions get the bandwidth they need.
CBR (Constant Bit Rate) provides a fixed amount of bandwidth that is always available even
if no data is being sent. A PCR is specified and if traffic exceeds this rate, cells may be
dropped. An example application is a T1 circuit.
rt-VBR (real-time Variable Bit Rate) also provides a fixed amount of bandwidth (a PCR is
specified) but is only available when data is being sent. An example application is real-time
videoconferencing.
profile
actv
This command sends the current selected profile
to BME (VDSL modem). It downloads modem
code into BME and also sends system and port
provisioning data to BME.
BME then starts a linkup attempt with the VDSL
line.
The command will have no effect if the current
used profile has the same settings as the current
running profile settings.
default
Reset profile setting to factory defaults.

default profile.
