For the Model 8355, the following ATM Traffic Profiles screen appears:
The traffic profiles initially displayed are predefined and cannot be altered.
Table 3-1, Traffic Profile Characteristics, shows their characteristics.
AUTOBAUD (Model 8335 only): This profile allows for packet traffic to the
endpoint that is used during training of the DSL link. It is also used to retrieve
statistics from the endpoint during normal operation. There is no PCR (Peak
Cell Rate) associated with the profile, since there is no policing.
IP MGT (Models 8335 and 8385 only): This profile is for a management path
to the endpoint that is used by the Network Access Provider to manage the
endpoint. This traffic could include SNMP or Telnet traffic. This connection is
not policed.
PACKET: This profile allows packet data traffic up to the maximum that the
DSL link can handle. There is no policing associated with this connection.
The priority mechanism will ensure that the voice traffic to be sent ahead of
the data traffic. This is the only default profile for the Model 8355.
