Notes: 1.
The actual data rates may be less than those shown in the table
depending on the protocols/applications used.
2.
If the “LL” type profile is selected, the error rate due to noise
in transmission, is increased, but the signal latency is reduced.
3.
The “Public” profiles conform to specific standards such as
ANSI or ETSI. The “Private” profiles do not conform to these
standards.
4.
Profiles “user-1” and “user-2” are user-configured profiles.
The values shown for the downstream and upstream rates are
the default values. These rates may be configured to values
between 1 Mbps and 15 Mbps. (See “Configuring a
User-specified EFM Profile” on page 2-101.)
Fields and Attributes
•
Profile Name –
The name for the specific set of communication
parameters.
•
Profile Type –
“Public” profiles are those that meet specific standards
e.g., ETSI or ANSI. “Private” profiles do not meet these standards.
The ports on a VDSL switch can be assigned the same or different
private profiles. If a public profile is configured on the switch and you
want the switch VDSL ports to use private profiles, you must first
disable the public profile by using the
no efm profile global
configuration command.
•
Downstream Rate –
Rate of data transmission from the switch to the
CPE.
•
Upstream Rate –
Rate of data transmission from the CPE to the
switch.
