for cell traffic. Configuring this setting incorrectly for a
particular circuit will cause poor performance at the ATM Layer.

OSET
Header Error Control is located in the last (5th) byte of the ATM cell header that checks for cell integrity
only. The Coset polynomial is applied to the received HEC for comparison with the HEC generated
internally. HEC errors may be detected after synchronization, and any detected bit errors prompt that the
cell be dropped. The choice are
E
NABLED
(def) or
D
ISABLED
.

NTERFACE
The T1 Sub-Interface is
ATM [0.0]
that represents the T1 physical and logical ports respectively. This is a
read-only field.

ONFIG
> VPI
ATM Virtual Path Identifier located in the ATM cell header identifies the virtual path over which this port
is running. The range is
0-256
. The default is
0
.
The setting must match the configuration setting of the ATM switch or DSLAM at the other
end of the circuit.
To insert a new PVC, press the
I
key when over the
N
UM
column. A new inserted PVC will
always be set up with the default parameters. To copy parameters from an old PVC to the
new PVC, use the copy (
C
) and paste (
P
) keys. Entire configuration trees can be copied
with this method.
To delete an unused PVC, use the
D
key when the cursor is over the number in the
N
UM
column. Once deleted, the PVC is gone permanently.
