c

In the

CLP Mask

box, select the mask used when

Tx LP Mode

is set to

2

(

0

or

1

).

The CLP Mask determines the content of the ATM cell CLP field when

Tx LP Mode

is

set to

2

.

0

—The network cannot discard cells.

1

—The network can discard cells.

If you selected Interworking

FRF.8

, do the following:

a

In the

LP Mode

box, select the

LP Mode

(

1

or

2

).

The LP Mode determines the content of the ATM CLP field when translating from
frame relay to ATM.

1

—The frame relay header DE field is mapped into the ATM CLP field of every ATM

cell generated by the segmentation process of the AAL5 PDU containing the
information for that frame.

2

—The ATM CLP field of every ATM cell generated by the segmentation process of

the AAL5 PDU containing the information of that frame is set to the

LP Value

.

b

In the

LP Value

box, select the value used when

LP Mode

is set to

2

(

0

or

1

).

The LP Value determines the content of the ATM cell CLP field when

LP Mode

is set

to

2

.

0

—The network cannot discard cells.

1

—The network can discard cells.

c

In the

CI Mode

box, select the

CI Mode

(

1

or

2

).

The CI Mode determines the content of the ATM EFCI field.

1

—The frame relay FECN field is mapped to the ATM EFCI field of every ATM cell

generated by the segmentation process of the AAL5 PDU containing the information
of that frame. This mode provides congestion indication to the end points, where
higher-level protocol entries might be involved in traffic control mechanisms.

2

—The ATM EFCI field is set to "congestion not experienced."

d

In the

DE Mode

box, select the

DE Mode

(

1

or

2

).

The DE Mode determines the content of the frame relay DE field when transmitting
from ATM to frame relay.

1

—If the ATM CLP field of one or more cells belonging to a frame is set, the frame

relay DE field is set.

2

—If the ATM CLP field of one or more cells belonging to a frame is set, the frame

relay DE field is set to the

DE Value

.
