Chapter23: Configuring Frame Relay Interworking
Avidia System Configuration and Management User Manual 481
FRF.5 Tx LP Mode The Tx LP Mode, which determines the content of the
FR-SSCS PDU header DE and ATM cell ATM CLP
fields.
1—The frame header DE field is copied in the
FR-SSCS PDU header DE field and mapped into the
ATM CLP field of every ATM cell generated by the
frame.
2—The frame header DE field is copied into the
FR-SSCS PDU header DE field. 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 CLP Mask value.
FRF.5 CLP Mask The CLP Mask setting, which 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.
FRF.8 LP Mode The LP Mode, which 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.
FRF.8 LP Value The LP Value, which determines the content of the
ATM cell CLP field when the LP mode is set to 2.
0—The network cannot discard cells.
1—The network can discard cells.
FRF.8 CI Mode The CI Mode, which determ ines 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 n ot
experienced."
