[-lpmode (1|2)]
The LP mode determines the content of the ATM CLP (Cell Loss Priority) field when
translating from frame relay to ATM.
1—The frame relay header DE (Discard Eligibility) field is mapped into the ATM CLP
field of every ATM cell generated by the segmentation process of the AAL5 (ATM
Adaptation Layer Type 5) PDU (Protocol Data Unit) 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.
[-lpvalue (0|1)]
The LP Value 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.
[-cimode (1|2)]
The CI Mode determines the content of the ATM EFCI (Explicit Forward Congestion
Indicator) field.
1—The frame relay FECN (Forward Explicit Congestion Notification) 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."
[-demode (1|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.
