Frame Relay-to-ATM Service Interworking
• CLP is always 1.
In the ATM-to-Frame Relay direction, you can specify a CLP-to-DE mapping scheme for an
individual connection:
• If one or more ATM cells belonging to a frame has CLP=1, the DE field of the Frame Relay frame
is set.
• DE is always 0.
• DE is always 1.
Congestion Indication
This section describes congestion indictors. You can modify the CLP and congestion indicators for
individual connections. On the CLI, use the cnfchanmap command. In the Frame Relay-to-ATM
direction, you can configure a Frame Relay-to-ATM SIW connection for one of the following
Forward Explicit Congestion Notification (FECN)-to-Explicit Forward Congestion Indicator (EFCI)
schemes:
• FECN bit in the Frame Relay frame is mapped to the EFCI bit of every ATM cell generated by
the segmentation process of the frame.
• EFCI is always 0.
• EFCI is always 1.
In the ATM-to-Frame Relay direction, service interworking connections use the following EFCI to
FECN/BECN mapping schemes:
• If the EFCI bit in the last ATM cell of a segmented frame received is set to 1, the FECN of the
Frame Relay frame is set to 1.
• BECN is always set to 0.
