Chapter 23: Configuring Frame Relay Interworking
Avidia System Configuration and Management User Manual 473
d In the Committed Burst box, type the committed burst value in data bits. The valid range
is 0 to 144000, with 0 as the default.
Committed Burst is the maximum number of data bits that the network will transfer
under normal conditions during the measurement interval.
e In the
Throughput box, type the throughput value in seconds. The valid range is 0 to
144000, with 0 as the default.
Throughput is the average number of data bits transferred per second across the
network interface in one direction.
7 In the
Interworking section, select the frame relay interworking standard (FRF.5 or FRF.8).
Frame relay interworking allows frames to be transported by an ATM network to an ATM
device or another frame relay device. There are two standards for interworking:
•
FRF.5 defines how frames are encapsulated so that they can be carried by the ATM
network to another frame device. If you select this option, proceed to Step 8.
• FRF.8 defines how frames are translated between ATM and frame devices. If you select
this option, skip to Step 9.
8 If you selected Interworking FRF.5, do the following:
a In the
Rx LP Mode box, select the Rx LP mode (1 or 2).
The Rx LP mode determines the loss priority settings when transmitting from ATM to
frame relay.
1—The frame relay header DE field is set if the CLP field of one or more ATM cells
of a frame is set to 1 or if the FR-SSCS PDU header DE field is set to 1.
2—The frame relay header DE field is copied into the FR-SSCS PDU header DE field,
independent of the ATM CLP field value received.
b In the
Tx LP Mode box, select the Tx LP Mode (1 or 2).
The Tx LP mode 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.
