Configuring Frame Relay FRF.8 Circuits
214 Avidia System Configuration and Management User Manual
[-devalue (0|1)]
The DE value determines the content of the frame relay DE field when the DE mode is set
to 2.
0—The network cannot discard frames.
1—The network can discard frames.
[-CIR <value>]
The committed information rate (circuit throughput) in seconds. The valid range is 0 to
144000, with 0 as the default.
[-Be <value>]
The excess burst is the maximum number of uncommitted data bits that the network will
attempt to deliver. The valid range is 0 to 144000, with 144000 as the default.
[-Bc <value>]
Committed burst is the maximum number of data bits that the network agrees to transfer
under normal conditions during the measurement interval. The valid range is 0 to 144000,
with 0 as the default.
[-type (ubr|cbr|nrt-vbr|rt-vbr)]
The type determines the traffic class.
ubr (Unspecified Bit Rate)—This is a best-effort class of traffic that is best suited for
LAN. When network congestion occurs, the data is stored in a buffer until it can be sent.
cbr (Constant Bit Rate)—This traffic class carries a guaranteed constant bandwidth. It is
best suited for applications that require fixed bandwidth, such as uncompressed voice,
video, and circuit emulation. CBR is a Quality of Service class defined by the ATM Forum
for ATM network.
nrt-vbr (non-real-time Variable Bit Rate)—This traffic class carries variable bandwidth.
It is well suited for data services such as frame relay over ATM which requires guaranteed
bandwidth and lower Quality of Service. It is not well suited for LAN traffic due to the
unpredictability of LAN traffic burst size.
rt-vbr (real-time Variable Bit Rate)—This traffic class carries a variable bandwidth. It
is well suited for real-time services such as compressed voice and video which require
stringent cell transfer latency and less bursty traffic. It is not well suited for LAN traffic due
to the unpredictability of LAN traffic burst size.
