Back to Back
The Back to Back is used to test the port by connecting two MultiFRADs
together without a frame relay network in between them. Back-to-back
mode still requires the use of DSU/CSUs, but they should not be connected
over the frame relay network. The options are On and Off with a default of
Off.
Back-to-back mode is useful when two MultiFRADs are at the same location
and they are connected via DSUs for testing. Back-to-back mode can also
be used to connect two MultiFRADs over a private leased line.
Excess Burst Rate (Be)
The Excess Burst Rate (Be) defines the maximum allowable data transfer
rate the MultiFRAD can exceed the Committed Info Rate (CIR) during a time
interval. The Be is the maximum additional data rate at which the MultiFRAD
can present to the network during a time interval. The default Be is 24K.
