Option
Description
3. Fragmentation
For links connecting to other Integration units. This
is for a DLCI which will be connected to another
DLCI (within the unit) with frame relay access
devices (FRADs) attached. This option reduces the
frame size across the link, thus reducing delays and
maintaining voice quality. (Refer to Pass-Through
Applications on page 4-33.)
Note:
With fragmentation, you cannot configure
the frame size. The unit will fragment
automatically.
Note:
To change a configured Level 2 Protocol, delete the DLCI, add the DLCI, and
then set the new protocol.
DLCI Parameters
Once you have configured a DLCI you will need to configure the DLCI
parameters:

COMMITTED BURST SIZE FORWARD (BC.FWD)
2.
COMMITTED BURST SIZE BACKWARD (BC.BWD)

EXCESS BURST SIZE FORWARD (BE.FWD)

EXCESS BURST SIZE BACKWARD (BE.BWD)

D
Committed burst size: (Bc) The maximum amount of data, in bits, that
a network agrees to transfer under normal conditions. Data may or
may not be contiguous.
D
Excess burst size: (Be) The maximum amount of uncommitted data, in
bits, that the network will attempt to deliver. Data may or may not be
contiguous.
D
CIR, Committed Information Rate: Similar to data rate, the
predictable level of service for the DLCI. If you are using voice in your
network, do not select a rate lower that 16 Kbps unless you are using
zero CIR.
