Field Action/Description
Clock Mode Select the service clocking mode from the pull-down menu. For
structured mode this field must be set to Synchronous. For
unstructured mode, the field can be set to Synchronous, SRTS, or
Adaptive.
Max Buffer Size
(1-65535)
Specify the maximum number of bytes in the reassembly buffer.
The default is 128. By configuring a smaller size, you provide
more buffers to reassemble packets and, thus, improve reception.
However, the maximum buffer size must be large enough to hold
the largest packet of information. Packets are discarded if the
reassembly buffer is full.
Cell Loss
Integration Period
(msec)
(1000-65535)
The cell loss integration period in milliseconds. The default value
is 2500.
Insert Cell Type Select the cell type to be inserted when there is cell loss. The
options are:
FF — (default) The value of the cells inserted is the hexadecimal
FF.
Previous Cell — The value of the cells inserted are from the
previous cell.
User Defined — The value of the cells inserted is defined by the
user. If the user selects this option, the value in Insert Field Cell
can be from zero (0) to 255.
Random User — The value of the cells inserted is a random
value.
Enable Partial Cell
Fill
Select the check box to enable partial cell fill, that is, cell fill for
only used timeslots. This is a time saving condition in that when
partial cell fill is enabled the switch does not have to cycle
through unused time slots.
LPort Trunk Conditioning —
Rx Conditioning
Data (0-14)
The user supplied data when the data is conditioned in the receive
direction (egress or local port).
For more information on Trunk Conditioning including range of
values and defaults, see Appendix I, “About Trunk
Conditioning.”
