Payload
The 8300 Endpoint scrambles/descrambles cell payload bytes at the physical
layer interface using an x

scrambling function on the CES Service Details Screen. Normal operation will
have Payload Scrambling enabled. (See Figure 2-32. on page -35.)
Partial Cell Fill Byte
Sets the number of user octets per cell. Setting this parameter to 0 disables Partial
Cell Fill, and all cells are completely filled before being sent.

2500 ms.
Administrative
Sets the Administrative Status of the CES IWF. Up indicates traffic flow is enabled,

NOTICE:
Operational Status
Displays the Operational Status of the CES IWF. The state will be Down or
Unknown if the supporting CBR or ATM interface is down or unknown.

Reassembly Cells
Displays the number of cells received by the CES IWF. This number excludes cells
that have been discarded for any reason, including cells not used due to their
being misinserted or discarded while the reassembler was awaiting
synchronization.
Header Errors
Displays the number of AAL1 header errors detected, including those that have
been corrected. Header errors include correctable and uncorrectable CRCs and
bad parity.
