scrambling function on the CES Service Details Screen. Normal operation
will have Payload Scrambling enabled. (See Figure 4.34 on page 4-37.)
Partial Fill 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.
Rx Cell Delay Var Maximum cell arrival jitter in 10-
µ
s increments that the reassembly process
will tolerate in the cell stream without producing errors on the CBR service
interface. Default is 100 for a 1000-
µ
s Cell Delay Variation (CDV).
Cell Loss Int Time in milliseconds for the cell loss integration period. If cells are
continuously lost during the specified period of time, Cell Loss Status is set to
“Loss.” Default is 2500 ms.
Admin Status Sets the Administrative Status of the CES IWF. “Up” indicates traffic flow is
enabled, and “Down” indicates traffic flow is disabled across the CES IWF.
NOTICE: To enable a new parameter, rather than saving and restarting, set the
Administrative Status to “Down,” and click on the “Submit” button at
the bottom of the screen. Then set the Administrative Status to “Up,”
and click on the “Submit” button once again.
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.
Status
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.
Pointer Reframes Displays the number of events in which the AAL1 reassembler found a
Structured Data Pointer (SDT pointer) where it was not expected, making it
necessary to reacquire the pointer.
Pointer Parity Errs Displays the number of events in which the AAL1 reassembler has detected
an SDT pointer parity check failure.
AAL1 Seq Errs Displays the number of times the sequence number of an incoming AAL1
frame causes a transition from the “sync” state to the “out of sequence” state.
Lost Cells Displays the number of cells detected as lost in the network prior to reaching
the destination CES IWF AAL1 layer processing. As an example, the number
