Table 6-32. CES User Statistics Parameters
Parameter Description Possible Values
Sequence errors Number of times that the sequence number of
an incoming AAL1 SAR-PDU cell causes a
transition from the Sync state to the Out of Sync
state, according to the Fast-SN algorithm
(according to ITU I.361.1 Section III.2.4.2) Numerical
CES header errors Number of AAL1 header errors, including
corrected ones. Cells with a header error are cells
that have an erroneous Sequence Number Parity
(SNP) value. Numerical
Buffer underflow Number of times the CDVT buffer was in
underflow state Numerical
Buffer overflow Number of times the CDVT buffer was in overflow
state Numerical
Pointer mismatch Number of times a pointer mismatch was found Numerical
RX cells Number of cells received on the ATM channel Numerical
TX cells Number of cells transmitted on the ATM channel Numerical
Discarded cells Number of cells discarded from the ATM channel Numerical
Time Elapsed /
Start Time Time Elapsed is the period in seconds since the
beginning of the current interval.
Start Time is for intervals 1–24.
0–899
Valid intervals The number of intervals that are saved 0–24
Interval number The interval number to be displayed 0–last interval, max 24
0 if no interval
Default: 0
