ADTRAN 612, 616, 606, 624, 604 system manual L2 Protocol ATM-NET-ATM Status ATM Status

Section 4 User Interface Guide Total Access 600 Series System Manual

QOS > PEAK CELL RATE

Defines the peak cell rate for the data PVC. This setting is normally used for Undefined Bit Rate (UBR) connections and is calculated using the following equation:

Peak Cell Rate = Bit Rate / 424

The total of all peak cell rates for the ATM network connection must not exceed the line rate. The range for this parameter is 0 to 3623.

L2 PROTOCOL (ATM–NET–ATM) > STATUS

Displays all available ATM statistics (both overall and PVC-specific).

L2 PROTOCOL (ATM–NET–ATM) > STATUS > ATM STATUS

Displays overall ATM link performance statistics. The following statistics are available:

AP: TX CELLS	Number of cells transmitted over the ATM link.
AP: RX CELLS	Number of cells received over the ATM link.
AP: RX OAM CELLS	Number of Operation, Administration, and Maintenance
	cells received on the ATM link. OAM cells provide
	network fault indications, performance information, and
	data and diagnostic functions.
AP: RECEIVE CELL	Number of cells received that are received and
DISCARDED	discarded. An incrementing count in this field could
	indicate a configuration problem with the ATM layer.
AP: RECEIVE CELL ERRORS	Number of cells received that contain a Header Error
	Control (HEC) error. The HEC is a CRC code located in
	the last byte of the ATM cell header that’s used for
	checking integrity.
AP: SYNC	Indicates cell delineation at the ATM layer.
AP: OUT OF CELL	Indicates loss of cell delineation at the ATM layer.
AAL5: TRANSMIT FRAMES	Number of ATM Adaptation Layer Type 5 frames
	transmitted on the ATM link.
AAL5: RECEIVE FRAMES	Number of ATM Adaptation Layer Type 5 frames
	received on the ATM link.
AAL5: TRANSMIT DISCARDED	Number of ATM Adaptation Layer Type 5 transmitted
FRAMES	frames that were discarded before transmission.
AAL5: RECEIVE ERRORS	Number of ATM Adaptation Layer Type 5 frames that
	were received and contained errors.
AAL5: RECEIVE DISCARDED	Number of ATM Adaptation Layer Type 5 frames that
FRAMES	were received but then discarded.
AAL5: NO ATM FRAMES	Internal ADTRAN use only.
AAL5: NO DATA PACKETS	Internal ADTRAN use only.

L2 PROTOCOL (ATM–NET–ATM) > STATUS > ATM STATUS > CLEAR STATS

Clears all ATM statistics contained in the ATM status field and returns all counters to 0.
