The following table describes the channel counters seen in the about output of the dspchancnt command on an AUSM connection.

Counter (dspchancnt/dspsarcnt)	Description
ChanIngressReceiveCells	The total number of cells received from the port side on this channel.
ChanIngressEfciSetRcvCells	The number of cells received from the port side on this channel that has the CLP bit in the ATM Header set to 1.
ChanIngressEfciSetXmtCells	The number of cells received from the port side on this channel that has the EFCI bit in the ATM Header set to 1.
ChanIngressUpcClpSetCells	The number of cells transmitted to the network with the EFCI bit in the ATM Header set to1.
ChanIngressQfullDiscardCells	The number of cells (CLP=0) tagged (CLP=1) because of SCR violation.
ChanIngressClpSetDiscardCells	The number of cells discarded due to the ingress channel queue full condition.
ChanIngressTransmitCells	The following:-* CLP=0+1 cells discarded due to PCR violation. * CLP=0+1 cells discarded due to SCR violation when CLP tagging is disabled. * CLP=1 cells dropped due to the queue length exceeding the CLP threshold. When the received cell rate is greater than 100% then the cells discarded are due to PCR violation.
ChanShelfAlarmDiscardCells	The total number of cells transmitted to the network.
ChanEarlyPacketDiscardCells	The total number of cells discarded due to a shelf alarm condition.
ChanPartialPacketDiscardCells	The total number of cells discarded to Early Packet Discard
ChanIngressTransmitAAL5Frame	The total number of AAL5 Frames transmitted to the network.
ChanIngressReceiveCellRate	The total number of cells received from the port side in one second.
ChanIngressReceiveUtilization	The percentage utilization of the cells received from the port side with respect to the PCR of the channel.
ChanIngressTransmitCellRate	The total number of cells transmitted to the network in one second.
ChanIngressTransmitUtilization	The percentage utilization of the cells transmited to the network with respect to the PCR of the channel.
ChanEgressReceiveCellRate	The total number of cells received from the network in one second
ChanEgressReceiveUtilization	The percentage utilization of the cells received from the network with respect to the PCR of the channel.
ChanEgressPortQFullDiscard- Cells	The total number of cells discarded due to the port queue full condition for the queue corresponding to the service type of this channel. For example if the channel for which the counters are monitored is a CBR channel then this count corresponds to the CBR queue for that port, and this queue is common for all the CBR channels on that port.
ChanEgressPortQClpThreshDis- cardCells	The total number of cells discarded due to the port queue length exceeding the CLP threshold. It is similar to ChanEgressPortQFullDiscardCells above.
ChanTransmitFifoFullCount	The number of times the card tried to send a cell to the network but found the transmit FIFO to be full. This FIFO becomes full when the BNM is congested.
Total Cells[Tx]	The total number of cells transmitted to the network.
Total CellsCLP[Tx]	The number of cells with CLP bit set transmitted to the network.
Total CellsAIS[Tx]	The number of AIS OAM cells transmitted to the network.
Total CellsFERF[Tx]	The number of FERF OAM cells transmitted to the network.
Total CellsEnd2EndLpBk[Tx]	The number End-to-End loopback OAM cells transmitted to the network.
Total CellsSegmentLpBk[Tx]	The number Segment loopback OAM cells transmitted to the network.
Total Cells[Rx]	The total number of cells received from the network.
Total CellsCLP[Rx]	The number of cells with CLP bit set received from the network.
Total CellsAIS[Rx]	The number of AIS OAM cells received from the network.
Total CellsFERF[Rx]	The number of FERF OAM cells received from the network.
