PPP Statistics

Transmit
The percentage of line capacity currently used for transmitting.

Receive
The percentage of line capacity currently used for receiving.

Ave. frames/s
The average per-second rate of transmitted and received frames on this line.

Frames/s
The current per-second rate of transmitted and received frames on this line.

Ave. bytes/s
The average per-second rate of transmitted and received bytes on this line.

Bytes/s
The current per-second rate of transmitted and received bytes on this line.

Clock timeout
The number of times the adapter firmware is unable to detect a clock signal. This increments only when external clocking is configured.

Overrun/Underrun
The number of erroneously long frames received. These are frames that are too large for the adapter to buffer. This can be caused by any of the following:

External clocking is configured and the device providing the clock is not working.
Internal clocking is configured and the adapter is not working properly.
The cable or line is defective.
The DataFire Electrical Interface is not configured correctly.

CRC
The number of frames received with cyclic redundancy check (CRC) errors. This indicates problems with the line itself or with the Clocking or Electrical Interface configuration.

Bit error
The number of frames received with bit errors.

Over flow
The number of received frames that exceeded the configured maximum frame size.

Abort
The number of abort frames received.

Frames w/o buffer
Number of frames transmitted and received for which there were insufficient buffers.

Good Frames
Number of frames transmitted and received without errors.

Good Bytes
Number of bytes transmitted and received without errors.

Sync 2000/570 Cards Only
Line Speed
Is the actual data rate of the line in bits-per-second.

Line Status
Is one of the following conditions: active, pending, or inactive.

Configured Baud Rate
Is the baud rate for the line in bits-per-second.

Max Frame Size
Is the maximum frame size used on this line.

Line Options
Is the line encoding scheme used on this line, either NRZ or NRZ1.

Duplex
Is either full- or half-duplex.

Cable Type
Is the cable type used to connected the adapter to the CSU/DSU.

Active Signals
Are the signals asserted, such as DTR, DSR, etc.
