wait for PSI card activity before reporting a PSI failure.
The transmission speed is the transmission speed (in bits per second) of

is being used, the modem determines the speed.
The connect duration is how long a level 2 connection has been
maintained.
Data bytes sent is the total number of bytes that have been sent in the
information field of an Information (I) frame.
Overhead bytes sent is the total number of SDLC bytes that have been
sent. The total includes flags and Frame Check Sequence (FCS) bytes.
Total frames sent is the total number of frames that have been sent.
Data frames sent is the total number of Information (I) frames that
have been sent.
Bytes retransmitted is the number of non-SDLC data bytes that have

Data bytes rcvd is the total number of bytes that have been received in
the information field of an Information (I) frame.
Overhead bytes rcvd is the total number of SDLC bytes that have been
received. The total includes flags and Frame Check Sequence (FCS)
bytes.
Total frames rcvd is the total number of frames that have been
received.
Data frames rcvd is the total number of Information (I) frames that
have been received.
Oversized frames rcvd is the total number of received frames that
exceed the maximum configured frame size.
Aborted frames rcvd is the total number of aborted frames that were
