This includes frames retransmitted and frames sent on transmissions stopped by transmit underrun, in addition to successful transmissions.PD (11,0)LSFRCVTotal number of frames received: This includes information (I), unnumbered information (UI), and supervisory (S) frames received from the remote link station. This includes no errors.PD (11,0)LSBTRNTotal bytes transmitted: The total number of bytes transmitted to a remote link station. This includes bytes retransmitted and bytes sent on transmissions stopped by a transmit underrun, in addition to successful transmissions.PD (11,0)LSBRCVTotal bytes received: The total number of bytes received from the remote link station. This includes no errors.PD (11,0)LQTOCTotal outgoing calls: The number of outgoing call attempts. For X.31 this includes outgoing SETUP messages requesting a packet switched connection.

For X.31 this includes incoming SETUP messages requesting a packet switched connection. For Q.932, incoming REGISTER messages are not included in this count.PD (11,0)LQRICRejected incoming calls: The number of incoming calls that are rejected by the TE. For passive bus, the call may be intended for another TE that shares the same passive bus. This includes calls rejected both directly by the IOP and by the IOM. For X.31 this includes rejected incoming SETUP messages requesting a packet switched connection.
