Collection Services data files: QAPMIDLC
This database file includes integrated services digital network (ISDN) data link control file entries and lists the fields in the ISDN data link control (IDLC) file.
| Field Name | Description | Attribute |
|---|---|---|
| INTNUM | Interval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command. | PD (5,0) |
| DTETIM | Interval date (yymmdd) and time (hhmmss): The date and time of the sample interval. | C (12) |
| INTSEC | Elapsed interval seconds: The number of seconds since the last sample interval. | PD (7,0) |
| IOPRN | IOP resource name. | C(10) |
| ISIOP | Reserved | C (1) |
| ISTYPE | The resource type of the IOP or adapter represented by this record. | C (4) |
| ISLND | Line description: The name of the line description. | C (10) |
| ISNWI | Network interface description: The name of the network interface description. | C (10) |
| ISLSP | Link speed: The speed of this channel in bits per second. | PD (11,0) |
| ISPRCL | Protocol type: I for IDLC. | C (1) |
| ILCRCE | Receive CRC errors: The number of received frames that contain a cycle redundancy check (CRC) error. | PD (11,0) |
| ILSFE | Short frame errors: The number of short frames received. A short frame is a frame that has fewer octets between its start flag and end flag than is permitted. | PD (11,0) |
| ILORUN | Receive overrun: The number of times the ISDN subsystem could not keep pace with incoming data because of local controller overload. | PD (11,0) |
| ILURUN | Transmit underrun: The number of times the ISDN subsystem could not keep pace with outgoing data because of local controller overload. | PD (11,0) |
| ILABRT | Aborts received: The number of frames received that contained HDLC abort indicators. | PD (11,0) |
| ILFRIE | Frames received in error: The sum of receive CRC errors, short frame errors, receive overrun, transmit underrun, aborts received, and frame sequence errors (ILCRCE, ILSFE, ILORUN, ILURUN, ILABRT, ISSEQE). | PD (11,0) |
| ISFRT | Retransmitted frames. | PD (11,0) |
| ISSEQE | Sequence errors: The number of received frames that contained sequence numbers indicating frames were lost. | PD (11,0) |
| ISFTRN | Total number of frames transmitted: This includes information (I), unnumbered information (UI), and supervisory (S) frames sent to a remote link station. This includes frames retransmitted and frames sent on transmissions stopped by transmit underruns, in addition to successful transmissions. | PD (11,0) |
| ISFRCV | Total 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) |
| ISBTRN | Total 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) |
| ISBRCV | Total bytes received: The total number of bytes received from the remote link station. This includes no errors. | PD (11,0) |
| ISB1 | B1 channel: Set to one if the B1 channel was used. | PD (1,0) |
| ISB2 | B2 channel: Set to one if the B2 channel was used. | PD (1,0) |
| ISCHAN | B channel used: The B channel used is associated with a bit in this field being set to 1. Bit 0 (most significant bit) and 31 (least significant bit) are reserved. Bits 1 to 30 are associated with B channels 30 to 1, respectively. | C (4) |
