The errors and tests for PMS-PRNT also apply to JNL-PRNT.

A journal printer is a printer to which Emergency Access to Attendant, Wakeup and Property Management System (PMS) events are printed as they occur. The PMS-log printer is used as a backup of the PMS output device to print an audit trail of every PMS transaction and Housekeeping Status Change event when the PMS Printer Link is not available. There may be one or two journal printers. If there is one, every event is printed there. If there are 2, then emergency access, wakeup events, and scheduled reports are printed at one printer (JNL-PRNT), and PMS events are printed at the other (PMS-PRNT).

The scheduled report printer is where summaries of daily wakeup activity and emergency access activity are printed. If the customer requests a summary report, the report will be printed exactly once per day.

The distinction between Journal and Scheduled report printers is logical rather than physical. Whether or not there are two printers, the scheduled reports are always sent to the printer that journals the wakeup and emergency access events. A scheduled report will temporarily suspend the journal activity. Upon completion of the scheduled report, journaling will be resumed after the printing of every withheld event.

The journal printer device connects to the system via a data module (PDM, MPDM, DTDM) connected to a port on PROCR.

PMS/JOURNAL Printer Link Maintenance provides a strategy for maintaining the link between the system and a PMS device that is an external Journal Printer device. The strategy includes a set of tests for periodic diagnosis, detection of errors during normal operation, actions for troubleshooting, and raising alarms for serious problems. PMS Printer Link Maintenance uses a try-and-wait mechanism. If a PMS Printer Link is torn down due to an error, PMS Printer Link Maintenance will try to bring the link up immediately. If the link setup fails, PMS Link Maintenance will wait for five minutes before the next trial. If the number of retries reaches a threshold (15), a Minor alarm is raised for service attention.

PMS Printer Link Maintenance does not cover the maintenance of the elements composing the journal printer physical link (for instance, the external printer device, Data Module (PDM/MPDM/DTDM), Digital Line Port or ADU and Data Line Port). If PMS Printer Link maintenance cannot restore the PMS Printer Link, then the maintenance tests of individual components of the PMS Link must be executed to diagnose faults.

The list pms-down command lists every meaningful event to the PMS that occurred while the link between the switch and the PMS was down. For example, any room status codes entered by hotel housekeeping staff during a time of PMS outage would be reflected in this report.
