PMS-PRNT/JNL-PRNT (PMS Printer Link)
NOTE:
PMS-PRNT stands for the pms-log printer. JNL-PRNT stands for the
wakeup-log printer. Since the maintenance strategy for the b oth the
JNL-PRNT and PMS-PRNT MOs is the same, both of these MOs are
described in this section.
There can be up to two journal p rinters: the wakeup-log p rinter, which is shared
between the Automatic Wakeup feature and the Emergency Acce ss to Attendant
feature to print scheduled reports and log of events, and the pms-log printer,
which is used as a bac kup of the PMS output device to print the aud it trail data of
all PMS transactions executed by the system and the PMS Housekeeping Status
Change events while the PMS Printer Link is not available. The journal printer link
is administered to a data extens ion that provides a standard EIA 232C interface
to the printer. The printer can b e connected throug h a data module (PDM,
MPDM, DTDM) and a port on the TN754 or TN754B Digital Line circuit p ack, or
through an ADU and a port on the TN726 Data Line circuit pack.
PMS Printer Link Maintenance provides a strategy in the system for maintaining
the link between the system and a PMS device (an e xternal Journal Printer
device). The strategy inclu des a set of tests for periodi c diagnosis, d etection of
errors during normal operat ion, actions for troubleshooting, a nd raising alarms
for serious problems. PMS Printer Link Maintenance uses a try-and -wait
mechanism for maintaining the PMS Printer Link. If a PMS Printer Link is torn
down due to an error, PMS Printer Link Maintenance intends to b ring the link up
immediately. If the trial of Link Setup fails, PMS Link Maintenance waits for five
minutes before the next retry. If the number of retries reaches the value of 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 e xample, the external printer
device, Data Module (PDM/MPDM/DTDM) and Digital Line Port of TN754 or
TN754B Digital Line circuit pac k, ADU and Data Line Port of TN726 Data Line
circuit pack). I f PMS Printer Link Maintenance cannot restore the PMS Printer
Link, then the maintenance tests of these individual components of the PM S Link
must be executed to d iagnose faults.
