Digitone Receiver Audit; Automatic Static Data Downloading And System Maintenance; Routine Exercise Test - Nortel DMS-100 Series Maintenance Manual

4-28 ESA maintenance overview

Digitone receiver audit

The DTR audit monitors the status of the Digitone receivers. If a call process
possesses a DTR for more than two audits, the audit terminates the process.
The audit starts the clean-up process for the CPB. The audit also marks the
DTR as available. This action makes the DTR ready for use.
Error tracking detects receivers that are defective. Before the system changes
the assignment of a receiver, the system makes an error count check. When a
preset error threshold is reached, the system takes the receiver out of service.
An audit automatically returns to service the receiver and sets the error count
to zero.

Automatic static data downloading and system maintenance

The system automatically loads the ESA CC with static translations data. The
system can download this data after ESA RTS. Operating company personnel
can download this data manually, when the ESA CC is InSv.
At a time that office parameter RLCM_ESADUPD_HOUR determines, the
system updates the static translations data in the ESA CC. The system
performs the equivalent to the LoadPM CC ESADATA command in sequence
on each OPM with the ESA option. This ESA option is set in table LCMINV.
If the OPM runs another maintenance function at the automatic update time,
the automatic update process waits 30 s for the current function to finish. If
the current function continues to runs after 30 s, the system marks the OPM
with the in-service trouble (ISTb) status. The reason associated with the ISTb
is ESA STATIC DATA.
If the automatic update process fails during the loading of the static data, the
system marks the OPM with the SysB status. If the system fails to download
a table, the system generates an ESA log (ESA101 through ESA107). Each
log identifies and describes the table that failed to download. The remainder
of the tables are not downloaded. The system marks the OPM with the SysB
status and a reason of ESA DATA.

Routine exercise test

The system performs routine exercise (REX) tests on the ESA hardware. The
REX tests test ESA hardware that is not in use while the ESA processor
provides normal service. Perform these tests regularly. To perform this test,
297-8361-550 Standard 04.02 December 2004
Note: The OPM must not be on the same static update hour as a host
Remote Switching Center (RSC). This action corrupts static data.
Note 1: The OPM cannot enter ESA while the static data loads.
Note 2: If the OPM is out of service during the daily update, the system
updates the data as part of the normal RTS sequence.
