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

5-20 ESA maintenance overview

Digitone receiver audit

The DTR audit monitors the status of the Digitone receivers. If a call process
possesses a DTR for longer than two audits, the audit terminates the process.
A cleanup process starts for the call process block. The audit also marks the
DTR as free, which makes the DTR ready for use.
Error tracking detects receivers that are defective. Before a receiver is
unassigned, an error count check occurs. When a preset error threshold is
reached, the audit takes the receiver out of service. An audit returns the
receiver to service and sets the error count to zero.

Automatic static data downloading and system maintenance

The system loads the ESA CC with static translations data. The system or
operating company personnel can download this data after ESA RTS when the
ESA CC is InSv.
At a time determined by the office parameter RLCM_ESADUPD_HOUR, the
system updates the static translations data in the ESA CC. The system
performs the equivalent to the LOADPM PM CC ESADATA command in
sequence on each Star Hub with the ESA option. This ESA option is set in
table LCMINV.
If the Star Hub runs another maintenance function at the automatic update
time, the automatic update process waits 30 s for the function that now runs to
finish. If the function runs after 30 s, the Star Hub goes to in-service trouble
(ISTb) status. The reason for the ISTb is ESA STATIC DATA.
If the automatic update process fails during the loading of the static data, the
Star Hub goes to SysB status. If a failure occurs when the system downloads
a table, the system generates ESA logs, ESA101 through ESA107. Each log
identifies and describes the table that fails to download. The system does not
download the remainder of the tables. The Star Hub goes to SysB status and
receives a reason of ESA DATA.
Note 1: The Star Hub cannot enter ESA while the system loads the static
data.
Note 2: If the Star Hub is out of service during the daily update, the system
updates the data as part of the normal RTS sequence.

Routine exercise test

The REX tests are a series of tests performed on the ESA hardware. This
hardware is not in use while the ESA software in the RCP provides normal
service. These tests can occur at regular intervals or through the TST (test)
command with the REX option. These tests require that units of the Star Hub
are InSv.
