Scheduled Maintenance
A series of maintenance tests and operations runs automatically every day
according to the schedule and settings specified in the following fields.
Start Time
The hour and minute (24-hour notation) at which daily scheduled
maintenance begins. (22:00)
Stop Time
Time (hour and minute) when scheduled daily maintenance stops.
If any daily maintenance operations are not completed by this time,
the system notes where in the sequence it stopped and perform
those operations during the next scheduled daily maintenance.
Daily
Maintenance
This display-only field simply represents the series of tests that are
always run by maintenance software as part of daily maintenance.
Save Translation
This field indicates on which days translation data in memory will
automatically be saved to the Mass Storage System disk and/or
tape devices during scheduled maintenance. The save operation is
first made to disk, followed by a disk backup to tape. On systems
with duplicated SPEs, translation data is saved on both SPEs. Valid
entries are
daily
, days of the week, or
no
. “No” specifies that no
automatic saves are to be executed. (daily)
Control Channel
Interchange
Each port network has a pair of TDM busses called A and B, each
of which has a set of time slots dedicated to use by the control
channel. At any one time, the control channel in each PN is carried
on only one of the two busses. This field indicates on which days
the control channel in each port network will be switched from one
of the paired TDM busses to the other. Valid entries are
daily
, days
of the week, or
no
. “No” specifies that no interchange be executed.
(no)
EXP-LINK
Interchange
This field indicates whether or not the expansion links between
port-networks are interchanged as part of scheduled maintenance.
The value “daily'' means that EXP-LINK interchange occurs
automatically everyday. The value “no'' means that EXP-LINK
interchange is not done automatically as part of scheduled
maintenance. Values represented by the days of the week mean
that EXP-LINK interchange occurs automatically on the specified
day only. Since EXP-LINK interchange only applies to duplicated
systems, simplex systems do not display this field. (no)
Minimum
Threshold for
TTRs
When the number of touch tone receivers (TTRs) in service falls
below this number (4 to 200), a WARNING alarm is raised against
TTR-LEV. These are also known as dual-tone multifrequency
receivers (DTMRs). There are 8 TTRs on each TN2182. To alarm
the first occurrence of a TTR being taken out of service, set this
field to the total number of TTRs in the switch.
