Scheduled Maintenance
A series of maintenance tests and op erations runs automatically every day
according to the schedule and setting s specified in the following fields.
Start Time The hour and minute (24-hour notation) at which d aily scheduled
maintenance begins. (22:00 )
Stop Time Time (hour and minute) when scheduled daily maintenance stop s.
If any daily maintenance op erations are not completed b y this time,
the system notes where in the sequence i t stopped and p erform

Daily
Maintenance This display-only field simp ly represents the series of tests that are
always run by maintenance software as p art of daily maintenance.
Save Translation This field indicates on whic h days translation data in memory will
automatically be saved to the Mass Storage System disk and/or
tape devices d uring scheduled maintenance. The save operation is
first made to disk, followed b y a disk backup to tape. On systems
with d upl icat ed SPEs, t ransl ation data is sav ed on both SPEs. Vali d
entries are daily, days of the week, or no. “No” spec ifies that no
automatic saves are to be exec uted. (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 ded icated to use by the c ontrol
channel. At any one time, the control c hannel in each PN is carried
on only one of the two busses. This field ind icates on which days
the control channel in eac h port network will be switched from one
of the paired TDM busses to the other. Valid entries ar e daily, days
of the week, or no. “No” sp ecifies that no interchange b e executed.

EXP-LINK

Minimum
Threshold for
TTRs
When the number of touch tone receive rs (TTRs) in service falls
below this number (4 to 200), a WARNING alarm is raised ag ainst
TTR-LEV. These are also known as dual-tone multifreq uency
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.
