SPE
Interchange
On systems with duplicated SPEs, this field indicates on which days an
SPE interchange will be executed during scheduled maintenance.
Valid entries are daily, days of the week, or no. "No" specifies no
scheduled interchanges. (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 4 TTRs on each TN748 Tone Detector circuit pack, and up to
50 TN748s in a system. To alarm the first occurrence of a TTR being
taken out of service, set this field to 4 times the number of TN748s. If
this number is set to more than three less than the total number of
TTRs, a port network with only one TN748 could lose all of its TTRs
before this alarm is raised.
Minimum
Threshold for
CPTRs
When the number of call progress tone receivers in service falls below
this number (2 to 100), a WARNING alarm is raised against TTR-LEV.
These are also known as general purpose tone detectors (GPTDs).
There are 2 CPTRs on each TN748 Tone Detector circuit pack, and up
to 50 TN748s in a system. To alarm the first occurrence of a CPTR
being taken out of service, set this field to 2 times the number of
TN748s. If this number is set to more than one less than the total
number of TTRs, a port network with only one TN748 could lose all of its
CPTRs before this alarm is raised.
Minimum
Threshold for
Call
Classifier
Ports
When the number of call classifier ports (CLSFY-PTs) in service falls
below this number, a WARNING alarm is raised against TTR-LEV. Valid
entries are 1 to 200. There are 8 ports on each TN744 Call Classifier
circuit pack, and up to 25 TN744s in a system. To alarm the first
occurrence of a CLSFY-PT being taken out of service, set this field to 8
times the number of TN744s. If this number is set to more than 7 less
than the total number of CSLFY-PTs in the system, a port network with
only one TN744 could lose all of its CLSFY-PTS before the alarm is
raised. If there are no TN744s in the system, leave this field blank.
