System Clocks
Interchange
On High and Critical Reliability systems, this option causes a
Tone-Clock interchange in each port network with duplicated
Tone-Clock circuit packs. Each port network interchanges into
the standby Tone-Clock for 20 seconds and then back to the
Tone-Clock that was originally active. This field indicates on
which days the interchanges are to take place. Valid entries are
daily
, days of the week, or
no
.”No” specifies that interchanges
be executed. (no)
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)
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, TN718,
TN420, or TN756; TN2182 and TN744 (suffix C or later) each
have 8 TTRs. 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.
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, TN718,
TN420, or TN756; TN2182 and TN744 (suffix C or later) each
have 8 CPTRs. To alarm the first occurrence of a CPTR being
taken out of service, set this field to the total number of CPTRs in
the switch.
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 or TN2182 circuit pack. To alarm the first occurrence of a
CLSFY-PT being taken out of service, set this field to the total
number of CLSFY-PTs. If there are no TN744 or TN2182 circuit
packs in the system, leave this field blank.
Test Type 100,
Test Type 102,
Test Type 105
An extension assigned to receive tie-trunk calls from other
switches with test line origination capability. The system
responds by sending a sequence of test tones. Test Type 100
tests far-end to near-end loss and C-message by sending:
■ 5.5 seconds of 1004 Hz tone at 0dB
■ Quiet until disconnect; disconnect is forced after 1 minute
ISDN-PRI Test
Call Extension
The extension used by a far-end ISDN node to place a call to the
system to test the ISDN-PRI trunks between the far-end and the
system.
