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 one
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.
ISDN-BRI Service
SPID
This field shows whether or not the link is associated with the
Service SPID. If the link is associated with the Service SPID,
this field contains a “yes” and the extension field is blank;
otherwise, this field is blank. Service SPID is a feature used by
the system technician to check building wiring between the
switch and the BRI endpoint.
