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
Test Type 102 tests far end to near end loss by sending:
■ 9 seconds of 1004 Hz tone at 0dB
■ 1 second of quiet
■ This cycle is repeated until disconnect; disconnect is forced after
24 hours.
Test Type 105 tests 2-way loss, gain slope, and C-message and
C-notch noise by sending:
■ nine seconds of 1004 Hz at -16dB
■ one second of quiet
■ nine seconds of 404 Hz at -16dB
■ one second of quiet
■ nine seconds of 2804 Hz at -16dB
■ 30 seconds of quiet
■ one half second of Test Progress Tone (2225 Hz)
■ approximately 5 seconds of quiet
■ forced disconnect
