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 f ield 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 o ne
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-PT S
before the alarm is raised. If there are no TN744s 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 f ar-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.
