Minimum Maintenance Thresholds (Before Notification)
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.
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.
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 eight 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.
MMIs
The
MMIs
field contains the minimum number of MMI ports needed for the
Multimedia Call Handling (MMCH) feature to run efficiently. The MMCH
feature must be enabled on the System Parameters Customer Options
form before the
MMIs
field can be changed to a number greater than zero.
If the number of in-service Multimedia Interface (MMI) ports falls below the
minimum port capacity (valid entries between 0-128), a MMI-LEV error is
logged. Each MMI circuit pack contains a maximum of 32 ports. To alarm
the first occurrence of an MMI being taken out of service, set this field to the
total number of MMI ports. If this outage continues for 15 minutes, a major
alarm is raised.
VCs
The
VCs
field contains the minimum number of VC ports needed for the
Multimedia Call Handling (MMCH) feature. The MMCH feature must be
enabled on the System Parameters Customer Options form before the
VCs
field can be changed to a number greater than 0. Each VC circuit
pack contains 16 physical ports: eight ports are reserved for VC-DSPPT
ports, and the remaining eight ports are designated as VC-SUMPT ports.
The eight DSP ports are made up of four encoder and four decoder
resources that encode and decode audio formats. Thus, one VC circuit
pack is required for every eight ports of MMCH port capacity. If the number
of in-service VC ports falls below the MMCH port capacity (valid entries
between 0 and 128), a VEC-LEV error is logged. To alarm the first
occurrence of a VC port being taken out of service, set this field to the total
number of VC ports. If this outage continues for 15 minutes a major alarm
is raised.
