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.
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: 8 ports are reserved for VC-DSPPT ports, and the
remaining 8 ports are designated as VC-SUMPT ports. The 8
DSP ports are made up of 4 encoder and 4 decoder resources
that encode and decode audio formats. Thus,
one VC circuit
pack is required for every 8 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.
Terminating Trunk Transmission Test (Extension)
Test Type 100
This field specifies extensions assigned to receive tie-trunk calls
from other switches that have 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 0 dB
■ Quiet until disconnect; disconnect is forced after one minute
