418 IP Line administration using TM 3.1
Operational Measurement report scheduling and generation
Operational Measurement (OM) reports provide important statistical and
traffic information and feedback to the system administrator to better
engineer the system. The information stored in the OM file applies only to
the calls routed over the IP network by way of IP Line. OM reports give a
quantitative view of system performance, such as jitter.
TM is used to support Operational Measurements on the systems.
The OM reports are a collection of data from all the Voice Gateway Media
Cards in the network. OM data is written to a file every hour. At midnight,
the OM file is copied to a backup file, and the new day starts with a new file.
TM uses the following naming convention for the IP Line OM file names:
An example is ipline50_10_2002_file1.csv. This comma-delimited file
opens in a program that interprets the .csv file, such as Microsoft Excel or
any other comma-delimited file reader.
OM reports are generated on demand or on a preselected schedule. When
a report is generated, the application retrieves the latest OM data from each
Voice Gateway Media Card defined in TM.
Under certain conditions, the OM report is not available, as follows:
•
•
The following error messages are generated when requesting the OM
report during the first hour:

To schedule a generated OM Report, follow the steps in

ipline31_MM_YYYY_file1.csv
The MM (month) portion of the file name is only one character for the
months of January to September (1 to 9). The remaining three months
appear as two-digit numbers (10, 11, and 12).

the first hour after installing a new Voice Gateway Media Card
on TM: "fails to transfer the OM file"

Nortel recommends that report generation be scheduled once a day.
