 Administer the appropriate format to collect the most information. The
format depends on the capabilities of your CDR analyzing and recording
device.
 Use change trunk-group to display the Trunk Group screen.
 Enter y in the SMDR/CDR Reports field.
For DEFINITY G2:
 Use PROC275 WORD1 FIELD14 to turn on the CDR for incoming calls.
 Use PROC101 WORD1 FIELD8 to specify the trunk groups.
Call Traffic Report
This report provides hourly port usage data and counts the number of calls
originated by each port. By tracking normal traffic patterns, you can respond
quickly if an unusually high volume of calls begins to appear, especially after
business hours or during weekends, which might indicate hacker activity.
For DEFINITY ECS, DEFINITY G1, G3, and System 75, traffic data reports are
maintained for the last hour and the peak hour. For DEFINITY G2 and System 85,
traffic data is available via Monitor I which can store the data and analyze it over
specified periods.
Trunk Group Report
This report tracks call traffic on trunk groups at hourly intervals. Since trunk traffic
is fairly predictable, you can easily establish over time what is normal usage for
each trunk group. Use this report to watch for abnormal traffic patterns, such as
unusually high off-hour loading.
SAT, Manager I, and G3-MT Reporting
Traffic reporting capabilities are built-in and are obtained through the System
Administrator Tool (SAT), Manager I, and G3-MT terminals. These programs track
and record the usage of hardware and software features. The measurements
include peg counts (number of times accessed) and call seconds of usage. Traffic
measurements are maintained constantly and are available on demand. However,
reports are not archived and should therefore be printed to monitor a history of
traffic patterns.
For DEFINITY ECS, DEFINITY G1, G3, and System 75:
 To record traffic measurements:
— Use
change trunk-group to display the Trunk Group screen.
— In the Measured field, enter
both if you have BCMS and CMS,
internal if you have only BCMS, or external if you have only
CMS.
