This dashlet helps you identify the route groups
experiencing high, average bouncing busy hour (ABBH) traffic. ABBH is
calculated by analyzing the traffic load on a switching system during the peak
hour of each day, over a certain period (typically one week), and then
calculating the average for the time period.
Prerequisite :The maximum capacity for the CDR utilization
trunks must be configured to see the available capacity in this dashlets. To configure maximum
capacity for the CDR utilization trunks click
Busy-Hour Route Group? at the top left corner of the dashlet, below the
You can also view
the following capacity details of the trunk groups or route groups:
- Available Capacity
- Average Bouncing Busy Hour
- Maximum Bouncing Busy Hour
The maximum capacity
required for a resource is calculated from the maximum BBH value, represented
in erlangs. Maximum BBH is the maximum Bouncing Busy Hour value of a particular
route group for the selected time period. BBH is the peak value of that day.
The average capacity
required is calculated from the ABBH value. Average capacity, here, means the
minimum capacity required for a resource to maintain good traffic flow. ABBH is
the average of all BBH values of a particular route group for the selected time
ABBH value will
be calculated only for the working days, for the selected time period. For
example, if you have specified the time period as one week, Analytics will
first calculate the ABBH for seven days. The days that have BBH value less than
25 percentage of ABBH are considered as non-working days. Analytics ignores the
non-working days and calculates the ABBH value for all the other days of that
Analytics uses the Grade of Service value as 0.01 to calculate the average
required capacity and maximum required capacity. To calculate the average and
maximum required capacity for a different GOS (for example, 0.1, 0.001 and so
on)you must edit the
gos.properties file. See
Editing the GOS Properties
BBH of the current
day is calculated only at the end of the day and you can see it only on the
next day. There is no Inbound or Outbound traffic for ABBH. It is applicable
only for BBH.
In the detailed
analysis page, you can filter the details displayed based on route group,
traffic type, direction, bandwidth used, or cluster (this drop-down list is
enabled only if you choose the Select option in the detailed view). When you
select a cluster, all the devices for that cluster gets listed, regardless of
whether the devices are maximum or least utilized.
In addition, you can view the traffic type and direction of the
associated trunks for a route group when you select
Trunks. The tabular view (pops up when the legend is clicked) also
displays associated trunks details for a route group.
You need to
configure the maximum capacity for the CDR utilization trunks in order to see
the available capacity in the dashlets. If the maximum capacity for the CDR
trunks is not configured or zero, the data for these trunks will not be shown
in the dashlet.
To configure maximum capacity for CDR trunks, see
Configuring Maximum Capacity for a Trunk or Gateway.
This dashlet will
not include the details for the calls processed on VCS.
