Figure 116: Observation of trunk group table
This screen displays the hour, minutes, and date of the observation and a table showing
the characteristics of the trunk group observed, including the number of lines in service.
DIRECTION
: D: Outgoing or A: incoming
to
: Busy rate for lines in the trunk group
NC
: Number of calls in the trunk group
SA
: Saturation (significant in outgoing mode only).
BU
: Busy (number of incoming calls for <busy subscribers>)
RE
: Free (number of incoming calls for <free subscribers>)
SP
: Conversation (number of voice communications)
QR
: Quality rate is equal to SP X 100): NC
The first line (5) is not always significant for calculation of the busy rate.
Example:
Calculation is as follows for an outgoing and incoming call on the same trunk group: busy
rate for all lines in the trunk group in service multiplied by 100, divided by the reference
time, and multiplied by the number of lines in service.
In the above table, busy time is from 08:36 to 08:37, that is, 1 minute, and the reference
time is 1 MIN (test). The number of lines is 2, so we have 60 sec. x 100: 60 sec. x 2 = 50%
busy rate for the trunk group lines. The trunk group can be observed by entering the
minimum rate.
Use the commands "Next" and "Previous" to move from overall trunk group observation,
from busy rate to another rate.
