MICB operation

The MICB provides flexibility in configuring conferences. Configure
conferences as follows:
•
•
•
The minimum duration of a conference is 15 minutes and the maximum
duration of a time-limited conference is 12 hours. The conference
starting time and duration can be scheduled in increments of 15
minutes.
The MICB card continuously monitors the audio signal level received
from each conferee and selects the two loudest signals for
transmission. The two loudest signals are summed and inserted into
the PCM sample prior to their transmission to other conferees. This
implementation of the two loudest signals improves the interrupting
capability of a conference connection and allows normal two-way
conversation that all conferees can hear.
In addition to the conferee timeslots, the MICB provides a timeslot
between the MPU and the DSP. This timeslot transmits message
prompts, entry and exit tones, or both that the system broadcasts to all
conferees when requested by the MPU.
The MICB uses ACD features to route external incoming trunk and local
line conferees to their appropriate conferences. The ACD features
provide queuing, chairperson features, and event reporting for each
conference.
The ACD features used by the MICB card provide the following:
•
•
