Disaster recovery
MeetingPlace 8112 or 8106 server is a carrier-class conferencing platform
with several built-in redundancy and reliability features. This section
describes such features and provides recommendations for disaster recovery
planning when the following conditions occur:
with several built-in redundancy and reliability features. This section
describes such features and provides recommendations for disaster recovery
planning when the following conditions occur:
•
Data network failure
•
MeetingPlace 8112 or 8106 server failure
•
Site disaster
Data network failure
When a data network failure occurs, assuming that the voice network is still in
operation, MeetingPlace 8112 or 8106 continues to operate. This means that
previously scheduled meetings can start and meetings that are taking place
can continue.
operation, MeetingPlace 8112 or 8106 continues to operate. This means that
previously scheduled meetings can start and meetings that are taking place
can continue.
Scheduling future or immediate meetings, however, is limited to the voice
user interface only, and no notifications are available until the data network is
backed up. Web conferences are affected because the data network is critical
to web conferencing. This functions similarly to the Continuous Service
Mode currently available in the PCI platform.

Large conference room
Average. Should not be a problem, but a speakerphone
is generally required. With these units, groups of 10 to
15 people can be handled comfortably, although
extension microphones are recommended. Check the
room for hard surfaces and reflective walls, which
produce acoustic echo.

Executive board room
Average. This type of room presents a challenge to
audio quality. Board rooms are usually large with
highly reflective surfaces. Because acoustic echo
problems can be expected, it is highly recommended
that audio systems (microphones and speakers) and a
high-performance echo canceler are used.

Auditorium
Average. Problems similar to those of the board room,
with the added problem of increased ambient noise.
The use of high-performance audio equipment is
essential.
