background music. The Audio Module is used to store the IVR
messages.
When installed in the VoicePlus unit, this card stores the audio messages used
in the IVR Message Services. The number of messages that can be stored on
the card is defined in the "system.cfg".
A music I/O card may be installed for the MCU with one module per
MCU. This music extension is automatically detected by the system, and
the appropriate indication is shown in this dialog box (the Music
Extension check box is checked). The Music Extension is used to play
background music when participants are placed on hold during an Audio
only conference.

The video channels of the conference can be run by a standalone module,
which contains six units, or dual-video module, which is comprised of two
cards and contains 12 units in total. The video resources allocated to a
conference cannot be split between modules (the dual-video module is
considered as one module). All the participants in one video conference must
be managed using the same standalone or dual-video card.
When a Video+ card is installed on the MCU, in the Conference Properties–
Resource Force dialog box, the default Video settings are set to auto. When set
to auto the system first uses or allocates the resources on the Video+ card. To
have the system assign or use first the Standard Video module for this
conference, in the Conference Properties - Resource Force dialog box, select
Standard from the Video Card Type drop-down list. If more than one Standard
Video module is installed, you can select the specific module to use for this
conference by selecting the card's slot in the Slot drop-down list in the
Conference Properties - Resource Force dialog box.
If a dual-video module is used, one card is considered as the master and the
other slave. The definition of Master and Slave is automatically defined by
the system according to the slot in which the video cards are placed.
The maximum transmission capability of E1 lines (up to 1920 Kbps) can be
used in Transcoding or Continuous Presence conferences. To enable the high
line rate transmission, a newer video card version (version 1.43 and up) must
