This chapter describes how to conduct a multipoint videoconference.
For conducting a multipoint videoconference, installation of the optional
PCS-323M1 MCU software (for LAN connection) based on the H.323
standard or the optional PCS-320M1 MCU software (for ISDN connection)
based on the H.320 standard is required.
Multipoint videoconference among up to ten points including the local site is
available when connecting via a LAN.
When connecting via ISDN lines, you can conduct a multipoint
videoconference among up to six points including the local site. You can use
a normal phone at up to five points over ISDN.
Even if both PCS-323M1 and PCS-320M1 MCU software is installed, you cannot
conduct a multipoint videoconference using both LAN and ISDN connections.
Restrictions on the use of the MCU software
When a multipoint videoconference is held via LAN
The bandwidth is automatically set so that the total value of all the points is 2
Mbps maximum. The supported video modes are H.263 and H.261 only.
When a multipoint videoconference is held via ISDN
The same number of channels should be used on all the points and the total
channels are up to 12B.
The supported video modes are H.263 and H.261 only, and the audio modes
G.711, G.722 and G.728 only.
