POINT-TO-POINT
CONFERENCING
The RADVISION PRI Gateway enables direct video, voice, and data
communication between an H.320 (ISDN) terminal and H.323 (IP) terminals at
bandwidths of up to 1472 Kbps (23B bonding for T1) and up to 1920 Kbps (30B
bonding for E1) (see Figure 1-2).

ABOUT MULTIPOINT
CONFERENCING
Together with the RADVISION MCU, the RADVISION PRI Gateway enables
H.320 ISDN terminals to participate in a mixed ISDN-IP multipoint multimedia
conference with IP network endpoints (see Figure 1-3).
For example, when an H.320 ISDN terminal wants to participate in a multipoint
conference with H.323 IP endpoints, the H.320 ISDN terminal can either join
the multipoint conference by dialing to the Gateway, or be invited into the
conference by one of the participating IP endpoints. In either case, the Gateway
connects the ISDN terminal to the
RADVISION MCU, enabling it to participate
in the multipoint conference.
