About Point-to-Point Conferencing

The Cisco IPVC 3521 BRI Gateway enables direct video, voice, and data communication between an
H.320 (ISDN) terminal and H.323 (IP) terminals at bandwidths of up to 512 Kbps (4 BRI lines) using
bonding mode 1 (see
The Cisco IPVC 3526 PRI Gateway and Cisco IPVC 3540 PRI Gateway enable 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 1-8

About Multipoint Conferencing

Together with the Cisco IPVC 35xx MCU, the Cisco IPVC 3500 Series Gateway enables H.320 ISDN
terminals to participate in a mixed ISDN-IP multipoint multimedia conference with IP network
endpoints (see
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 Cisco IPVC 35xx MCU enabling it to participate in the
multipoint conference.
