30-session MCU module 30 participants at 128 Kbps, 15 participants
at 384 Kbps, 9 participants at 768 Kbps, 3 participants at 1.5/2.0 Mbps,
or 45 voice-only participants.
Based on an Intel Pentium server running Windows NT, the IP/VC 3540
Application Server (AS) acts as a T.120 data collaboration conferencing server
allowing end users to perform slide presentations, whiteboard, and other applications
during a conference call.The 3540 AS has the same participant user limits
as the MCU module.
The IP/VC 3540 H.32-to-H.323 Gateway module provides ISDN H.320 to
IP-based H.323 translation.This is the same functionality provided by the 3520 and
3525, and has two PRI ports that can be configured at T1 or E1 speeds.Along with
other IP/VC products, it supports H.261 and H.263 for video format encoding.
Voice encoding, meanwhile, is performed with G.711, G.722, and G.728.
