The MUX Module receives information in one of the following standard
formats:
•
Hyper-channel (or multi-rate ISDN)
•
Aggregated channel using the BONDING Mode 1 standard from 2
channels of 56/64 Kbps to 30 channels of 56/64 Kbps
•
Aggregated channel using the ITU-T H.221 standard for channels with
data rates of up to 6x56/64 Kbps
The MUX Module supports up to 16 MUX ports. Each MUX port supports
one site.
The MUX Module supports:
•
Up to 16 ports at low data rates of 128-384 Kbps
•
Up to 8 ports at medium data rates of up to 768 Kbps
•
Up to 4 ports at high data rates of up to 1536/1920 Kbps
For operating each terminal at its maximum data rate capacity, the MUX
Module supports mixed rate ports. For example, some ports in a given module
can operate at 128 Kbps while, simultaneously other ports can operate at 768
Kbps.
The MUX module is used in the Greet and Guide mode to store the video
slide, which is displayed to the participants waiting in the Welcome or On
Hold queues.
