IVR/Greet & Guide Welcome Slide
Up to four video slides can be stored on the MUX+ card. The Welcome slide
is downloaded to all MUX+ cards if more than one card is present on the
MGC+ MCU.
MUX+ Port Capacity
MUX+ resources are allocated at the reservation stage. MUX+ resources are
calculated according to the relative weight assigned to the different line rates.
Using the dynamic allocation mechanism, the MUX+ eliminates
fragmentation and enables better utilization of resources. For example, a
participant connecting at a line rate of E1 requires 10 times more resources
than a participant connecting at a line rate of 128 Kbps.
Encrypted participants always require MUX+ resources and use more
resources than a regular participant as shown in Table 4-9, "MUX+ Cards
Port Capacity."
In a system with MUX+ cards, both encrypted and non-encrypted participants
resources are allocated and calculated according to the relative weight
assigned to the different line rates during a reservation. For example, a
MUX+40 card can host 72 non-encrypted or 48 encrypted participants in a
conference using a line rate of 128 Kbps.
The following table details the number of ports available with the MUX+
cards.
