Figure 3-7: Signal flow process
Information enters the MGC units from the telecommunications network via a
PBX or CSU, and into the Network Interface Module. The information is then
transferred to the MUX Module via the Internet.
The MUX Module transfers the control information to the Main Control
Module via the Control Bus. The control information is then processed by the
Main Control Module and a control response forwarded via the Control Bus
to the appropriate MUX Ports.
