Technical Manual
U-SYS MRS6100 Media Resource Server
I. System support subsystem
This subsystem loads the software or data, manages and maintains the devices, and
implements the inter-board communication.
It includes the System Management Unit (SMUI), the System Interface Unit (SIUI) of
the SMUI, and the Hot-Swap and Control Unit (HSCI).
SMUI
The SMUI is the main control board of the frame. It loads the devices, configures the
data, and controls their working status.
HSCI
The HSCI implements the bridging between the left and right shared resource buses,
board hot swap control, and intra-frame Ethernet bus switching.
The HSCI does not include a CPU. It is configured and maintained through the shared
resource bus by the SMUI.
II. Call processing subsystem
This subsystem provides the call processing function for the SIP and the MGCP.
The Media Call Control Unit (MCCU) resolves the SIP and the MGCP. The VPS
interprets the VXML script. The MCCU and the VPS communicates with the Media
Service Unit (MSU) through the internal Ethernet bus to control the MSU for media
processing.
III. Media processing subsystem
This subsystem processes the media streams, including
RTP/RTCP
Voice codec
Conference bridge
faxes
IV. O&M subsystem
This subsystem manages and maintains the entire system. It consists of the following
devices:
Back Administration Module (BAM)
Work Station (WS)
Emergency WS
