1.4 Integration into Sirius 800 Routers
The MV-801 Multiviewer fits into dedicated multiviewer module slots in a Sirius 800 router
frame. More than one MV-801 may be fitted to a router. (See
Identifying Modules and Slots in
chapter, for slot information.)
The Sirius 800 internal router architecture allows the MV-801 to tap into the signal flow within
the router at the input signals, just before the main router crosspoint. Figure 2 shows a Sirius
800 router block diagram which includes up to three MV-801 Integrated Multiviewer units.
The MV-801 uses a Sirius Multiviewer Crosspoint module (MV Crosspoint) to select which of the
router inputs the MV-801 can monitor. This is an auxiliary crosspoint which is dedicated to
multiviewer use. A Sirius 800 Multiviewer Crosspoint module is required for the MV-801.
Thus, the addition of an MV-801 Integrated Multiviewer into a Sirius router retains the router’s:
•
Main outputs.
•
Main Crosspoint redundancy.
•
Processing capability on all router inputs and outputs.
