Card Function
The PBD24S resides in the rear panel of the peripheral cabinet backplane, on the back
side of slot 1, of the odd numbered peripheral shelves, where the PB-ATS card(s) are
not installed.
The Coral FlexiCom 6000 system main processor, MCP-ATS, converses through the
32GC with the peripheral devices via the PB-ATS card(s).
The 32GC card communications are carried out via the MPG-ATS card located on the
backplane behind it, on the rear side of the Common Control shelf.
Both PB-ATS card communications are carried via the PBD-ATS card, connected to
the even numbered shelves backplane behind it, on the rear side of slot 1 and slot 2.
The data and signaling communication between the MPG-ATS and the PBD-ATS is
established via various cables that connect these cards, as described above in the
and
Each PB-ATS card can support one Peripheral Unit, composed of one or two
peripheral shelves. When a PB-ATS card supports two peripheral shelves, the card(s)
are installed in slot 1 and/or 2 of the first shelf (even numbered) of the Peripheral Unit,
with one PBD-ATS on the rear side of both slots. The connected shelf (odd numbered)
requires a PBD24S card installed on the rear side of slot 1 to complete the
communications to the odd shelf from the PBD-ATS.
The physical connections between the cards is illustrated in
Slot #1 with a PBD24S on its rear side, (where a PB-ATS is not installed) can
be used to accommodate any Shared Service card, or any card that does not
require I/O connections.
