32GC
Group Controller Card
3
The 32GC card serves as the communication link in the Coral FlexiCom 6000 system,
between the MCP-ATS and the PB-ATS cards (located in peripheral shelves), or the
FLMS cards (located in FlexLITE remote peripheral shelves); via the MPG-ATS
located at the motherboard rear backplane. Each of the redundant 32GC cards
interfaces with the same MPG-ATS which controls the bus signalling to the PB-ATSs,

32GC Communication
Schematic
The 32GC card contains the High-Level Data Link Control (HDLC) bus interface
circuitry, Pulse Code Modulation (PCM) bus interface circuitry, clock circuitry to
synchronize the peripheral section of the system, and digital tone generators (dial,
busy, ringing, ringback, DTMF, MFC, and test). Additionally, the 32GC card contains
circuitry to synchronize the Coral peripheral clock to an external clock derived from
a digital trunk interface. The 32GC card supports eight HDLC highways and
thirty-two PCM streams, and up to sixteen peripheral shelves. It is capable of
establishing a maximum of 2000 calls between ports on its maximum peripheral shelf
capacity. This matrix allows for a constant frame delay operation mode.
The 32GC card also houses the proprietary Mirrored Memory and Switching Matrix
essential for the Hot Standby control system. With this technology, the
Standby
control system set
snoops
relevant information from the
Active
control system set.
With this information it readies its control card set for takeover of the control functions
at any time it may become necessary.
