System Description
Coral System General Features
The Coral 800 is a digital communications switching system, available in a variety of
configurations that share a common architecture. The Coral system is based on Pulse
Coded Modulation (PCM) switching technology. The active circuitry of the system is
contained on removable printed circuit assemblies or cards, nearly all of which may be
used in any system in the family.
The active circuitry of the Coral 800 system is divided into two major categories:
common control and peripheral circuitry. The common control circuitry directs call
traffic through the system, establishing audio connections between peripheral ports.
The peripheral circuitry provides the hardware necessary to establish those
connections. Instructions from the common control circuitry to the peripheral circuitry,
and status information from the peripheral circuitry to the common control circuitry
are passed through the group controller. The group controller provides driver and time
slot interchange functions for the PCM highways and the HDLC channels.
The peripheral circuitry is further divided into Shared Service and Peripheral Interface
functions. The shared service circuitry provides the equipment necessary to establish
calls between Peripheral interfaces. The Peripheral Interface circuitry provides
standardized electrical connections to external telephone station equipment and
network facilities.
Coral System Configurations
The major distinction between different Coral system configurations is their number of
card slots, into which Shared Service and Peripheral Interface cards may be inserted.
The Coral IPx 800 system is a highly cost-effective rack-mounted design, including up
to 30 universal card slots or 3 cages. The Coral IPx 800 cage operates from a standard
100-240VAC 47-63Hz power source, or from a 48 volt direct current (DC) stationary
battery.
The Coral IPx 3000 system has the same rack-mounted design as the Coral IPx 800, but
includes more cage options, including up to 178 universal card slots or 16 cages. The
Coral IPx 3000 offers the option of operating from either 100-240VAC 47-63Hz, or from
a 48 volt direct current (DC) stationary battery plant for increased service reliability.
