CS 1000M and Meridian 1"core" processor cards support extensive networking and provide intensive use of software features and applications, including call centers of up to 1000 agents.
The core software architecture incorporates a
All core overlays reside in Dynamic Random Access Memory (DRAM) after they are loaded from the hard disk during an initial software load (software is shipped on redundant hard disks). The Resident Overlays featured in
The capacity enhancement in the core architecture is provided by the core control complex. In Large Systems with cPCI Core/Network modules, the core control complex refers to the two Core/Network modules (Core/Network 0 and Core/Network 1). The Core and Core/Network modules are fully redundant, with Core 1 duplicating the contents of Core 0.
The backplane in the CS 1000M MGand Meridian 1 PBX 81C CP PIVCore modules is a compact Peripheral Component Interconnect (PCI) data bus. PCI provides a
The backplane in the system is divided into "core" and "network" sides. The "network" side allows up to eight network cards to be installed for call processing capability.
In the CS 1000M HGand Option 51C Core/Network module, the core side houses the following equipment:
•one Call Processor (CP) card
•one Input/Output Disk Unit with
•one
