Hardware architecture 37
In the CS 1000M SGand Meridian 1 PBX 61C CP PIVCore/Network
module, the core side houses the following equipment:
• one Call Processor Pentium IV ® (CP PIV) card
• one System Utility (Sys Util) card
•
one Core-to-Network Interface (cCNI) cards
• one System Utility Transition (Sys Util Trans) card
• four cCNI Transition (cCNI Trans) cards
Cabling between the CP cards allows memory shadowing and dual-CPU
operation.
The CNI and CNI-3 cards provide the interface between the IPB and the
network shelf, and between the CP card and three-port extender cards in
the network shelf. Each CNI card provides two ports. Each CNI-3 card
supports three ports. In a typical configuration, three CNI-3 cards support
eight network groups.
Software is now installed with 2 Compact Flash cards: one embedded on
the CP PIV pack (FMD) 1GB, and one hot swappable (RMD) with 512 MB.
The system uses a Security Device and an electronic Keycode to perform
security authentication. The security device is located on the utility card.
The Keycode file contains information about which features the system
provides as well as License limits.
Core/Net modules diagnose faults in field-replaceable units for all core
hardware, including cables. In case of a failure, a message appears on the
system terminal and on the Liquid Crystal Display (LCD) of the CP card.
All messages can be stored in a file for future diagnostics.
