Chassis Modular Components
The Centellis CT Series 16000 chassis contains four functional hardware modular components.
Each component mounts in or to the Centellis chassis frame.
The modular components of a Centellis CT Series 16000 chassis are:
• One card cage with a CompactPCI backplane
• One serviceable fan tray holding three cooling fans
• Two power supply assemblies
• One Integrated Peripheral Tray holding two disk drives
1.6
System Applications
The Centellis CT Series 16000 system chassis was designed as a CompactPCI platform for a vari-
ety of embedded applications. Users can install up to 14 6U CompactPCI boards into the chassis.
System chassis configurations can include 3.5" hard disk drives and a CD-ROM drive.
Applications for the Centellis CT Series 16000 include:
• Telephony applications, including voice and FAX processing
• WLL applications for SS7 execution
• Firewall applications for data filtering
• Other applications with additional intelligent I/O or real-time processing boards

CompactPCI Backplane Architecture
The Centellis CT Series 16000 chassis contains a 16-slot CompactPCI backplane. Two backplane
slots for the system CPU subdivide the remaining 6U user I/O expansion slots into two indepen-
dent 7-slot segments. (Although 17 slots physically exist, a third CPU slot is an inactive "dummy"
slot.) Figure 3 shows a sample CPCI backplane layout diagram.
The J4 connector on the I/O expansion slots supports an integrated H.110 Computer Telephony
bus. This provides the backplane’s time division multiplexing capability. The H.110 bus is wired
to slots A1 thru A7 and B10 thru B16.
The CPCI backplane is a passive backplane; it holds no active components.
