Installation Notes for Clock Interface Modules
•
Main modules and spoke modules are not hot-swappable.
•
Nonvoice modules and voice modules can be installed in any slot.
•
Main clock RTMs must be installed in slot 0 behind either a serial module or a T1/E1 module.
•
Spoke RTMs must be installed behind serial modules and the lowest-numbered T1/E1 slot.
•
If a T1/E1 module is installed in the slot that is closest to the processor, a spoke RTM is not needed
behind any T1/E1 modules. They will synchronize to the H.100 clock.
•
For platforms with only nonvoice boards (serial or T1/E1 module), only a main RTM is needed for external
clock reference input.
NOTE: The clock RTM is installed in the rear of slot 0 next to the CPU slot. When you upgrade
from an older processor to a PP833 processor, you can leave the CPU RTM in the chassis. Leaving
the CPU RTM in the chassis will not adversely affect the functioning of the PP833 processor.
Leaving the RTM installed will provide proper airflow within the CTP node.

CTP2000 PMC Module
The PCI mezzanine card (PMC) is mounted on the processor module and can be installed or replaced in
the field. Two PMC slots are available in the processor’s front panel to support two compatible PMC
modules. Figure 28 on page 31 displays the location of the PMC module on the CPU card. The following
PMC modules are available:
•
CTP-FX2000GE-UPG—Dual SC multimode fiber Gigabit Ethernet PMC module offers dual 1000 Mbit
Ethernet connectivity with SX signaling on an SC fiber connector.
•
CTP-FX2000FE-UPG—Dual SC multimode fiber Fast Ethernet PMC module offers dual 100FX Fast
Ethernet connectivity on an SC fiber connector.
•
CTP-Fiber-PMC—Fiber PMC card supports up to two SFP modules. Supported SFP modules are:
•
CTP-SFP-1GE-T: Small form-factor pluggable 1000BASE-T Gigabit Ethernet module (uses Cat 5 cable)
