Figure 3-27 CD-CP00 Blade Installed
Installing Expansion Blade in the 19" Chassis (Optional)
When adding additional chassis to the system to expand the capacity, a
PZ-BS10 must be installed in the Controlling Chassis and a PZ-BS11 must
be installed in all Expansion Chassis. This connection is required with
any multiple-chassis setup.
The PZ-BS10 connects the Controlling Chassis to the Expansion Chassis
by connecting to a PZ-BS11, which is installed on each Expansion
Chassis. These Expansion Interface Units allow the CPU to
transmit/receive data as required to the additional chassis.
The PZ-BS10 is installed in the Expansion Bay of the Controlling Chassis
which is equipped with a CD-CP00 Blade. The PZ-BS11 is installed in the
expansion slot of the Expansion Chassis, which does not have a CD-CP00
Blade.
The EXIFU cable connects the Controlling Chassis and its PZ-BS10
interface to the second, third, and fourth PZ-BS11 interface.
Use only the CAT 5 cables provided by NEC to make the connections
between the Controlling and Expansion Chassis.
The PZ-BS10 provides:

Communication Processor Interface for data handling through
Communication Channel (24 slots maximum)

64 Channels for Telephony Resource (e.g., DTMF Tone Receiver,
Call Progress Tone Detector, MFC Tone Receiver, Caller ID Receiver,
Caller ID Signal Sender)

DSP Resource Management
