Installing Expansion Blades in the 19" Chassis (Optional)

When adding additional chassis to the system to expand the capacity, a

GPZ-BS10 must be installed in the Controlling Chassis and a GPZ-BS11

must be installed in all Expansion Chassis. This connection is required with

any multiple-chassis setup.

The GPZ-BS10 connects the Controlling Chassis to the Expansion Chassis

by connecting to a GPZ-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 GPZ-BS10 is installed in the Expansion bay Controlling Chassis which

is equipped with a CPU blade. The GPZ-BS11 is installed in the Expansion

bay of the Expansion Chassis, which does not have a CPU.

The Expansion cable connects the Controlling Chassis and its GPZ-BS10

interface to the second, third, and fourth GPZ-BS11 interface.

Use only the CAT 5 cables provided by NEC to make the connections

between the Controlling and Expansion Chassis.

The GPZ-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
