2.4.2 Expansion (EXIFU) Blade (Figure 2-10) - P/N 0911020 and 0911022
The EXIFU blade provides a connection from the Controlling Chassis-B to the Base Chassis-B
expansion unit. This connection is required with any multiple-chassis setup (a MEMDB is also
required for multiple-chassis setup). This blade allows the CCPU to transmit/receive data as
required to the additional chassis.
The EXIFU-B1 blade (P/N 0911020) is installed in the EXIFU slot of the Controlling Chassis-B
which is equipped with a CCPU blade. The EXIFU-E1 blade (P/N 0911022) is installed in the EXIFU
slot of the Base Chassis-B, which does not have a CCPU.
The EXIFU cable is used to connect the Controlling chassis and its EXIFU-B1 interface to the
second, third, and fourth Base chassis EXIFU-E1 interface. The EXIFU can be used to connect a
19” chassis to a 9.5” chassis or 2 combined 9.5” chassis.
Use only the CAT 5 cables provided by NEC to make the connections between the Base chassis
and Expansion chassis.
The EXIFU provides:
● Communication Processor Interface for data handling through Cch (18 slots max.)
● 64 Channels for Telephony Resource (ex: DTMF Tone Receiver, Call Progress Tone
Detector, MFC Tone Receiver, Caller ID Receiver, Caller ID Signal Sender)
● DSP Resource Management
Refer to "2.4.1.2 DSP Resources" on page 2-17 for complete details on the DSP resource usage.
