Shelf
Shelves are designed for 19” rack or wall mounting. Each shelf has 12
universal card slots. The first two slots are reserved for controller
cards, the remaining ten slots are for Interface Modules. Wiring to
each card is on the front panel. Power is -48V DC through the back or
side panel.
System Controller (CSC or CSO301, 306, and 320)
Each system requires one system controller card, which occupies two
slots (slots 1 and 2) in the main shelf. The system controller supports
call routing within the entire system and to external ports. Each
model number of System Controller (301, 306, and 320) supports a
different number of expansion shelves. The CSO model System
Controller supports Open Application Interface (OAI) enabled
expansion shelves.
Two RS-232 serial ports are provided on the system controller. Serial
ports can be used for multiple purposes, including local
administration, remote administration and diagnostics (via modem),
OAI applications and call detail recording. One standard 10-base T
Ethernet port is also provided (for future use).
Expansion Shelf (CSC300, CSO300)
An Expansion Shelf Controller (CSC300) resides in slot 2 of each
expansion shelf. The Expansion Shelf Controller manages intra-shelf
traffic and communicates with the system controller. The CSO300
Expansion Shelf Controller supports an OAI enabled expansion shelf.
Part Numbers with a CSO prefix have the same functionality and
capacity as the corresponding CSC Part Numbers and also support
the Open Application Interface(OAI)
Interface Modules (CPA, CPU, CPM, CPP, CPF316)
Telephone line and Base Station connections are made to the Interface
Module. Each card provides 16 line (handset) interfaces and 6 Base
Station interfaces. Interface Modules are installed in slots 3 through 12
on a shelf. Interface Modules include: Analog (CPA316), Universal
(CPU316), Mitel interface (CPM316), four-wire digital (CPF316), and
Panasonic (CPP316). The Interface Module type is defined via the
