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 Operator’s Console and software when the card is installed. Interface Modules of
different interface types can be mixed within a shelf.
Interface Modules are “hot swappable”; they can be removed and replaced without
affecting service on the rest of the system.
Intershelf Junction Panel (JPI300)
The Intershelf Junction Panel (JPI300) connects Expansion Shelf Controllers on
expansion shelves to the system controller, creating a completed communication
channel between network elements. The Intershelf Junction Panel physically
connects the network, converting RJ-21 connections from the System Controller to
the RJ-45 connection on the Shelf Controller.
