OPS Line Card (North America Only)
The OPS Line Card contains six off-premises line circuits. An Off-Premises (OPS) line circuit
is used where the line goes outside the building that houses the PBX and the line may be
exposed to extraneous high voltages or induced currents.
Peripheral Interface Module Carrier Card
The Peripheral Interface Module Carrier Card (PIMCC) holds a FIM II or CIM to provide the
fiber or copper interface between a peripheral cabinet and the 3300 ICP. The FIM II and CIM
interface modules on the BCC III also provide the connectivity needed to the 3300 ICP, making
the PIMCC dispensable.
The Peripheral Interface Module Carrier card plugs into slot 12 of an SX-200 cabinet.
System Resources: Processors, Cards, and Modules
This section describes the cards and modules that support the system. To meet site
requirements, you may need to add additional system resources to the controller. When
planning a site, refer to the Configuration Tables in the Engineering Guidelines to determine if
additional system resources, such as compression, echo cancellation, or Ethernet-to-TDM
(E2T) channels are required.
Processors (E2T/RTC)
The CX/CX(i), AX, and standard MXe Controllers use a single processor to perform the Real
Time Controller (RTC) functions and the Ethernet-to-TDM (E2T) functions. The expanded MXe
Controller and MXe Server have separate processors for these functions.
The E2T converts voice streaming between Internet Protocol and Time Division Multiplexing
(TDM) signals. The RTC runs the call control for the controller and acts as a gateway for the
IP signals/packets.
Digital Signal Processor Modules
The Digital Signal Processor (DSP) Modules perform basic telephony and compression
functions including:
Conferencing
Voice Mail playout and recording
Call Progression tone generation and detection
Auto-attendant support
G.729a compression (for IP trunking and wireless phones)
FAX over IP (T.38) and additional G.729a compression (provided by the high-density
DSP II MMC)
The system allocates DSPs for
