necessary
The iSPAN® 4532 PMC ATM Over OC-3/STM-1
Communications Controller is designed for carrier-
class telecommunication networks supporting
the most demanding ATM applications including
broadband Internet access, second and third
generation wireless, ‘converged’ next generation
networks (i.e. softswitch environments), and
integrated voice and data over carrier and
enterprise ATM backbones. Its support for ATM
to Ethernet interworking capability provides
telco system OEMs with a gateway-on-a-card
solution for bridging dissimilar technologies. This
capability allows carriers to cost-effectively migrate
existing communications infrastructure to newer
technologies and enables future-proofing of new
equipment deployments.
This ready-to-use, intelligent OC-3/STM-1 ATM line
interface is fully standards-compliant and features
software development tools to facilitate immediate
integration into CompactPCI®, VME, or custom
telecommunications platforms. In addition, the 4532
allows direct connection to SONET or SDH facilities,
eliminating the need for additional line termination
equipment. Featuring a powerful MPC8260A
on-board RISC processor, high performance
architecture, and advanced ATM functionality, the
4532 is the industry’s best choice for a 155 Mbps
PMC I/O solution in high-availability servers driving
next-generation wireless, convergence, and
broadband access telecom applications.

iSPAN 4532 PMC ATM over OC-3c/STM-1 Communications Controller
4532 Hardware
Powerful Features for Next-Generation Telecom Applications
4532 Architecture
• Support for SONET and SDH overhead channels, including
facility Data Link channels, alarms and indications, error and
performance monitoring; connects directly to SONET/SDH
facilities
• One Fast Ethernet interface on the front panel for remote boot or
LAN capability with 10/100 Base-T transceiver
The iSPAN 4532 PMC ATM Over OC3/STM-1 Communications
Controller is a member of the Interphase line of MPC8260A-based
controllers for carrier-class telecommunications environments.
The software selectable interface for SONET OC-3c or SDH STM-1
makes the 4532 a universal interface module and enables maximum
flexibility to support multiple international standard variants with
just one board.
• One front access RS-232 TTY port provided on a 2.5 mm stereo
jack
The 64-bit, 66 MHz 60x data bus connects the core RISC CPU to
the 64-bit wide SDRAM memory and the local side of the Tundra
PowerSpan PCI bridge. I/O transfers across the bridge to the PCI
bus are executed at 32-bits, 33 MHz or 66 MHz. Also connected to
the 60x data bus is an 16-bit 8 MB downloadable Flash memory (4
MB of 8-bit Flash on original 4532 models) that can be used to store
boot code and operational firmware.
• Optional JTAG debug port
Optional Rear Access via PCI Interface Module (PIM)
• Standard PCI Interface Module (PIM) design
• Single OC-3/STM-1 interface supporting long range single-mode,
intermediate range single-mode, and short-range multimode fiber
interfaces available (see above)
The MPC8260A CPM co-processor interfaces to the SONET/
SDH ATM framer via a master UTOPIA bus interface, which in
turn connects to the optical transceiver that connects to the
transmission line. The MPC8260A CPM performs all ATM layer
functions, including ATM layer, and up to the Common Part
Convergence Sublayer (CPCS) AAL functionality. The CPM has
separate and unimpeded access to a second block of 8 MB of
SDRAM memory, which can be used for storing virtual connection
lookup tables and traffic descriptors.
A second slave-mode UTOPIA interface from the 8260A CPM
coprocessor is available to a carrier card via the PMC P3 connector,
and can carry ATM traffic to and from the carrier card. In this
mode, the 4532 can be used as the front-end to an ATM switch as a
peripheral I/O card. Furthermore, the 8260A core RISC CPU can be
disabled, in which case the 4532 utilizes the CPM co-processor and
the ATM framer only to act as the physical I/O interconnect to an
ATM link.
• Designed for use with any VITA 36-199x PIM-compatible Rear
Transition Module (RTM)
PCI Interface
• 32-bit, 33 MHz or 66 MHz PCI interface on P1 & P2 connectors
2
• PCI 2.2 master/target bus interface with I O messaging unit and
four linked list DMA
• 32-bit DMA exchanges for high-transfer performance
Telecom Clock Management
• The line interface can be configured in LT (clock slave) or NT
(clock master) mode.
• Three line synchronization sources:
• Free running internal clock
• Recovered clock (loop back timing)
• Network reference (via P3)
• The recovered line clock is available to the carrier board via the
P3 connector.
Processor/Memory
• PowerQUICC II (MPC8260A) 64-bit RISC processor allows full
support of various communications protocols, reducing host CPU
processing
