HighWire HW400c/2 User Reference Guide Rev 1.0 
INTRODUCTION 
The HW400c/2 is a flexible high-performance core processing platform for building 
powerful processor enabled CompactPCI (CPCI) telephony and data communications 
I/O solutions. Advanced features on the HW400c/2 include two PCI Telecom 
Mezzanine Card (PTMC) sites for CT Bus enabled I/O interfaces that are 
interconnected through a high-speed Layer 2 Gigabit Ethernet switch to the dual node 
CompactPCI Packet Switched Backplane (cPSB). The HighWire core architecture 
utilizes the Freescale MPC7447A PowerPC processor and Marvell Discovery™ III 
system controller to provide a powerful computing environment for addressing a 
wide range of communications applications. 
 
The HW400c/2 is optimized for packet-based switch fabric system architectures and 
is fully compliant with the PICMG 2.16 cPSB specification. The cPSB standard 
provides a switched fabric backplane interconnection using Ethernet technology 
overlaid on the standard CPCI J3 connector. Dual Gigabit Ethernet interfaces are 
provided on the HW400c/2 cPSB interface to support both the high availability dual 
node and reduced cost single node configurations.  
 
Full CPCI compliance and interoperability are maintained including Hot Swap, 
H.110 CT Bus and rear I/O support. 
 
2.1 Product Description 
The HW400c/2 is built on SBE’s advanced HighWire core architecture, and features 
the MPC7447A PowerPC processor, Marvell Discovery III system controller, up to 
1GB DDR SDRAM and Disk-on-Chip flash file system storage to meet the 
demanding needs of today’s telecom and datacom applications. Additional developer 
features including a serial console port and a COP emulator port help speed code 
development. The HW400c/2 also fully supports the Intelligent Platform 
Management Interface (IPMI) standard (PICMG 2.9) for system management. 
 
The two expansion sites accept both CT Bus enabled PTMC modules and standard 
PMC modules. PT2MC modules have access to the on-board local CT Bus and 
timeslot interchange fabric allowing flexible routing of TDM timeslots both between 
the PTMC sites and the H.110 backplane CT Bus. PT5MC modules also include 
Gigabit Ethernet connectivity to platform resources. The HW400c/2 automatically 
detects each module type to provide full mix and match support for using PT2MC, 
PT5MC or PMC modules in either site. 
 
The 32-bit 33-133 MHz PCI/PCI-X interface supports 3.3V signaling modules with 
full support for both front and rear I/O access per PICMG 2.3 mapping. 
 
In addition, a 10/100/1000 Ethernet port for system management and application 
flexibility is included through a front panel RJ45 connector on the board.
