With the introduction of PCI Express® servers
as the latest standard for PCI-based solutions,
telecom OEMs and integrators will require
high-density, highly advanced I/O solutions
for use in these new servers. Included with
the PCE335-HSI is enabling software that
provides a transparent interface to the SunLink ™
WAN packages. This combination of powerful
hardware and software allows for the creation
of high-density, high performance access
solutions for telecom and IP telephony systems
when deployed in these new servers.
The PCE335-HSI high-speed synchronous
WAN Communications Adapter provides four
high performance synchronous/serial channels
for WAN connectivity. The adapter is ideally
suited for use within SS7 nodes, radar servers,
frame relay access devices, high-speed
modems, and other high-speed communications devices. The PCE335-HSI is part of PT’s
industry-leading family of access solutions,
compute solutions, and award-winning software and high availability middleware for
embedded applications.
Hardware Features
The PCE335-HSI is designed as a fully programmable communications subsystem capable of sustaining high data rates for a variety
of protocols used in synchronous data communications. The PCE335-HSI architecture
capitalizes on the intelligence of the Freescale
MPC8270 Quad Integrated Communications
Controller (PowerQUICC® II), enabling it to
act as a specialized communications controller.
The PCE335-HSI adapter enhances overall
system performance by using its onboard
intelligence and 128 MB of SDRAM array to
handle much of the low-level communications
that typically burden the host system, and
relegates most of the serial I/O communication
-related processing to the PCE335-HSI. In
addition, the SDRAM eliminates start-up
delays associated with application download
wait times by enabling the code to be executed
directly onboard.
HSI Software Support
The HSI software included provides compatibility with Solstice™ WAN software packages
available through Sun Microsystems. The HSI
software is a transparent interface on PT’s
PCE335-HSI adapter, providing a compliant
environment for SunLink WAN packages operating on similar Sun communication modules.
The protocols that operate with the PCE335HSI adapter include the Solstice X.25 and
Solstice Point-to-Point Protocol (PPP). PT’s
HSI adapter conforms to the Sun Synchronous
Serial Driver Interface Specification.
The HSI software also includes utilities that
enable the modification of some hardware
operating modes common to synchronous
serial lines. These modifications are used for
the operation of some communications packages or in troubleshooting links, packages,
PT offers the PCE335-HSI.
