The PRS 80G switch device and the
PRS C48X and PRS C192X fabric interface
devices are all available in two versions: the
leaded version, for lead soldering process, and
the version complying with the directive on the
Restriction of the use of certain Hazardous
Substances (RoHS) and enabling lead free

PRS 80G Switch Device, PRS C48X
and PRS C192X Fabric Interface
Devices
Switch Fabric Solution with Carrier
Class QoS Features for
Applications up to 80 Gbps
The AMCC PRS 80G is a switch device for
systems in the range of 20-to-80 Gbps of
aggregate user bandwidth. The PRS 80G is a
cell switch, shared-memory device, which
provides 80 Gbps of switching capacity. It uses
.13-micron technology and embedded
3.2-Gbps SerDes to deliver 40 Gbps (one
device) or 80 Gbps (two devices) of user
bandwidth with an overspeed factor of two.
Along with the AMCC PRS C48X and
PRS C192X fabric interface devices, the
PRS 80G addresses the critical QoS needs of
a wide range of highly demanding applications
that handle any mix of real-time and best effort
traffic in the WAN multi-services, Wireless
Infrastructure, Metro Ethernet, Enterprise, and
TDM spaces. The PRS 80G provides low
latency, carrier class QoS and full bandwidth
multicast to efficiently handle real-time traffic
(including TDM) and enable convergence of
voice, video, and data traffic over a single
network infrastructure. It fits the requirements
of the new carrier services, while leveraging
previous carrier investments by providing the
capability to switch IP and TDM traffic
concurrently on the same platform.
The PRS 80G is an integral part of a complete
system solution with AMCC's nP37xx
integrated network processor and traffic
manager products, framers, PHYs, PowerPC
processors, and software. To facilitate the
evaluation and prototyping of complete
solutions, AMCC also offers an 80-Gbps
reference switch board, as well as ATCA
Switch boards, featuring the AMCC PRS 80G.
The PRS 80G device performs the switch core
function, in configurations of one or two
devices, depending on the switching capacity
needs. The PRS C48X and PRS C192X
devices perform the queuing manager function
of the PRS 80G-based switches. An adapter
card can be equipped with either a PRS C48X
interfacing a 2.5-Gbps / OC-48 network
processor or a PRS C192X interfacing a
10-Gbps / OC-192 network processor or up to
four 2.5-Gbps / OC-48 network processors.
Scalability and Multiple Port
Speeds
The PRS 80G switch, in conjunction with the
PRS C48X and PRS C192X fabric interface
devices, provides 40 Gbps (one device) or
80 Gbps (two devices) of full-duplex aggregate
user bandwidth with an overspeed factor
per-port of two to match wire-speed
requirements for all possible traffic patterns,
with all line protocols.
The PRS 80G enables the design of switch
fabrics with up to 32 ports for network
processors that support OC-48c and multi-GE
applications, or up to eight ports for network
processors that support OC-192c, 10-Gbps,
and multi-GE applications, or any intermediate
mix of those ports.
QoS Enforcement at Media Speed
The PRS 80G enables full bandwidth
utilization of the media connected to the
payload boards, and still maintains high QoS
performance:
• End-to-end flow control mechanisms
through the switch fabric, and
programmable flow control thresholds
(including multicast), enabling 100%
utilization of the media bandwidth while
maintaining low jitter

Support of Real-Time Traffic (TDM)
Multiple QoS Options
The PRS 80G addresses the technical
challenges (latency, jitter) of merging
real-time traffic with other traffic types over a
single communication infrastructure:
The PRS 80G can be suited to the
application specific QoS requirements thanks
to multiple traffic scheduling options:
the traffic of the failing board), and
maintenance switchover between switch
boards (without any service interruption and
no cell loss).
• Strict traffic priority scheduling
Control Software
• Configurable credit table (weighted
round-robin) to guarantee bandwidth to
lower priority traffic
The control processor of the switch board
runs the AMCC Secondary Switch Controller
software (SSC), in charge of configuring,
monitoring, and controlling the switch board
operations. The SSC initializes the cell switch
device, performs diagnostics, monitors
device status, accumulates statistics, and in
a redundant switch configuration,
communicates with its peer to perform
system recovery in case of component
failure.
• Deterministic low latency, typically a few
microseconds transit delay in worst case
conditions (100% traffic load) for high
priority traffic.
• Guaranteed precedence of time-sensitive
traffic (for example, TDM) over other traffic
types, using fully preemptive traffic priority.
Full Bandwidth Multicast
The PRS 80G addresses the growing needs
of audio and video distribution applications,
thanks to its powerful multicast and
broadcast mechanisms: cell replication at
sending, with cells being scheduled at
different times for different output ports.
• Credit Table with fully preemptive highest
traffic priority (exhaustive scheduling)
Switch Board Redundancy for
High Availability
The PRS 80G can be designed to operate in
redundant switch board configurations that
address the high-availability requirements of
five-nine applications. On the payload
boards, the PRS C48X and PRS C192X
Fabric Interface chips provide a redundant
path with the switch boards.
The PRS 80G supports three redundancy
modes: hot standby mode (with automatic
takeover of the traffic of the failing active
board), traffic load sharing between the two
switch boards (with automatic take over of
2
Empowering Intelligent Networks
In addition, the AMCC Switch Integrated
Control Console (SWICC) tool, a PC software
application, enables access to any
addressable resources in the switch device to
initiate or monitor any operational or test
function (for example, traffic generation,
digital eye, sense and operate of any bit, loop
back, and so on). The SWICC can be used
locally, on the customer premises, or for
remote support.
