Support of Real-Time Traffic (TDM)
The PRS Q-80G addresses the technical
challenges (latency, jitter) of merging
real-time traffic with other traffic types over a
single communication infrastructure:
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 Q-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.
Multiple QoS Options
The PRS Q-80G can be suited to the
application specific QoS requirements thanks
to multiple traffic scheduling options:
Strict traffic priority scheduling
Configurable credit table (weighted
round-robin) to guarantee bandwidth to
lower priority traffic
Switch Board Redundancy for
High Availability
The PRS Q-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 Q-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
the traffic of the failing board), and
maintenance switchover between switch
boards (without any service interruption and
no cell loss).
Control Software
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.
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.
Backward Compatibility
The PRS Q-80G, PRS C48X, and
PRS C192X chipset offers backward
compatibility enabling co-population of both
existing and new line cards in the same
chassis: the PRS Q-80G switch chip SerDes
can operate at 2.5 Gbps per serial link
(instead of 3.2 Gbps) to support line cards
based on the previous PRS C192 fabric
interface chip, while the PRS C48X and
PRS C192X interface chips SerDes can
operate at 2.5 Gbps per serial link (instead of
3.2 Gbps) to operate with switch cards based
on the previous PRS 64Gu or PRS Q-64G
switch chips.
