Connecting the JCS1200 Platform to a T Series Core Router
The benefits of the JCS1200 and T Series routers as a single platform are:
Increased efficiency and investment protection—A single T Series router used with the
JCS1200 platform supports up to eight Protected System Domains (PSDs). With
multiple (up to 3) T Series chassis connected to the JCS1200 chassis, 12 PSDs can be
supported. Instead of purchasing 12 physical routers, a service provider can configure
12 PSDs using a single interconnected platform. In addition, operations and
administration are simplified through consolidation of resources.
Maximum scaling and flexibility—A highly scalable control plane chassis preserves
slots in the router chassis that can be used for revenue-generating, high-speed
forwarding of Internet traffic. Service providers can assign control processors and
memory space on the Routing Engines in the JCS chassis to achieve the most efficient
use of resources, while delivering outstanding performance. In addition, different PSDs
can share interfaces on a single Physical Interface Card (PIC), reducing capital
expenditure and enabling you to allocate resources with finer granularity.
Rapid service rollout—New services can be planned, tested, and deployed more quickly
with fewer resources. Each PSD provides a secure administration domain, where new
features can be tested, while other PSDs continue to provide tested software to
customers. Through fault isolation and streamlined administration domains, service
providers achieve faster revenue and accommodate rapid customer growth. In addition,
RSDs and PSDs can run different version of Junos OS; however, the supported Junos
OS Release version must be one release up, or one release down, from the current
Junos OS Release version. For example, if RSD is running Junos OS Release 10.1, then
PSD can run Junos OS Release 10.0 or 10.2, however, it cannot run Junos OS Release
9.6 or 10.3. Each RSD and PSD must be running Junos Release 9.4 or later.
The following sections discuss some of these benefits:

Network Consolidation
Many carriers operate separate IP networks for public and private services. Others have
application-specific IP networks (voice and video, for example). PSDs enable carriers to
consolidate and simplify network architecture. Rather than adding more routing at the
edge to support individual services, a single platform provides service-specific virtualization
in the core of the network.
