FEATURE DESCRIPTION BENEFIT

Virtualization at scale Virtualization capabilities include hardware logical

routing with the JCS1200, taking control plane

scalability to a new level by decoupling the control

and forwarding planes and hosting them on separate

platforms. Using logical routers, the applications,

conﬁgurations, protocols, and routing tables assigned

to a logical router belong to that one logical router.

Juniper’s state of the art logical routing support is the

only implementation with shared uplink support.

With these capabilities, providers can manage their

CapEx by consolidating the network hierarchy onto

a single highly available router, or by scaling service

oerings in midsize to large POPs with multichassis

routers.

Solid, modular, feature-rich

soware

Each release of Junos OS runs consistently across

all Juniper Networks routing platforms and feature

sets. Junos OS was conceived and implemented as a

modular design. Advanced features include point-to-

multipoint MPLS, MPLS VPN, IPv6 provider edge, and

many more unique features in core routers.

Each Junos OS process runs in protected memory

to guard against system crashes and to ensure that

applications do not interfere with each other. Junos

OS provides the greatest breadth of features and most

stable network operating system in the industry.

Optical transport integration PIC support includes OTN G.709 at 10 Gbps, 10-Gigabit

Ethernet Tunable DWDM, OC-768, and 4-port OC-192.

Generalized MPLS (GMPLS) is continually enhanced

along with Ethernet Operation, Administration, and

Maintenance (OAM) functionality.

Integrating optical transport technology into routers

provides ﬂexibility in provisioning that leads to the

rapid rollout of new services, while retaining Layer 3

intelligence to ensure prompt responses to topology

changes.

Product Options

Key components of the T320, T640, T1600, and TX Matrix platforms are the PICs, FPCs, SIBs, Routing Engines, and control boards.

FEATURE DESCRIPTION BENEFIT

PICs High-density PICs provide a complete range of ﬁber

optic and electrical transmission interfaces to the

network.

For a listing of available PICs, see the PIC Guides at

www.juniper.net/techpubs/hardware.

FPCs The FPCs house the PFEs and provide slots for carrying

the PICs. The T Series “Enhanced FPCs” provide

additional static RAM (SRAM) for increased scaling

beneﬁts as well as more granular class-of-service

(CoS) capabilities.

• Type-1 FPCs are rated at 2 Gbps and 4 Gbps full

duplex for the T320 and T640/T1600 routers,

respectively.

• Type-2 FPCs are rated at 8 Gbps and 16 Gbps full

duplex for the T320 and T640/T1600 routers,

respectively.

• Type-3 FPCs are rated at 20 and 40 Gbps full duplex

for the T320 and T640/T1600 routers, respectively.

• Type-4 FPCs are rated at 40 Gbps full duplex for the

T640/T1600 routers.

• The T1600 Type-4 FPC is rated at 100 Gbps full

duplex and supports two Type 4 PICS.

SIBs The SIBs house the switch fabric silicon and provide

any-to-any connectivity between the FPCs.

The T Series was designed to be highly resilient, with

four active SIBs and one standby SIB per T640, T1600,

or TX Matrix chassis, and two active SIBs and one

standby SIB per T320 chassis. Each T Series router is

designed to gracefully degrade in the unlikely event

more than one SIB failure occurs.

Routing Engines (RE) The RE maintains the routing tables and controls the

routing protocols, as well as the Junos OS processes

that control the platform’s interfaces, the chassis

components, system management, and user access to

the platform.

The routing engines supported on the T Series product

family are: RE-A-1600, RE-A-2000, RE-TXP-DUO-

1800-8G-BB and RE-TXP-DUO-2600-16G-BB.

Speciﬁcations are described under Routing Engines

below.

Control Boards (CB) A control board works with each RE to provide control

and monitoring functions, such as for the power,

temperature, fans, and system resets.

The dierent control boards for the T Series family are

listed below under ordering information.
