T1600 Internet Routing Node PIC Guide

This guide provides an overview and description of the Physical Interface Cards (PICs) supported by the Juniper Networks T1600 Internet routing node. The PICs are described alphabetically. Table 1 on page 3 lists the PICs supported by the T1600 Internet routing node by PIC family.

PICs provide the physical connection to various network media types. The PICs are mounted on Flexible PIC Concentrators (FPCs), which are inserted into a slot in a routing node. A PIC typically occupies a single slot on an FPC. PICs receive incoming packets from the network and transmit outgoing packets to the network. During this process, each PIC performs framing and high-speed signaling for its media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the FPCs. Each PIC is equipped with a media-specific ASIC that performs control functions tailored to the PIC's media type. For complete information about installing PICs and transceivers, see the PIC and Transceiver Installation Instructions located at http://www.juniper.net/techpubs/.

Blank PICs resemble other PICs but do not provide any physical connection or activity. When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot and ensure proper cooling of the system.

T1600 routing nodes support the Type 1, Type 2, Type 3, and Type 4 FPCs listed in Table 2 on page 6. Table 3 on page 7 through Table 11 on page 10 provide PIC/FPC compatibility matrices for the current PICs for T1600 routing nodes.

For a complete list of end-of-life FPCs and end-of-life Enhanced FPCs for M-series and T-series routing platforms, see the M-series and T-series Routing Platform End-of-Life FPC Guide located at http://www.juniper.net/techpubs/.

Combinations of PICs—In most cases, you can install PICs of different media types on the same FPC as long as the FPC and the routing platform support those PICs. However, configuration rules might limit certain combinations of PICs on some platforms. If you have different PIC families on a single FPC and are running JUNOS

6.3or later, review the configuration rules to plan which PICs to install on the FPCs for your routing platform. Consult the most recent technical bulletins about configuration rules for PIC combinations on the Juniper Networks Support site at

http://www.juniper.net/support/.

Newer JUNOS services for some PICs can require significant Internet Processor ASIC memory. Ethernet and SONET PICs typically do not use large amounts of memory. Gigabit Ethernet, ATM2, IQ serial PICs, and Adaptive Services PICs use more. To conserve memory, you can group PICs in the same family together on the same FPC.

When you upgrade to JUNOS Release 7.5 or later, a warning appears if any configuration rules affect your PIC combinations. If you continue the installation, one or more PICs might appear to be online (the LEDs are on), but the JUNOS software cannot enable them and they cannot pass traffic. As a workaround, you can:

Install a JUNOS release that supports the combination

Install PICs on a different FPC

Remove PICs from the affected FPC

T1600 specifications

Juniper Networks T1600 is a robust, high-performance router designed for service provider and large enterprise networks. As part of Juniper's T series of routers, the T1600 is engineered to facilitate efficient and scalable network operations, making it ideal for environments requiring intensive data traffic management.

One of the T1600's standout features is its capacity to deliver a high level of performance while maintaining reliability. The router supports multiple interfaces, including Ethernet, MPLS, and IPv4/IPv6, allowing for flexible connectivity options tailored to a variety of deployment scenarios. With a forwarding capacity of up to 3.2 terabits per second, the T1600 ensures that network demands are met with ease, even during peak usage.

The T1600 is equipped with advanced technologies that enhance its operational capabilities. Its architecture is built on Juniper's proprietary Junos operating system, which provides a stable and secure platform for managing the various networking protocols. The software enables seamless integration of security, routing, and switching functionalities, reducing the complexity of network management.

Additionally, the router features IPv6 readiness, preparing networks for the next generation of internet traffic. This future-proofing addresses the inevitable exhaustion of IPv4 addresses and caters to the increasing demand for internet-connected devices globally.

Redundancy and fault tolerance are intrinsic to the T1600's design, ensuring continuous operation and minimal downtime. Its modular architecture allows for easy upgrades and replacement of components, facilitating maintenance without significantly impacting network performance.

The T1600 also supports advanced Quality of Service (QoS) features, enabling network administrators to prioritize traffic according to business needs. This capability is crucial for applications that require consistent performance, such as VoIP and video conferencing, where latency and jitter can severely impact user experience.

Scalability is another critical characteristic of the T1600. As network demands grow, organizations can add capacity incrementally, ensuring that infrastructure investments align with evolving requirements.

In summary, Juniper Networks T1600 is a high-capacity, reliable router featuring advanced routing capabilities, robust security, and exceptional redundancy. Its integration of cutting-edge technologies positions it as a powerful solution for enterprises and service providers striving to enhance their networking infrastructure for the future.
