T1, DS3, E1, E3 PICs Datasheet

DS3/E3 and T1/E1 circuits for Internet access represent a key component of service provider business. The highly dynamic nature of aggregation deployments requires that edge router interfaces be highly dependable, flexible, and operationally efficient.

Juniper Networks T1, DS3, E1, E3 Physical Interface Cards (PICs) offer highly available, highly flexible solutions for edge applications. These links deliver not only business-critical Internet connectivity, but also an ever increasing portfolio of rich IP services, such as VPNs and flexible bandwidth. Leveraging cross-platform predictable performance, uniform JUNOS software, and seamless, hardware-based features, these PICs enable service providers to rapidly deploy and provision new IP services with no performance trade-off.

New E3 4-port Intelligent Queuing (IQ) PIC offers new levels of functionality:

• Granular QoS capabilities enable carriers to offer profitable differentiated services without compromising performance. For example, with the E3 IQ PIC, traffic prioritization levels can be established with the high granularity of four queues per DLCI for Frame Relay.
• Extensive statistics on packets and bytes that are transmitted, received, or dropped. Packets can be inspected to determine what types of traffic is being transmitted, enabling carriers to bill for premium QoS and Service Level Agreement-based (SLA-based) services and to implement usage-based billing. In addition, they also provide the visibility needed into network operations to ensure that trends are anticipated and capacity is expanded to meet increasing demands.
• Rich, embedded diagnostic tools help network managers troubleshoot links using in band loopback testing and bit error rate diagnostics, supporting quicker provisioning, activation, servicing, and recovery.

DS3 and E3 Integrated DSU
The DS3 PIC is interoperable with Digital Link, Kentrox, and Larscom scrambling mechanisms and Digital Link and Larscom subrate mechanisms. E3 PICs are interoperable with Digital Link subrate mechanisms and Kentrox and Digital Link scrambling mechanisms.

The integrated DSU functionality provides subrate DS3 and subrate E3 connectivity, enables more efficient use of POP rack space, and simplifies circuit management. Moreover, it reduces the number of devices that need to be managed and enables service providers to configure all devices through a single user interface.

Rich Service Creation
These PICs support a full suite of rate limiting features to enable service providers to control the bandwidth on access circuits without having to rely on DSU reconfiguration on the CPE. By simply adjusting the bandwidth rate-limiting configuration on the provider side, service providers can easily move subscribers from one bandwidth tier to another. A fine granularity of rate limiting (for example, by traffic type) is also supported.

IQ PICs support comprehensive QoS capabilities per logical interface for per-DLCI frame relay services. These PICs support ingress and egress policing and egress rate shaping. Service providers can then configure the router's random early detection (RED) or weighted RED mechanisms on outbound interfaces to drop out-of-profile packets more aggressively. Supports 4 queues per logical interface with weighted round robin scheduling and strict priority queuing for traffic prioritization on a per customer basis.

N x E1/T1 Service with MLPPP and MLFR
Using the E1 or T1 PIC with the Multilink Services PIC, service providers can provide n x E1 and n x T1 access service using MLPPP (RFC 1990) or MLFR (FRF.15 or FRF .16). The Link Services PIC bundles up to eight E1 or T1 links per interface, enabling service providers to leverage the existing E1 or T1 copper infrastructure for multimegabit tiered services, rather than migrating to a new capital instensive infrastructure, such as DS3 or E3. By using these PICs together, service providers can aggregate hundreds of multilink bundles in a single chassis without compromising forwarding performance. Any port on any PIC can be bundled with any other number of ports on any number of PICs, no constraints. This multilink solution enables service providers to offer a dynamic solution for growing bandwidth requirements from 1.5 Mbps to 12 Mb
