Juniper Networks ATM and ATM2 IQ Physical Interface Cards (PICs) offer flexible, highly-available solutions for the termination of ATM access networks, and provide support for the progressive transition to an all-IP/MPLS infrastructure. The ATM2 IQ PICs provide a very rich and robust set of quality of service (QoS) and traffic management features aimed at facilitating:
- The seamless and progressive network transformation from a legacy ATM backbone to an all-IP/MPLS infrastructure
- The introduction of new revenue-generating IP services to ATM-connected enterprises, such as Layer 2 and Layer 3 provider-provisioned VPNs
Variants On This Model Include:
- PE-1CHSTM1-SMIR, 1-port Channelized STM1-E1 PIC
- PE-1CHSTM1-SMIR-QPP, 1-Port Channelized STM1 to DS0 Services PIC with QPP, SM, IR
Supported by both the Juniper Networks M-series and T-series routers, the ATM2 Intelligent Queuing (IQ) PICs are available in 4-port DS3, 2-port and 4-port E3, 2-port OC-3, 1-port OC-12, and 2-port OC-12 versions. The ATM2 IQ PICs leverage the JUNOS operating system's MPLS traffic engineering and hardware-based QoS capabilities to deliver seamless transport of multiservice traffic over the IP/MPLS infrastructure. Designed to provide rich, granular ATM QoS and signaling functionalities, the ATM2 IQ PICs are a key element in the delivery of a guaranteed high-quality, end-to-end user experience.
ATM Features and Applications
- As bandwidth needs continue to increase, migrations of legacy data service and voice traffic to a converged IP/MPLS infrastructure must maintain the premium-quality service levels that users expect and rely upon. Hard-won brand equity and service revenues must be protected, and service degradation is intolerable.
- Juniper Networks understands these critical considerations, and delivers the hardware and software-based solutions to gracefully migrate business-critical traffic from ATM environments to a converged IP/MPLS network infrastructure. The ATM and ATM2 IQ PICs are central enablers of this network transformation, and are based upon a very robust set of JUNOS IP/MPLS and ATM service capabilities.
