Juniper P-AS2-LAYER2SERVICES M-series / T-series routers Router Line Card

The Juniper P-AS2-LAYER2SERVICES is a Adaptive Services II (ASII), Layer 2 service package Physical Interface Card (PIC) built for Juniper’s M-series and T-series multiservice edge and core routing platforms. It provides a single an internal services-processing engine (no external network port). It runs the Adaptive Services II Layer 2 service package for deeper packet inspection and Layer 2 service provisioning, confirmed by Juniper’s own service-package documentation and by reseller listings for the closely related PB-AS2-LAYER2SERVICES-A and PE-AS2-LAYER2SERVICES-A variants. Like other PICs in this family, it installs into a Flexible PIC Concentrator (FPC) slot, where it handles line-rate framing and signalling for its media type before handing traffic to the router’s Packet Forwarding Engine for switching and lookup. These interface cards remain in active service on long-lifecycle M-series and T-series deployments still running Junos in production networks, and are commonly sourced as maintenance spares, capacity expansion, or like-for-like replacements when a card fails. Tech-Star (UK-based, shipped worldwide) stocks a wide range of Juniper interface cards, power modules and control-plane boards for these platforms.
