Juniper JX-2T1-RJ48-S Internal 1.544Mbit/s networking card

2-port Channelized T1 PIM w/ CSU/DSU The Juniper Networks Dual-port T1/E1 PIM provides the physical connection to T1 or E1 network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. The Dual-port T1/E1 PIM is equipped with a dedicated network processor that forwards incoming data packets to the Routing Engine, and receives outgoing data packets from the Routing Engine. During this process, the PIM performs T1 or E1 framing and line-speed signaling.

When a Dual-port T1/E1 PIM is installed in a Juniper Networks® SSG Series Secure Services Gateway running ScreenOS® Software, the dedicated network processor will forward traffic to the SSG Series CPU where traffic decisions are made based upon security policies.
