Juniper JX-DS3-S

The Juniper DS3 and E3 Physical Interface Modules (PIMs) are for use with the J-series J6300 Services Routers or the Secure Services Gateway 500 Series (SSG). These PIMs include either one physical DS3 or E3 port with integrated DSU and a physical interface port license. The Juniper DS3 or E3 PIMs provide the physical connection to DS3 or E3 network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. The Juniper DS3 or E3 PIMs are 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 framing and line-speed signaling.
