PIM and VoIP Module Overview

J-series Services Routers accept Physical Interface Modules (PIMs) and Avaya VoIP modules in the slots on the front of the chassis.

Caution: PIMs and VoIP modules are not hot-swappable. You must power off the Services Router before removing or inserting a PIM or VoIP module. Ensure that the PIMs and VoIP modules are installed in the router chassis before booting up the system.

A Physical Interface Module (PIM) is a network interface card that is installed on a J-series Services Router, to provide physical connections to a LAN or a WAN. The PIM receives incoming packets from the network and transmits outgoing packets to the network. Each 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 framing and line-speed signaling for its medium type.

For a complete list of supported PIMs, see Field-Replaceable PIMs.

Avaya VoIP modules are installed in the router chassis like PIMs, but are controlled by the Avaya Communication Manager (CM) software rather than the JUNOS Internet software. For a complete list of supported modules, see Avaya VoIP Modules.
