The Peripheral Module houses the plug-in boards that provide the interface to end-user equipment. The number of positions in a shelf depends on the iS3000 model. Each pair shares 32 time-slots of the switching network via a dedicated 2Mbits/s backplane bus. A few special positions have access to a full 2Mbits/s group.

The different types of available plug-in boards can be freely mixed across the different positions. A plug-in board can be inserted in a free position without needing to disconnect the power or to restart the system.

Each PM has its own AC/DC Power-Supply Unit (PSU) to keep the risk of common failure to an absolute minimum.
