Each system supports an SRP module and a selection of line modules. You can use any line module for access or uplink . Access line modules receive traffic from low-speed circuits, and the system routes the traffic onto higher-speed uplink line modules and then to the core of the network.

Each module connects to a corresponding I/O module via a passive midplane. See Figure 8.

The front panel of each module contains a collection of status LEDs (light-emitting diodes). For information about how to interpret the LEDs, see “Troubleshooting” on page 103.
