# Configuring the system overview

The NMS hardware that provides the physical interface for DLCP is designed for flexibility to support a wide variety of applications. You must configure the hardware to suit DLCP applications. You can customize the hardware configuration by creating configuration files (system configuration and board keyword files) or editing the sample configuration files that accompany DLCP software.

Step | Description
1 | Create or edit an NMS OAM system configuration file and board keyword files. | Specify system and board keyword settings that optimize the CG hardware configuration for the DLCP environment.
2 | Run the oamsys utility with the edited NMS OAM configuration files. | Updates the NMS OAM configuration database and configure the CG hardware on the system. For more information, refer to the NMS OAM System User's Manual.
3 | Run one of the demonstration programs nms303tool or nmsv5tool. | Verifies that the DLCP software can initialize a Layer 1 for GR303 or V5.2 protocols, set up provisioning, start interfaces, perform transmit and receive HDLC operations, and report trunk alarms and performance statistics.
