The digital drop and insert MUX media bay module (DDIM) enables a BCM system to share its connection to a universal T1 network with a local area network (LAN) to provide a combination of voice and data channels.
- Provides the functionality of a DTM (T1 digital lines only)
- Splits the incoming T1 line so that some of the lines are used for voice traffic and some of the lines are used for data traffic
- Provides either the channel service unit (CSU) or data service unit (DSU) functionality to support connections to data terminal equipment (DTE), such as a router or a bridge
- Connects to network devices that support V.35 interfaces
- Provides end-to-end transparent bit service
- Supports loopbacks between the BCM system and the internal BCM components, and between the BCM system and digital terminal equipment
