Installing the DDI MUX

The Business Communications Manager Digital Drop & Insert (DDI) MUX enables a Business

Communications Manager system to share its connection to a Universal T1 network with a local

area network (LAN). A DDI MUX allows you to make more efficient use of your digital network

resources and reduces the amount of equipment needed to support your voice and data networks.

The DDI MUX:

• provides the functionality of a DTM media bay module (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 CSU (Channel Service Unit) or DSU (Data Service Unit) 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 DDI MUX and the internal Business Communications

Manager components, and between the DDI MUX and digital terminal equipment
