Chapter 2. APPLICATIONS
The D/I Mux III is a feature-rich product that can be configured to meet specific communications
requirements. Since the diversity of T1 networks and the circuits they transport is vast, users continue to
find new and innovative ways to use the D/I Mux III.
Several major applications and their modes of operation are described in this manual. These examples
can be used to gain an understanding of various network topologies.
Channel Bank
Channel bank operation is used to connect directly to the public network, or to create a point-to-point
private network.
Point-to-Public Network
In a point-to-public network a D/I Mux III is connected directly to the public network, as
depicted in Figure 2-1. In this configuration, the D/I Mux III connects T1 to the public digital
switching system.
Network-compatible circuits are a requirement, and include all of Coastcom's standard voice
frequency interfaces and Digital Dataphone Service (DDS) data cards. Each circuit is given a
telephone number or circuit identifier. Calls are routed and set up by the public digital
switching network. Calls and connections are initiated at the D/I Mux III, or at any location in
the network with a compatible type circuit.

III can connect directly to telephones, key systems, and Private Branch Exchanges (PBXs). It
can also connect to 800, Megacom, Direct Inward Dialing (DID) services, and direct outbound
dialing (DOD).
