BCM 4.0 Networking Configuration Guide
Chapter 61
Data modules
The following discusses configuration for modules and applications that require data or
combination data/telephony line configuration.
DDI MUX modules require two DS30 bus positions. This module supports combinations of
data channels and T1 lines. A DTM (digital trunk module) contained within the module is
programmed using normal DTM line configuration. The data portion of the lines are
configured under the second DS30 bus as data lines. The DDI MUX supports using either the
internal router or an external router. Refer to “Configuring the DDI Mux module” on
page 525.
Data modules used to configure channels on a WAN interface are always configured under
DS30 Bus 08. Refer to “Configuring a data module” on page 532.
Configuring the DDI Mux module
The Digital Drop and Insert (DDI) Mux media bay module enables a BCM 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. This module is currently available only for North
American installations.
Refer to the following topics for additional information:
“Configuring DDI Mux connections” on page 528
Assigning the DDI Mux modules” on page 528
Assigning lines for voice traffic” on page 529
Assigning lines to the data module” on page 529
“Configuring the DDI Mux to work with the DTE” on page 530
DDI Mux features
The DDI Mux performs the following services:
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
