Data and split-line configuration
This section 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
•
The UT-WAN application, performs a similar function as the DTM module, only without
using a physical data module. This feature uses an installed DTM for lines and the internal
router for data. Refer to
•
Data modules used to configure channels on a WAN interface are always configured under
DS30 Bus 08. Refer to
Configuring the DDI Mux module
The Digital Drop and Insert (DDI) Mux media bay module 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. This module is
currently available only for North American installations.

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
