40 Chapter 3 Hardware Installation and Connections
Connect a Telco-50 connector to one end of the cable (see Section 3.5.3 on page 39 for pin
assignments) and connect the other end directly to an MDF; alternatively attach RJ-11
connectors and connect directly to DSL modem(s).

3.5.4 Splitter Chassis Rear Panel Connections
A DSL splitter card separates the voice signal from the DSL signal. It feeds the DSL signals to
the DSL line card and diverts the voice signal to the CO Telco-50 connector (or wire wrapping
pins) on the splitter chassis’ rear.
Connect the CO Telco-50 connectors to the PBX or PSTN/ISDN switch when using the
ADSL splitter card.
Connect the USER Telco-50 connectors to the subscribers’ telephone wiring. In most multi-
tenant unit applications, the USER pins connect to the subscribers’ telephone wiring via Main
Distribution Frame (MDF).
See Section 3.5.5 on page 40 for example splitter chassis rear panel connections.
3.5.5 MDF Connections
The following figure gives an overview on a possible installation scenario for the IES-5000
using the DSL line cards and splitter cards. Data and voice signals can coexist on the same
telephone wiring.
Note: Multiple upper and lower MDF port connections are shown as one line in the
following figure.
