Chapter 3 Hardware Installation and Connections

Connect a Telco-50 connector to one end of the cable (see 

 for pin 

assignments) and connect the other end directly to an MDF; alternatively attach RJ-11 
connectors and connect directly to DSL modem(s).  

Figure 20   Telco-50 Cable with RJ-11 Connectors

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 

 for example splitter chassis rear panel 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.
