figures.

4.3 Telco-50 Cables

Telco-50 cables are used for data and voice applications with MDFs (Main Distribution
Frame), patch panels and distribution boxes. They can also be used as extension cables. Telco-
50 cables are made up of 25 twisted-pair copper wires.
Connect a Telco-50 connector to one end of the cable (see
assignments) and connect the other end directly to an MDF; alternatively attach RJ-11
connectors and connect directly to DSL modem(s).

4.4 Telco-50 Connections

The internal DSL splitters separate the voice signals from the DSL signals. They feed the DSL
signals to the IES-1248-51 and divert the voice signals to the CO Telco-50 connectors.
Connect the CO Telco-50 connectors to the PBX or PSTN/ISDN switch.
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).
