Making Cable Connections

This section provides the instructions you need to make the necessary cable connections to:

HPOTS splitter shelf or MDF

HEthernet hubs or switches

HSNMP management system

HTerminal, laptop computer, or modem

Special Connection Considerations

There are several steps that you must take to maximize loop reach.

HUse only CAT3 or better twisted-pair network connection cables for DSL Termination Unit connections and interface patch cabling. Untwisted analog cables of any length anywhere in the loop substantially contribute to crosstalk and reduced loop reach.

HMake sure the main bundle of the loop is standard twisted-pair voice cable (CAT3).

HFor multiple DSL circuits in the same main bundle, choose non-adjacent wire pairs whenever possible.

HUse only non-conditioned loops (no load coils, echo suppression, etc.)

HEliminate any non-twisted cable from the loop.

HAlways keep TIP and RING in the same twisted-cable pair.
