Making Cable Connections
This section provides the instructions you need to make the necessary cable
connections to:
POTS splitter shelf or MDF
Ethernet hubs or switches
SNMP management system
Terminal, laptop computer, or modem
Special Connection Considerations
There are several steps that you must take to maximize loop reach.
Use 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.
Make sure the main bundle of the loop is standard twisted-pair voice cable
(CAT3).
For multiple DSL circuits in the same main bundle, choose non-adjacent wire
pairs whenever possible.
Use only non-conditioned loops (no load coils, echo suppression, etc.)
Eliminate any non-twisted cable from the loop.
Always keep TIP and RING in the same twisted-cable pair.
