5.2.3 SHDSL WAN Cabling
Each SHDSL port provides up to four wire-pairs, which can support up to two RJ-11
physical connectors.
Warnings:
• The device does not include primary telecom protection! When the DSL telephone
lines are routed outside the building, additional protection - usually a 350V three-
electrode Gas Discharge Tube (GDT) as described in ITU-T K.44 - must be provided
at the entry point of the telecom wires into the building (usually on the main
distribution frame / MDF), in conjunction with proper grounding. The center pin of the
GDT (MDF grounding bar) must be connected to the equipotential grounding bus bar
of the Telecommunication room.
• To protect against electrical shock and fire, use a minimum 26-AWG wire to connect
the DSL ports.
Note: SHDSL is applicable only to Mediant 800B MSBR.
