When a router or multiplexer is connected
instead of a trunk, the SG terminal of the router
or multiplexer must be connected to the FG
grounding terminal on the UNIVERGE
SV8100 chassis. When a tie line trunk is
connected, the FG terminal must be connected
to the ground. If the FG terminal is not
connected correctly, the signal may fail.
When tie lines are connected to the system, be
careful of the Tip and Ring polarity.
