UNIVERGE SV8100/SV8300
System Hardware Manual
Four analog 4-circuit tie line interfaces
Two Blade status LEDs
Two straps and one switch per circuit to determine the circuit type
Limitation depends on the connecting Router,
Multiplexer or Exchange. If the UNIVERGE
SV8100/SV8300 is connected to another
UNIVERGE SV8100/SV8300 directly, there is up
to 1,500 ohms loop resistance (including system).

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/SV8300 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.
