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
SV9100 is connected to another UNIVERGE
SV9100 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
SV9100 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.
