Limitation depends on the connecting Router,
Multiplexer or Exchange. If the UNIVERGE
SV8100 is connected to another UNIVERGE
SV8100 directly, there is up to 1,500 ohms loop
resistance (including system).

Installation

1. Set the straps for either the 2-wire or 4-wire. Refer to
4-34 CD-4ODTA Blade on page
2. Install the CD-4ODTA into a slot in the chassis.
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.
